Motion's Board of Directors' Reasons for Approval of the Business Combination,
page 114

2.       We note your revised disclosure in response to prior comment 19 and
reissue it in part.
         We note your disclosure on page 110 that Motion's management had
several calls with
         Barclays to validate and modify the proposed set of publicly listed
comparable companies
         that was initially provided by DocGo. We also note your disclosure
here that in valuing
         DocGo's business, Motion's Board gave considerable weight to the
valuations experienced
         by comparable publicly traded companies in the telehealth and
associated sectors of the
         healthcare industry. Please revise your disclosure to disclose the set
of comparable
         publicly traded companies initially provided by DocGo and discuss the
rationale for
         modifying such list, including the reasons any companies were excluded
or additional
         companies included in the modified list.
Background of the Proposed Transaction
Certain Forecasted Financial Information for DocGo, page 117

3.       The revised disclosure provided in response to prior comment 20
addresses changes that
         have occurred since the forecasts were developed for the Mobile Health
segment. Revise
         this disclosure to also address any changes that have affected the
Transportation Services
         segment.
4.       Disclosure on page 118 states that the revenues from leased hour
contracts will be driven
         by the number of markets in which DocGo operates and how successful
DocGo is in
         obtaining such contracts. Clarify the assumptions that were used to
derive the projections
         for revenues from leased hour contracts.
U.S. Federal Income Tax Considerations, page 145

5.       We note your response to prior comment 38 and reissue the comment in
part. Please
         revise your disclosure to clearly express an opinion on the tax
treatment of the merger and
         the related transactions. If the merger is not taxable to
shareholders, please also file a tax
         opinion with your registration statement. If there is uncertainty
regarding the tax
         treatment, counsel may issue a "should" or "more likely than not"
opinion to make clear
         that the opinion is subject to a degree of uncertainty, and explain
why it cannot give a firm
         opinion. In that regard, we note that Section 1.14 of the merger
agreement provides that
         the parties intend that the merger qualifies as a "reorganization"
within the meaning of
         Section 368(a) of the Code and your revised disclosure on page 147
that the parties have
         agreed to report the merger in a manner consistent with such tax
treatment so that the
         merger may qualify as a "reorganization" within the meaning of Section
368 of the Code.
         Refer to Item 601(b)(8) of Regulation S-K.

6.    Based on the revised disclosure in response to prior comment 36, it is
not clear what
      supporting factors you believe are relevant in explaining differences
between the values of
      recently granted stock-based awards compared to the fair value implied by
the proposed
      business combination. Provide us with a more comprehensive explanation of
the factors
      you believe support these differences. In addition, provide us with
information necessary
      to compare the weighted average grant date fair value per share for stock
options granted
      during the periods ended June 30, 2021 and December 31, 2020 to their
equivalent fair
      value as implied by the proposed business combination.
7.    It does not appear that the expanded disclosure in response to prior
comment 37
      adequately describes the nature of the material assumptions used to
calculate the fair value
      of DocGo   s stock-based awards. Please revise to provide this type of
information.

8.    We note the disclosure added in response to prior comment 45 indicating
that all
      transaction prices are fixed and determinable. We also note the
accounting policy
      description retains the disclosure regarding estimated contractual
allowances for claims
      subject to contracts with responsible paying entities. Please revise your
disclosure further
      to provide a clearer explanation of the nature of these contractual
allowances based on
      their typical characterization in DocGo   s contracts with its customers.
