The US Army Center for Health Promotion & Preventive Medicine recognizes the CHMM as a USACHPPM Professional Certification.  The US National Park Service requires supervision by a CHMM in many of their requests for proposal. Contracts that include the CHMM credential have also been issued by the US Air Force, the US EPA, the US Army Corps of Engineers, the Department of Veterans Affairs, the FDIC, and other Federal and state agencies.
