Governing Board

NAFC was established by a group of forward-thinking fitness professionals, representing expertise in fields of Exercise Physiology, Adaptive Physical Education, Medicine, Nursing, and professional Lifestyles and Nutrition Coaching. Their desire was to enhance current fitness certification standards by providing access to a convenient, comprehensive, yet practical and affordable fitness education. The Governing Board is comprised of individuals who are assets to NAFC due to their various backgrounds and expertise. They advise, govern, and oversee the policies and direction of the organization.

The Board will at all times be comprised of at least a President, Vice President, Secretary and Treasurer. The Board is comprised of the founding members of NAFC, and members of the administrative staff who jointly oversee the activities of NAFC with the collective goal to carry forth the mission of our organization to the general public.

NAFC has established a structure to ensure appropriate stakeholder involvement by clearly defining responsibilities and boundaries respective to each position within NAFC governance regarding the representative positions held by members of the governing body. This consortium rotates on an annual basis for the assurance of the balance of the program.

As an independent and autonomous organization, NAFC will not permit any individual to participate on the governing board if they are stakeholders in any other fitness certifying organization thus ensuring no inappropriate influence by any outside body.
