       Notes to Financial Statements
       2. Summary of Significant Accounting Policy
       Goodwill, page 15

   1.                                                   We have read your
response to prior comment five and your disclosure that you operate
                                                        under one reporting
unit because all your business components have similar economic
                                                        characteristics and are
managed on an aggregated basis. Please more fully explain to us
                                                        what your business
components are and how you determined they all have similar
                                                        economic
characteristics. In this regard, please specifically address the fact that the
fair
                                                        values related to
various contingent earn-out liabilities appear to change in disparate
                                                        directions and the fact
that, based on your disclosures of pro forma and historical revenue

         amounts in note 10, the results of acquisitions appear to be
dissimilar, for example, it
         appears to us that revenues related to Healing Solutions declined by
approximately 50% in
         the current interim period relative to the comparative interim period.
10. Acqusition, page 28

2.       We have read your response to prior comment seven and appreciate the
additional
         information you provided; however, we note your acquisitions did not
include employees,
         access to organized workforces, or manufacturing
capabilities/facilities. Please more fully
         explain to us the specific acquired process or group of processes you
obtained and how
         you determined they cannot be replaced without significant cost,
effort, or delay.

3.       We have read your response to prior comment three and note the
revisions you included in
         your 9/30/21 Form 10-Q related to the non-GAAP financial measure,
Contribution
         Margin. Please tell us and revise future disclosures related to this
measure to more fully
         address the following:
             Explain how management uses the measure.
             Explain the purpose of the measure.
             Explain the specific nature of each adjustment to the measure,
including the reasons
             for each adjustment. For example, explain how you determined what
selling and
             distribution expenses to exclude from the measure, explain why you
believe
             excluding those expenses from a non-GAAP gross profit measure is
meaningful and
             appropriate, explain how you determined what selling and
distribution expenses and
             other operating expenses to not reflect in the measure, and
explain why you believe
             that is meaningful and appropriate.
             Tell us why you revised the proposed reconciliation you provided
in your response
             letter compared to the reconciliation you included in your Form
10-Q.

        You may contact Andi Carpenter at 202-551-3645 or Anne McConnell at
