Creating and accredited wellness coach course

At the Three Oaks Academy & Integrative Therapy Clinic we re currently training applicants to become body workers/massage therapists certified by the NCBTMB enabling them to apply for licensure throughout the U.S.A. Our aim is to further their postgraduate education by training them to become wellness coaches in order to advise clients on stress reduction and nutrition choices as these are often factors influencing overall health, including myofascial symptoms. How do we create a course that will have national certification/accreditation? Thank you, Don MacDonagh
