A portion of ACFAS member dues is allocated for Region activities. Regions use these funds to further the goals of ACFAS at the state and local level and to promote the superior care of foot and ankle surgical patients through education, research and promotion of the highest professional standards. Regions also work on outreach to students and residents, helping to give them a successful start in their careers as foot and ankle surgeons.

Regions are affiliate organizations of the American College of Foot and Ankle Surgeons. They are granted a charter and license to use the ACFAS name and logo, are mandated by their own articles of incorporation and bylaws, and remain separate entities from the parent organization.

For more information about Region activities, please contact Michelle Kennedy, ACFAS Director of Membership and Post Graduate Affairs.
