________________________ Appeal from the United States District Court for the Northern District of Georgia

________________________ (September 29, 2021) Before WILLIAM PRYOR, Chief Judge , JORDAN and GRANT , Circuit Judges.
PE R CURIAM:

USCA11 Case: 21-10541 Date Filed: 09/29/2021 Page: 1 of 52 Aiesha Callahan appeals pro se the summary judgment in favor of Emory Healthcare Inc. , and against her amended c omplain t that Emory violat ed the Family and Medical Leave Act, 29 U.S.C. § 2601 , and the Americans with Disabilities Act of 1990, 42 U.S.C. §§ 12112(a), 12203(a)

. Callahan complained that Emory violated the Leave Act by interfer ing with her use of medical leave and by retaliat ing against her for taking leave when it delay ed re assign ing her to a comparable position and that Emor y violated the Disabilities Act by discriminat ing against her in her reassignment and by retaliat ing against her for requesting an accommodation

. The district court ruled that Callahan a bandoned her c laims under the Leave Act and that she failed to establi sh a prima facie case of discrimination

or of retaliation under the Disabilities Act. We affirm.
We review de novo a summary judgment , and we vie w the record in the light most favorable to the non

- moving party. Weeks v. Harden Mfg. Corp. , 291 F.3d 1307, 1311 (11th Cir. 2002). S ummary judgment is appropriate when there exists no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law

. Fed. R. Civ. P. 56(a)

. The district court correctly treated as abandoned Callahan’s c laim s of interference and retaliation under the Leave Act. “[G]rounds alleged in the complaint but not relied upon in summary judgment are deemed abandoned.” Solutia, Inc. v. McWane, Inc. , 672 F.3d 1230, 1239 (11th Cir. 2012) (quoting

USCA11 Case: 21-10541 Date Filed: 09/29/2021 Page: 2 of 53 Resolution Trust Corp. v. Dunmar Corp. , 43 F.3d 587, 598 (11th Cir. 1995))

. Callahan mov ed for summary judgment based on ly on her claims under the Disabilities Act. A nd af ter Emory move d for summary judgment, it bec a me

“ incumbent upon [Callahan] to respond by, at the very least, raising in [ her ] opposition papers any and all arguments or defenses [s he ] felt precluded judgment
in [its] favor.” Case v. Eslinger , 555 F.3d 1317, 1329 (11th Cir. 2009) ( internal quotation marks omitted and al terations adopted ). But Callahan failed to r espon d with any argument that Emory violated the Leave Act. The district court did not err by entering summary judgment against Callahan’s complaint that Emory violated the Disabilities Act. Callahan failed to establish a prima facie case of discrimination by failing to prove that Emory refused to reasonably accommodate her disabilities , and she failed to establish a prima facie case of retaliation by failing to prove tha t Emory took an adverse action against her

. See Lucas v. W.W. Grainger, Inc. , 257 F.3d 1249, 12 55, 1260 (11th Cir. 2001)

. Emory accommodat ed Callahan’s anxiety and post

- traumatic stress disorders. A fter Callahan took medical leave and requested a transfer from her position as a patient liaison in the emergency department to a “less stressful environment,” Emory assigned Callahan an in

- house recruiter and retained her as an employee so she could exhaust her accrued leave with pay and compete with
ot her internal applicants for job openings. A human resources officer invit ed

USCA11 Case: 21-10541 Date Filed: 09/29/2021 Page: 3 of 54 Callahan to interview for a comparable job , which she rej e cte d , and within a couple of weeks found her a comparable position as a visitor and outpatient liaison with identical pay , which she accepted. Callahan’s supervisors also g ranted her request for a mentor and advised her how to interact with coworkers, including a security officer she disliked. After Callahan disparaged the officer and inappropriately advised clinicians how to care for their patient s , her supervisors
gave her a written warning, but i t had no “ tangible, negative effect on [ her ] employment ” because an other company officer later res cinded the warning. See id.
at 1261. T he warning too was unrelated to Callahan’s medical conditions

. Callahan’s supervisors testified and she conceded that they were unaware of her medical conditions and disciplined her for her misconduct with coworkers. Callahan argues that Emory “ discriminated against her by failing to hire her for all [the] jobs she applied for, ” but Callahan alleg ed in her c omplaint that Emory violated the Disabilities Act by delay ing her return to work. W e cannot consider a failure

- to

- hire claim that Callahan failed to develop in the district court. See Access Now, Inc. v. Sw. Airlines Co. , 385 F.3d 1324, 1331 (11th Cir. 2004) (“ This Court has repeatedly held that an issue not raised in the district court and raised for the first time in an appeal will not be considered by this court.” ). And Callahan could not amend her complaint to add a claim by alluding to “forty

- two co unts of failure to hire” in her opposition to Emory’s motion for summary judgment. See Gilmour

USCA11 Case: 21-10541 Date Filed: 09/29/2021 Page: 4 of 55 v. Gates, McDonald & Co. , 382 F.3d 1312, 1315 (11th Cir. 2004) (“ A plaintiff may not amend her complaint through argument in a brief opposing summary judgment .” )

. We AFFIRM the summary judgment in favor of Emory Healthcare. USCA11 Case: 21-10541 Date Filed: 09/29/2021 Page: 5 of 5
