EXHIBIT 31.1
   1.
    
    I have reviewed this annual report on Form 10-K of MiMedx Group, Inc.;
 2.
    
    Based on my knowledge, this annual report does not contain any untrue
statement of a material fact or omit to state a material fact
necessary to make the statements made, in light of the circumstances
under which such statements were made, not misleading with respect to
the period covered by this annual report;
 3.
    
    Based on my knowledge, the financial statements, and other financial
information included in this annual report, fairly present in all
material respects the financial condition, results of operations and
cash flows of the registrant as of, and for, the periods presented in
this annual report;
 4.
    
    The registrants other certifying officer and I are responsible for
establishing and maintaining disclosure controls and procedures (as
defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal
control over financial reporting (as defined in the Exchange Act Rules
13a-15(f) and 15d-15(f)) for the registrant and have:
 (a)
    
    designed such disclosure controls and procedures, or caused
such disclosure controls and procedures to be designed under our
supervision, to ensure that material information relating to the
registrant, including its consolidated subsidiaries, is made known
to us by others within those entities, particularly during the
period in which this annual report is being prepared,
 (b)
    
    designed such internal control over financial reporting, or
caused such internal control over financial reporting to be
designed under our supervision, to provide reasonable assurance
regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in
accordance with generally accepted accounting principles,
 (c)
    
    evaluated the effectiveness of the registrants disclosure
controls and procedures and presented in this report our
conclusions about the effectiveness of the disclosure controls and
procedures, as of the end of the period covered by this annual
report based on such evaluation, and
 (d)
    
    disclosed in this annual report any change in the registrants
internal control over financial reporting that occurred during the
registrants last fiscal quarter that has materially affected, or
is reasonably likely to materially affect, the registrants
internal control over financial reporting; and
 5.
    
    The registrants other certifying officer and I have disclosed, based
on our most recent evaluation of internal control over financial
reporting, to the registrants auditors and the audit committee of the
registrants board of directors (or persons performing the equivalent
function):
 (a)
    
    all significant deficiencies and material weaknesses in the
design or operation of internal control over financial reporting
which are reasonably likely to adversely affect the registrants
ability to record, process, summarize and report financial
information; and
 (b)
    
    any fraud, whether or not material, that involves management or
other employees who have a significant role in the registrants
internal control over financial reporting.
