I. BACKGROUND

Plaintiffs initiated this maritime personal injury action against Defendant on July 7, 2020. 

ECF No. [1]. Plaintiffs filed their First Amended Complaint, ECF No. [8] (“Amended 

Complaint”), on September 18, 2020. The Amended Complaint asserts nine counts against 

Defendant: Count I – Negligent Hiring and Retention; Count II – Negligent Supervision and 

Training; Count III – Negligent Failure to Warn of Dangerous Conditions; Count IV – Negligent 

Design, Installation, and/or Approval of the Subject Area and the Vicinity; Count V – Negligence 

Against Defendant for the Acts of its Crewmembers Based on Vicarious Liability; Count VI –

Negligent Failure to Inspect, Clean, Maintain, Repair, Remedy, and/or Take Other Reasonable 

Measures for the Safety of Plaintiffs; Count VII – Vicarious Liability Against Defendant for the 

Negligence of the Ship’s Medical Staff; Count VIII – Apparent Agency as to Defendant for the 

Acts of the Ship’s Medical Staff; and Count IX – Assumption of Duty as to Defendant for the 

Negligence of the Ship’s Medical Staff. See generally ECF No. [8]. 

Defendant retained Tray Edmonds (“Mr. Edmonds”), Dr. Jonathan Gottlieb (“Dr. 

Gottlieb”), Dr. Richard Rauck (“Dr. Rauck”), and Dr. Joseph Fernandez (“Dr. Fernandez”) as 

expert witnesses. See ECF No. [107] at 1. Plaintiffs challenge all of the experts’ opinions. See ECF 

No. [92]. Plaintiffs retained Dr. Nicholas Suite (“Dr. Suite”) and Jeffery Hanson (“Mr. Hanson”)

as expert witnesses. See ECF Nos. [93], [94]. Defendant challenges both experts’ opinions. See

ECF Nos. [93], [94].

II. LEGAL STANDARD

Federal Rule of Evidence 702 governs the admissibility of expert testimony. When a party 

proffers the testimony of an expert under Rule 702, the party offering the expert testimony bears 

the burden of laying the proper foundation, and that party must demonstrate admissibility by a 

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 2 of 22
Case No. 20-cv-22783-BLOOM/Louis

preponderance of the evidence. See Rink v. Cheminova, Inc., 400 F.3d 1286, 1291-92 (11th Cir. 

2005); Allison v. McGhan Med. Corp., 184 F.3d 1300, 1306 (11th Cir. 1999). To determine 

whether expert testimony or any report prepared by an expert may be admitted, the court must 

engage in a three-part inquiry, which includes whether: (1) the expert is qualified to testify 

competently regarding the matters the expert intends to address; (2) the methodology by which the 

expert reaches his or her conclusions is sufficiently reliable; and (3) the testimony assists the trier 

of fact, through the application of scientific, technical, or specialized expertise, to understand the 

evidence or to determine a fact in issue. See City of Tuscaloosa v. Harcros Chems., Inc., 158 F.3d 

548, 562 (11th Cir. 1998) (citing Daubert v. Merrill Dow Pharmaceuticals, Inc., 509 U.S. 579, 

589 (1993)). The Court of Appeals for the Eleventh Circuit refers to each of these requirements as 

the “qualifications,” “reliability,” and “helpfulness” prongs. United States v. Frazier, 387 F.3d 

1244, 1260 (11th Cir. 2004). While some overlap exists among these requirements, the court must 

individually analyze each concept. See id.

As for the qualification prong, an expert may be qualified in the Eleventh Circuit “by 

knowledge, skill, experience, training, or education.” J.G. v. Carnival Corp., No. 12-21089-CIV, 

2013 WL 752697, at *3 (S.D. Fla. Feb. 27, 2013) (citing Furmanite Am., Inc. v. T.D. Williamson, 

506 F. Supp. 2d 1126, 1129 (M.D. Fla. 2007); Fed. R. Evid. 702). “An expert is not necessarily 

unqualified simply because [his] experience does not precisely match the matter at hand.” Id.

(citing Maiz v. Virani, 253 F.3d 641, 665 (11th Cir. 2001)). “[S]o long as the expert is minimally 

qualified, objections to the level of the expert’s expertise go to credibility and weight, not 

admissibility.” See Clena Invs., Inc. v. XL Specialty Ins. Co., 280 F.R.D. 653, 661 (S.D. Fla. 2012) 

(citing Kilpatrick v. Breg, Inc., No. 08-10052-CIV, 2009 WL 2058384, at *1 (S.D. Fla. Jun. 25, 

2009)). “After the district court undertakes a review of all of the relevant issues and of an expert’s 

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 3 of 22
Case No. 20-cv-22783-BLOOM/Louis

4

qualifications, the determination regarding qualification to testify rests within the district court’s 

discretion.” J.G., 2013 WL 752697, at *3 (citing Berdeaux v. Gamble Alden Life Ins. Co., 528 F.2d 

987, 990 (5th Cir. 1976)).1

Next, when determining whether an expert’s testimony is reliable, “the trial judge must 

assess whether the reasoning or methodology underlying the testimony is scientifically valid 

and . . . whether that reasoning or methodology properly can be applied to the facts in issue.” 

Frazier, 387 F.3d at 1261-62 (citation omitted) (quotation marks omitted). To make this 

determination, the district court typically examines: “(1) whether the expert’s theory can be and 

has been tested; (2) whether the theory has been subjected to peer review and publication; (3) the 

known or potential rate of error of the particular scientific technique; and (4) whether the technique 

is generally accepted in the scientific community.” Id. (citing Quiet Tech. DC-8, Inc. v. HurelDubois, UK Ltd., 326 F.3d 1333, 1341 (11th Cir. 2003)). The Eleventh Circuit has emphasized 

that the four factors above are not exhaustive, and a court may need to conduct an alternative 

analysis to evaluate the reliability of an expert opinion. See id. at 1262 (“These factors are 

illustrative, not exhaustive; not all of them will apply in every case, and in some cases other factors 

will be equally important in evaluating the reliability of proffered expert opinion.”). Consequently, 

trial judges are afforded “considerable leeway” in ascertaining whether a particular expert’s 

testimony is reliable. Id. at 1258 (citing Kumho Tire Co., 526 U.S. at 152).

The final element, helpfulness, turns on whether the proffered testimony “concern[s] 

matters that are beyond the understanding of the average lay person.” Edwards v. Shanley, 580 F. 

App’x 816, 823 (11th Cir. 2014) (quoting Frazier, 387 F.3d at 1262). “[A] trial court may exclude

In Bonner v. City of Prichard, 661 F.2d 1206, 1209 (11th Cir. 1981), the Eleventh Circuit adopted as 

binding precedent all decisions of the Court of Appeals for the Fifth Circuit rendered prior to October 1, 

1981.

Case No. 20-cv-22783-BLOOM/Louis

expert testimony that is ‘imprecise and unspecific,’ or whose factual basis is not adequately 

explained.” Id. (quoting Cook ex rel. Est. of Tessier v. Sheriff of Monroe Cnty., Fla., 402 F.3d 

1092, 1111 (11th Cir. 2005)). To be appropriate, a “fit” must exist between the offered opinion 

and the facts of the case. McDowell v. Brown, 392 F.3d 1283, 1299 (11th Cir. 2004) (citing 

Daubert, 509 U.S. at 591). “For example, there is no fit where a large analytical leap must be made 

between the facts and the opinion.” Id. (citing Gen. Elec. Co. v. Joiner, 522 U.S. 136 (1997)).

Under Daubert, a district court must take on the role of gatekeeper, but this role “is not 

intended to supplant the adversary system or the role of the jury.” Quiet Tech., 326 F.3d at 1341 

(citations omitted) (quotation marks omitted). Consistent with this function, the district court must 

“ensure that speculative, unreliable expert testimony does not reach the jury.” McCorvey v. Baxter 

Healthcare Corp., 298 F.3d 1253, 1256 (11th Cir. 2002). “[I]t is not the role of the district court 

to make ultimate conclusions as to the persuasiveness of the proffered evidence.” Quiet Tech., 326 

F.3d at 1341 (citations omitted) (quotation marks omitted). Thus, the district court cannot exclude 

an expert based on a belief that the expert lacks personal credibility. Rink, 400 F.3d at 1293 n.7. 

On the contrary, “vigorous cross-examination, presentation of contrary evidence, and 

careful instruction on the burden of proof are the traditional and appropriate means of attacking 

shaky but admissible evidence.” Quiet Tech., 326 F.3d at 1341 (quoting Daubert, 509 U.S. at 596). 

“Thus, ‘[o]n cross-examination, the opposing counsel is given the opportunity to ferret out the 

opinion’s weaknesses to ensure the jury properly evaluates the testimony’s weight and 

credibility.’” Vision I Homeowners Ass’n, Inc. v. Aspen Specialty Ins. Co., 674 F. Supp. 2d 1321, 

1325 (S.D. Fla. 2009) (quoting Jones v. Otis Elevator Co., 861 F.2d 655, 662 (11th Cir. 1988)). 

Ultimately, as noted, “a district court enjoys ‘considerable leeway’ in making” evidentiary 

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 5 of 22

determinations such as these. Cook ex rel. Est. of Tessier, 402 F.3d at 1103 (quoting Frazier, 387 

F.3d at 1258).

III. DISCUSSION

As an initial matter, the Parties do not dispute the experts’ qualifications. Based on a review 

of the expert reports, the Court determines that each expert is qualified to opine on the matters 

covered in his respective expert report. As such, the Court proceeds to address each expert’s 

reliability and helpfulness.

a. Plaintiffs’ Motion

i. Mr. Edmonds

Defendant retained Mr. Edmonds to testify about the subject elevator. See ECF No. [92-1] 

at 2. Plaintiffs argue that Mr. Edmonds’ opinions do not utilize a reliable methodology and will 

not be helpful for the jury. See ECF No. [92] at 3-12. Defendant argues that Mr. Edmonds uses a

reliable methodology and his opinions will assist the jury. See ECF No. [107] at 3-9. Although 

Plaintiffs’ Motion challenges Mr. Edmonds’ opinions by numbering them and grouping them 

together (i.e., first opinion; second, third, fourth, and fifth opinions; sixth, seventh, and eighth 

opinions; and ninth opinion), see ECF No. [92] at 5-11, the Court sees no need to analyze Mr. 

Edmonds’ opinions in separate groups. The opinions are not numbered in Mr. Edmonds’ expert 

report, some of the supposedly separate groups of opinions offer the same conclusion, and 

Plaintiffs’ arguments – namely, that the opinions are not based on reliable methodology and will 

not be helpful for the jury – apply to all groups of opinions. As such, the Court addresses Plaintiffs’ 

two main arguments in turn and identifies specific opinions only when it is necessary to do so.

Case No. 20-cv-22783-BLOOM/Louis

1. Reliability

Plaintiffs’ first general argument in regard to Mr. Edmonds’ expert testimony is that Mr. 

Edmonds does not use reliable methods to reach his conclusions and provides no explanation as to 

why the jury should believe his opinions. See ECF No. [92] at 5. Defendant argues that Mr. 

Edmonds explains in his expert report the materials and methods he relied on to form his opinions.

See ECF No. [107] at 3-8.

The Court agrees with Defendant that Mr. Edmonds used reliable methods. Mr. Edmonds’

expert report states that he reviewed case-specific materials, the CCTV footage, mathematical 

calculations regarding kinetic energy, a site inspection, and various standards and codes. See

generally ECF No. [92-1]. Mr. Edmonds states, after reviewing the CCTV footage, measurements 

taken during his site inspection, mathematical calculations of kinetic energy, and applicable safety 

codes, that the “door closing force and door closing kinetic energy” complied with pertinent codes 

at the time of the incident. See ECF No. [92-1] at 7. Mr. Edmonds further states that based on his 

review of Defendant’s Elevator Safety Requirements and maintenance documents, the elevator 

was properly maintained and inspected. See id. at 11. The Court considers such methods to be 

reliable in forming his opinions about the functioning and maintenance of the elevator at or around 

the time of the incident.

To the extent that Plaintiffs argue that Mr. Edmonds’ testimony should be not admitted

because Mr. Edmonds does not make clear the documents and tests he relies on and because the 

Certificate of Inspection from KONE is not dated, see ECF No. [92] at 9, 10-11, the Court is not 

persuaded. As Defendant corectly notes, Mr. Edmonds tested the elevator door by taking pertinent 

measurements and calculating the elevator door’s kinetic energy. See ECF No. [107] at 4 (citing 

ECF No. [92-1] at 19). Mr. Edmonds also notes the exact standards and codes he reviewed in 

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 7 of 22
Case No. 20-cv-22783-BLOOM/Louis

8

conjunction with his measurements to form his expert opinion. See ECF No. [92-1] at 4, 6. As 

such, Mr. Edmonds makes sufficiently clear the documents and tests on which he relies. Plaintiffs 

may, of course, explore any weaknesses in Mr. Edmonds’ documents and tests at crossexamination, but they are not grounds to exclude his opinions. See Pleasant Valley Biofuels, LLC 

v. Sanchez-Medina, No. 13-23046-CIV, 2014 WL 2855062, at *5 (S.D. Fla. June 23, 2014).

2

However, the Court is persuaded by Plaintiffs’ argument that Mr. Edmonds’ specific

opinion that a “small girl” broke the elevator panel when she pressed an elevator button with her 

elbow is not reliable. See ECF No. [92] at 6-8.3 Unlike his other opinions, Mr. Edmonds’ particular

opinion regarding the “small girl” appears to be based solely on his review of the CCTV footage.

See ECF No. [92-1] at 10 (“Based upon a review of the video showing the events surrounding this 

case, a small girl enters elevator #PL17 at or around 8:47:32 pm with an adult female. The girl 

utilizes an improper method to press a button (she used her elbow to jab the button instead of 

pressing the button with her finger) on the left car operating panel. Based upon the subsequent 

operation of the elevator doors, it appears the door close button was stuck in the ‘pressed’ 

position.” (emphasis added)). Mr. Edmonds did not review other materials or conduct any 

scientific tests to rule out other potential causes of the elevator malfunctioning. See ECF No. [92-

1] at 6, 10. In short, Mr. Edmonds’ opinion on this matter is pure speculation based solely on his 

view of the CCTV footage. His expert opinion on this issue is not based on reliable, scientifically 

2 Plaintiffs also argue that Mr. Edmonds’ site inspection over two years after the incident cannot be used to 

form his opinion of the incident in question. See ECF No. [92] at 9. The argument is unavailing. There is 

no evidence that the physical features of the elevator doors materially changed, and Mr. Edmonds can rely 

on his measurements of the elevator door two years after the incident to calculate kinetic energy. Further, 

since site inspections are routine parts of reliable methodology, Mr. Edmonds’ inspection the elevator door 

two years after the incident may be a part of his overall methodology.

3 Plaintiffs refer to the specific opinion as Mr. Edmonds’ second and fourth opinions. See ECF No. [92] at 

6-7.

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 8 of 22
Case No. 20-cv-22783-BLOOM/Louis

9

valid methodology. As such, Mr. Edmonds’ testimony on this matter is inadmissible. See Frazier, 

387 F.3d at 1261-62. The Court need not address Plaintiffs’ other arguments on this matter.

Plaintiffs also argue that Mr. Edmonds’ opinions should be limited to the time period 

depicted in the CCTV, especially since the opinions in his expert report pertain to that time period

only. See ECF No. [92] at 6. Defendant does not address this specific argument. See ECF No. [107] 

at 3-8. Plaintiffs’ argument on this issue is well-taken. See ECF No. [92] at 6. Mr. Edmonds does 

not appear to offer any testimony beyond the time period depicted in the CCTV. See generally 

ECF No. [92-1]. Therefore, Mr. Edmonds’ opinions will be limited to the time period depicted in 

the CCTV footage.4

2. Helpfulness

The Court now addresses whether Mr. Edmonds’ opinions, other than the inadmissible 

opinions noted above, are helpful. Plaintiffs argue that Mr. Edmonds’ opinions are not helpful for 

the jury because he merely reviews the CCTV footage. ECF No. [92] at 11-12. Defendant argues 

that Mr. Edmonds’ opinions are helpful because his opinions about the elevator doors’ kinetic 

energy and how it should be interpreted within the context of pertinent European Union elevator 

codes are beyond the understanding of the average lay person. See ECF No. [107] at 8-9. Defendant 

also argues that if the Court were to find inadmissible Mr. Edmonds’ review of the CCTV footage 

because the footage speaks for itself, then Plaintiffs’ expert’s testimony regarding the CCTV 

footage should be similarly inadmissible. See ECF No. [107] at 9.

The Court determines that Mr. Edmonds’ opinions – other than the inadmissible opinion 

about the “small girl” addressed above – rely not only on the CCTV footage but also on his analysis

of kinetic energy and his review of relevant codes. See ECF No. [92-1] at 10-11. The Court 

4 However, to be clear, Mr. Edmonds will be permitted to testify about his review of the inspections that 

took place before and after the incident as they were the bases for his opinions of the subject incident.

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 9 of 22
Case No. 20-cv-22783-BLOOM/Louis

10

considers such analysis to be beyond the understanding of the average lay person. As such, Mr. 

Edmonds may offer the opinions he formed partly relying on the CCTV footage. See Edwards, 

580 F. App’x at 823. However, in Jackson v. Catanzariti, No. 6:12-CV-113, 2019 WL 2098991, 

at *9 (S.D. Ga. May 14, 2019), the court found that an expert could not give a general overview 

of what a particular video showed without offering “expert gloss or explanation” because the jury 

could determine for itself the contents of the video. As such, Plaintiffs are persuasive to the extent 

that any testimony that merely provides an overview of the CCTV footage itself would not be 

helpful. In short, the CCTV footage speaks for itself and any testimony offering general 

observations of the CCTV footage is inadmissible, but Mr. Edmonds’ expert opinion based on the 

footage does not speak for itself and is admissible.

In sum, Mr. Edmonds will be permitted to offer his expert testimony on all matters in his 

expert report, except for (1) his opinion about the small girl breaking the elevator door, and (2) 

general observations of the CCTV footage.

ii. Dr. Gottlieb

Defendant retained Dr. Gottlieb to testify about Plaintiffs’ medical conditions. See 

generally ECF Nos. [92-3]; [107-1]. Dr. Gottlieb purports, among other things, that the cause of 

Plaintiff Kathryn Birren’s injuries is not the subject incident but a motor vehicle accident. See ECF 

No. [92-3] at 7.

1. Testimony about Mandy Birren

As a preliminary matter, Plaintiffs argue that Dr. Gottlieb should be prohibited from 

testifying about Plaintiff Mandy Birren because his expert report focuses only on Plaintiff Kathryn 

Birren. See ECF No. [92] at 13. Defendant responds that Dr. Gottlieb prepared a separate expert

report based upon his review of Plaintiff Mandy Birren’s medical records and physical 

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 10 of 22
Case No. 20-cv-22783-BLOOM/Louis

11

examination and that the report was properly produced to Plaintiffs. See ECF No. [107] at 9-10; 

see also ECF No. [107-1]. Plaintiffs state that Plaintiffs’ Counsel was not served the second expert

report but that they withdraw their objection for the purposes of the instant Motion. See ECF No. 

[110] at 5. Therefore, Dr. Gottlieb may testify regarding Plaintiff Mandy Birren’s medical 

condition.

2. Testimony about Kathryn Birren

Plaintiffs argue that Dr. Gottlieb should be prohibited from testifying about Plaintiff 

Kathryn Birren’s medical condition, including the cause of Plaintiff’s injury, because Dr. 

Gottlieb’s opinions are not based on reliable methodology and are not helpful for the jury. See 

ECF No. [92] at 12-14. Plaintiffs argue that Dr. Gottlieb’s opinions are not based on reliable 

methodology because Dr. Gottlieb admits that he does not have MRIs or any other images of 

Plaintiff Kathryn Birren’s cervical spine that are required to offer “definitive opinions on causality 

and the need for lumbar spine treatment[.]” Id. at 13 (citing ECF No. [92-3] at 7). Plaintiffs also 

argue that Dr. Gottlieb’s opinions are not helpful because he merely reviews the CCTV footage. 

See id. at 14. Defendant responds that Dr. Gottlieb states that his opinions are based on his 

experience as a board-certified orthopedic spine surgeon, combined with a “physical examination, 

review [of] medical records, and review [of] supporting documentation related to this incident.” 

ECF No. [107] at 11 (quoting ECF No. [92-3] at 4). 

The Court agrees with Defendant. First, in regard to reliability, although Plaintiffs claim 

that Dr. Gottlieb did not review relevant scans and images, Dr. Gottlieb’s report states that he 

reviewed several medical reports produced by other medical professionals that contained imaging 

reports. See ECF No. [92-1] at 3. It is well-established that experts can rely on the opinions of 

others in forming their opinions. See Daubert, 509 U.S. at 592; In re 3M Combat Arms Earplug 

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 11 of 22
Case No. 20-cv-22783-BLOOM/Louis

12

Prod. Liab. Litig., No. 3:19-md-2885, 2021 WL 765019, at *45 (N.D. Fla. Feb. 28, 2021) (finding 

that an expert’s opinion was admissible because it did not “simply parrot” another other expert’s

testimony).

5 Therefore, Dr. Gottlieb’s use of other medical professionals’ imaging reports is 

permissible and sufficiently reliable. In addition, although Plaintiffs argue that Dr. Gottlieb fails 

to explain how his review of the materials led to his conclusions, see ECF No. [92] at 13, Dr. 

Gottlieb’s report suggests otherwise, see ECF No. [92-3] at 7 (“Treatment rendered to the cervical 

spine following the subject incident through the occurrence of the motor vehicle accident was 

reasonable and necessitated by the subject accident. However, it is my opinion that the ultimate 

need for surgical treatment was not the September 7, 2019 incident. This opinion is based primarily 

on the provided medical records and the imaging reports.”). 

Further, to the extent that Plaintiffs argue inadmissibility because Dr. Gottlieb admits he 

cannot form a more definitive opinion and would have preferred to review MRI films himself, the 

Court is not persuaded. Dr. Gottlieb states that “prior to offering definitive opinions on causality 

and the need for lumbar spine treatment I would prefer to review the lumbar spine MRI[,]” ECF 

No. [92-3] at 7. However, he also states that “[t]he opinions expressed in this report are all within 

a reasonable degree of medical certainty and based on my personal assessment of the claimant and 

review of supporting documentation[,]” id. at 8. The Court considers such a statement to satisfy

the Daubert standard for reliability since Dr. Gottlieb clearly states that although he would have 

preferred to review additional evidence, the opinions he did express are within a reasonable degree 

of medical certainty. As noted above, it is also evident that Dr. Gottlieb reviewed pertinent medical 

5 As Defendant correctly points out, Plaintiffs’ representation that Dr. Gottlieb did not consult medical 

records from practitioners – other than records from a chiropractor – regarding Plaintiff Kathryn Birren’s 

lower back pain misconstrues Dr. Gottlieb’s expert report. See ECF No. [107] at 13. Other practitioners did 

not see Plaintiff Kathryn Birren regarding her lower back, and Dr. Gottlieb cannot consult nonexistent 

medical records. See id.

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 12 of 22
Case No. 20-cv-22783-BLOOM/Louis

13

records in forming his conclusion. See id. at 7. Therefore, Dr. Gottlieb’s stated preference to review 

the MRIs himself goes to the weight of the evidence, not its admissibility. Plaintiffs may crossexamine Dr. Gottlieb to the extent that he did not review the lumbar spine MRIs himself and 

instead relied on other medical experts’ review of the MRIs.

6

Next, in regard to helpfulness, although Dr. Gottlieb relies on CCTV footage, Dr. Gottlieb 

also relies on his analysis of extensive medical records as noted above. See ECF No. [92-3] at 7. 

As such, contrary to Plaintiffs’ argument that Dr. Gottlieb’s review of the CCTV footage involved 

“no scientific analysis whatsoever[,]” ECF No. [110] at 6-7, Dr. Gottlieb appears to have used the 

CCTV footage in conjunction with other medical records to conduct an expert medical diagnosis 

of the cause of Plaintiff Kathryn Birren’s injury. As before, the Court considers the use of CCTV 

footage in conjunction with other medical records and the resulting medical conclusions to go

beyond the expertise of the average lay person. As such, Dr. Gottlieb’s opinions will be helpful to 

the jury, and he may offer the opinions he formed partly relying on the CCTV footage. See

Edwards, 580 F. App’x at 823. However, as stated before, the Court agrees with Plaintiffs to the 

extent that any testimony that merely provides an overview of the CCTV footage itself would not 

be helpful. See Jackson, 2019 WL 2098991, at *9.

As such, all of Dr. Gottlieb’s opinions will be admissible, but Dr. Gottlieb will not be 

permitted to provide an overview of the CCTV footage, which speaks for itself.

iii. Dr. Rauck

Defendant retained Dr. Rauck to testify about Plaintiff Mandy Birren’s medical conditions. 

See generally ECF No. [92-4]. Dr. Rauck opinests that Plaintiff Mandy Birren’s alleged Amplified 

6 Plaintiffs’ argument that Dr. Gottlieb did not review photos or other materials from the car accident

similarly goes to the weight of Dr. Gottlieb’s opinion, not its admissibility. See ECF No. [110] at 5-6. 

Plaintiffs may cross-examine Dr. Gottlieb on whether he reviewed photos or other evidence from the car 

accident.

Case No. 20-cv-22783-BLOOM/Louis

14

Musculoskeletal Pain Syndrome (“AMPS”) was not caused by Plaintiff Kathryn Birren bumping 

into her and that Plaintiff Mandy Birren’s gymnastics and trampoline activities caused greater 

force on her back than the incident in question. See id. at 7.

1. Testimony about Kathryn Birren

As a preliminary matter, Plaintiffs argue that Dr. Rauck should be prohibited from 

testifying about Plaintiff Kathryn Birren. See ECF No. [92] at 16. Defendant agrees. See ECF No. 

[107] at 15. Therefore, Dr. Rauck may not testify regarding Plaintiff Kathryn Birren’s medical 

conditions.

2. Testimony about Mandy Birren

Plaintiffs argue that Dr. Rauck should be prohibited from testifying about Plaintiff Mandy

Birren’s alleged AMPS because Dr. Rauck’s opinions are not based on reliable methodology and 

will not be helpful for the jury. See ECF No. [92] at 16. Plaintiffs argue that Dr. Rauck’s 

methodology is not reliable because Dr. Rauck does not discuss how he arrived at his conclusions, 

admits that AMPS pathophysiology is “poorly understood,” and speculates that Plaintiff Mandy 

Birren’s gymnastics and trampoline activities exerted a greater force on her body than the incident 

in question. See id. at 16-17. Plaintiffs also argue that Dr. Rauck’s opinions, much like Dr. 

Gottlieb’s opinions, will not be helpful for the jury because he merely reviewed the CCTV footage. 

See id. at 18. Defendant responds that Dr. Rauck’s methodology is reliable because he reviewed

medical records reflecting Plaintiff Mandy Birren’s medical treatment since 2013, Plaintiff Mandy 

Birren’s deposition and interrogatories, and CCTV footage of the subject incident. See ECF No. 

[107] at 15-16. Defendant does not, however, address Plaintiffs’ claim that Dr. Rauck’s opinion 

will not be helpful. See generally id.

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 14 of 22
Case No. 20-cv-22783-BLOOM/Louis

15

In regard to reliability, the Court agrees with Defendant. As Defendant correctly notes, Dr. 

Rauck’s report expressly provides numbered paragraphs, each containing a conclusion and 

supporting rationale. See ECF No. [107] at 16 (citing ECF No. [92-4] at 6-7). Further, Dr. Rauck’s 

opinion regarding Plaintiff Mandy Birren’s gymnastic and trampoline activities is based Dr. 

Rauck’s review of an MRI and Plaintiff Mandy Birren’s medical history. See ECF No. [92-4] at 

7. Dr. Rauck also explains that trauma rarely causes AMPS, which supports his opinion that 

gymnastic and trampoline activities, rather than the trauma of colliding with Plaintiff Kathryn 

Birren, are the causes of Plaintiff Mandy Birren’s alleged AMPS. See id. at 6. Considering Dr. 

Rauck’s medical expertise and his review of Plaintiff Mandy Birren’s MRI and pertinent medical 

history, the Court determines that Dr. Rauck’s expert opinion on the causal effect of gymnastic 

and trampoline activities is reliable.

Further, the fact that Dr. Rauck states that AMPS is “poorly understood” does not render 

his methodology unreliable. As long as the methodology is reliable, expert testimony may be

admissible even if the medical condition itself is poorly understood. Here, Dr. Rauck’s expert 

testimony is based on a review of Mandy Birren’s medical records and his years of experience as 

a medical professional. See ECF No. [92-4] at 1. The Court considers such a methodology to be 

sufficiently reliable even if the medical condition is poorly understood generally.

7

Additionally, in regard to helpfulness, although Dr. Rauck relies on the CCTV footage, Dr. 

Rauck also relies on his analysis of extensive medical records, similar to Dr. Gottlieb’s partial 

reliance on the CCTV footage. See ECF No. [92-4] at 2, 7. As before, Dr. Rauck appears to have 

7 To the extent that Plaintiffs argue that Dr. Rauck offers no explanation for how he reached this conclusion 

that Plaintiff Mandy Birren’s treating physician, Dr. Trinidad, “is simply wrong[,]” see ECF No. [92] at 17 

(quoting ECF No. [92-4] at 7), the Court is not persuaded. Dr. Rauck explains that Dr. Trinidad is “simply 

wrong” because Dr. Trinidad made is conclusion without a physical exam and despite an MRI that shows 

no facet pathology. See ECF No. [92-4] at 7.

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 15 of 22
Case No. 20-cv-22783-BLOOM/Louis

16

used the CCTV footage in conjunction with the medical records to conduct a scientific analysis of 

the cause of Plaintiff Mandy Birren’s injury. See id. at 1. The Court again considers such medical 

analysis that only partly relies on the CCTV footage to be beyond the understanding of the average 

lay person and helpful for the jury. See Edwards, 580 F. App’x at 823. However, although Dr. 

Rauck’s medical opinions are admissible, for the same reasons stated above, Dr. Rauck is not 

permitted to give a general overview of the CCTV footage, which speaks for itself. See Jackson,

2019 WL 2098991, at *9.

In sum, Dr. Rauck’s testimony concerning Plaintiff Mandy Birren is admissible, but Dr. 

Rauck will not be permitted to give an overview of the CCTV footage.

8

iv. Dr. Fernandez

Defendant retained Dr. Fernandez as an orthopedic expert to testify about Plaintiff Kathryn 

Birren’s shoulder. See ECF No. [92-5]. Defendant states that Dr. Fernandez will serve as a rebuttal 

witness in the event that Plaintiff Kathryn Birren argues that she will require future treatment for

her right shoulder as a result of the subject incident. See ECF No. [107] at 17.

1. Testimony about Mandy Birren

As a preliminary matter, Plaintiffs argue that Dr. Fernandez should be prohibited from 

testifying about Plaintiff Mandy Birren. See ECF No. [92] at 19. Again, Defendant agrees. See 

ECF No. [107] at 18. Therefore, Dr. Fernandez may not testify regarding Mandy Birren’s medical 

condition.

8 To the extent that Plaintiffs contend that Dr. Rauck should not be permitted to testify about Plaintiff 

Mandy Birren’s eating disorder, the Court notes that Plaintiffs do not cite any part of Dr. Rauck’s report

that allegedly discusses Plaintiff Mandy Birren’s eating disorder. See ECF No. [92] at 16. Dr. Rauck’s 

testimony will be limited to his expert report.

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 16 of 22
Case No. 20-cv-22783-BLOOM/Louis

17

2. Testimony about Kathryn Birren

Plaintiffs argue that Dr. Fernandez should not be permitted to testify about Plaintiff 

Kathryn Birren’s medical conditions other than her right shoulder because his expert report is 

limited to the shoulder and because he offers no causation opinions. See ECF No. [92] at 19. 

Plaintiffs also argue that Dr. Fernandez’s opinion will not be helpful because he is a cumulative 

expert in light of Dr. Gottlieb who is also an orthopedic expert. See ECF No. [92] at 20. Defendant 

clarifies in its Response that Dr. Fernandez will only testify about Plaintiff Kathryn Birren’s 

shoulder. See ECF No. [107] at 17-18. Defendant also notes that Dr. Fernandez will not offer a 

causation opinion and only offer an opinion about the need for future treatment as a potential 

rebuttal witness. See id. at 18.

Based on Defendant’s characterization of Dr. Fernandez’s expert opinion, the Court agrees. 

Plaintiffs’ argument that Dr. Fernandez should not be permitted to testify about medical conditions 

other than Plaintiff Kathryn Birren’s shoulder is moot since Dr. Fernandez will only testify about

Plaintiff Kathryn Birren’s shoulder. Further, because Dr. Gottlieb’s testimony islimited to Plaintiff 

Kathryn Birren’s spine and Dr. Fernandez’s testimony is limited to Plaintiff Kathryn Birren’s 

shoulder, Dr. Fernandez is not a cumulative expert. 

In sum, Dr. Fernandez’s opinion regarding Plaintiff Kathryn Birren’s shoulder is

admissible in its entirety.

9

b. Defendant’s Motion to Strike Suite

The Court now addresses Defendant’s Motion to Strike Suite. Plaintiffs retained Dr. Suite 

to give his expert opinion on the causes of Plaintiff Kathryn Birren’s injuries. See ECF No. [93-1] 

9 Plaintiffs argue that Dr. Fernandez should not be permitted to refer to Plaintiff Kathryn Birren as his

“patient” because there is no doctor patient relationship between Plaintiff Kathryn Birren and Dr. 

Fernandez. See ECF No. [92] at 19. That argument is well-taken. Dr. Fernandez shall not be permitted to 

refer to Plaintiff Kathryn Birren as his patient.

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 17 of 22
Case No. 20-cv-22783-BLOOM/Louis

18

at 4. Defendant argues that Dr. Suite’s methodology is not reliable because Dr. Suite only 

conducted a telemedicine examination. See ECF No. [93] at 4-5. Defendant emphasizes that Dr. 

Suite admitted that if he had conducted a physical examination, he “would better be able to opine 

on future costs, reasonableness, specific causation, and whether all bills are related and necessary. 

A telemedicine examination alone and review of records is not able to fulfill all of the elements of 

an in-person examination.” Id. at 5 (quoting ECF No. [93-1] at 4). Based on Dr. Suite’s own 

admission, Defendant argues that Dr. Suite was unable to confirm his own impressions and his 

opinions are speculative. See id. at 7. Defendant also argues that Dr. Suite has not provided specific 

opinions regarding future treatment, future costs, and reasonableness of medical bills, and his

testimony on those matters should be inadmissible. See ECF No. [112] at 2.

Plaintiffs concede that Dr. Suite did not conduct an in-person examination but argue that 

Dr. Suite reviewed Plaintiff Kathryn Birren’s medical records, CCTV footage of the incident, 

films, MRI scans, testimony, and other evidence, in addition to the telemedicine examination. See 

ECF No. [102] at 8. As such, Plaintiffs argue that Dr. Suite’s methodology is reliable. See id. 

Plaintiffs also note that even if the telemedicine evaluation did not take place, the court in Geyer 

v. NCL (Bahamas) Ltd., 203 F. Supp. 3d 1212 (S.D. Fla. 2016), found that the lack of a medical 

examination did not necessarily render an expert medical opinion inadmissible under Daubert. See 

ECF No. [102] at 10. 

The Court agrees with Plaintiffs to the extent that Dr. Suite’s causation opinion is based on 

reliable methodology. Dr. Suite’s expert report clearly describes his review of medical records, 

CCTV footage of the incident, and other evidence. See ECF No. [93-1] at 3-4. In addition, although

Defendant takes issue with Dr. Suite’s admission that he would be better able to discuss aspects of 

his opinions after an in-person physical examination, the Court notes that Dr. Suite did not 

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 18 of 22
Case No. 20-cv-22783-BLOOM/Louis

19

affirmatively state that the lack of an in-person physical examination prevented him forming a

reliable opinion. Rather, even though Dr. Suite conceded that a telemedicine examination does not

fulfill all of the elements of an in-person examination, he nonetheless formed his conclusions 

regarding the cause of the injuries “within a reasonable degree of medical probability.” ECF No. 

[93-1] at 4. Given that experts may rely on a review of medical records alone, without an

examination of any type, to form expert medical opinions regarding causation, the Court considers 

Dr. Suite’s methodology to be sufficiently reliable. See Geyer, 203 F. Supp. 3d 1212. Put 

differently, a telemedicine examination may not fulfill all of the elements of an in-person 

examination but it does not render such examinations to be inherently unreliable, especially when 

telemedicine examinations are used in conjunction with other medical records. Defendant’s 

arguments regarding the use of telemedicine and Dr. Suite’s express preference for an in-person

physical examination are more appropriate for cross-examination and are not proper grounds to 

strike Dr. Suite’s causation opinion.

However, Defendant correctly points out that Dr. Suite does not elaborate on his opinions 

regarding future treatment, future costs, and reasonableness of medical bills in his expert report. 

See ECF No. [112] at 2; see generally ECF No. [93-1]. Dr. Suite states in his expert report that 

“[s]he is going to need further care and treatment to manage her symptomatology.” Id. at 4. Dr. 

Suite, however, does not offer the precise treatment needed, dollar figure estimates of the future 

costs, or reasonableness of any medical bills. As such, any expert testimony on such matters would 

go beyond the scope of Dr. Suite’s expert report and is inadmissible.

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 19 of 22
Case No. 20-cv-22783-BLOOM/Louis

20

In sum, Dr. Suite will be permitted to testify about medical causation, but Dr. Suite will 

not be permitted to testify about future treatment, future costs, and medical bills.10

c. Defendant’s Motion to Strike Hanson

The Court now addresses Defendant’s Motion to Strike Hanson. Plaintiffs retained Mr. 

Hanson to testify about the elevator. See ECF No. [94-1] at 3-6. Defendant argues that Mr. 

Hanson’s opinions regarding the inadequate maintenance of the subject elevator are unreliable (or 

unexplained) because Mr. Hanson only reviewed materials relating to events that took place after 

the subject incident, which shed no light on the subject incident. See ECF No. [94] at 4. Defendant 

further argues that Mr. Hanson’s opinions are not helpful to the jury because he merely offers his 

own interpretation of the CCTV footage. See id. at 4-6. Plaintiffs respond that Mr. Hanson’s 

methodology is reliable because Mr. Hanson conducted a site inspection and reviewed various 

elevator inspections. See ECF No. [101] at 11-13. Although Plaintiffs do not specifically address 

Defendant’s contention regarding the helpfulness of Mr. Hanson’s overview of the CCTV footage, 

Plaintiffs generally argue that Mr. Hanson’s opinions will be helpful for the jury. See id. at 13-14.

The Court agrees with Plaintiffs. Mr. Hanson’s expert report contains a lengthy discussion 

of his methodology, which includes a review of inspection reports from shortly before the subject 

incident, industry code, and CCTV footage. See ECF No. [101] at 6 (quoting excerpts from Mr. 

Hanson’s expert report in which Mr. Hanson notes that he reviewed maintenance checklists from 

before the incident). The Court considers the review of such materials, combined with Mr. 

Hanson’s expertise, to be sufficiently reliable in forming Mr. Hanson’s opinions regarding the 

maintenance of the elevator. Further, Mr. Hanson’s opinions are helpful because they only partly 

10 Plaintiffs request a Daubert hearing in regard to Dr. Suite. See ECF No. [102] at 11-12. The Court does 

not find a hearing to be necessary to resolve the issues presented in the pleadings. As such, the Court denies 

Plaintiffs’ request for a hearing.

Case 1:20-cv-22783-BB Document 119 Entered on FLSD Docket 02/14/2022 Page 20 of 22

21

rely on the CCTV footage and also rely on other relevant materials. As noted above, opinions 

partly relying on the CCTV footage in conjunction with other materials are helpful to the jury and 

admissible. See Edwards, 580 F. App’x at 823. However, similar to several aforementioned 

experts, Mr. Hanson will not be permitted to give a general overview of the CCTV footage itself 

since the CCTV footage speaks for itself. 11

In sum, Mr. Hanson will be permitted to offer his expert opinion, but he will not be 

permitted to provide an overview of the CCTV footage.

12

IV. CONCLUSION

Accordingly, it is ORDERED AND ADJUDGED as follows:

1. Plaintiffs’ Motion, ECF No. [92], is GRANTED IN PART AND DENIED IN 

PART. 

2. Defendant’s Motion to Strike Suite, ECF No. [93], is GRANTED IN PART 

AND DENIED IN PART.

3. Defendant’s Motion to Strike Hanson, ECF No. [94], is GRANTED IN PART 

AND DENIED IN PART.

11 Defendant references Umana-Fowler v. NCL (Bahamas) Ltd., which established that while “[a]n expert 

may testify as to his opinions on an ultimate issue of fact . . . he may not testify as to his opinion regarding 

ultimate legal conclusions.” ECF No. [94] at 5 (quoting 49 F.Supp.3d 1120, 1122 (S.D. Fla. 2014) (internal 

quotation marks and citation omitted)). Defendant, however, fails to identify which opinion reaches 

ultimate legal conclusions. See id. To the extent that any of Mr. Hanson opinions reach an ultimate issue, 

Plaintiffs argue that Mr. Hanson’s opinions are nonetheless admissible because they will be helpful to the 

jury. See ECF No. [101] at 14. Because Defendant does not specify which opinion reaches an ultimate issue, 

Defendant’s argument is unpersuasive. To the extent that Defendant is arguing that Mr. Hanson’s review 

of the CCTV footage speaks for itself, the Court is persuaded for the reasons stated above.

12 Plaintiffs request a Daubert hearing in regard to Dr. Hanson as well. See ECF No. [101] at 14-15. The 

Court does not find a hearing to be necessary to resolve the issues presented in the pleadings. As such, the 

Court denies Plaintiffs’ request for a hearing.
