Arlington, Va. — The American Chiropractic Association (ACA) State Affiliate Program recently expanded with the addition of the Maine Chiropractic Association and the Oregon Chiropractic Association, bringing the total number of ACA state affiliates to 15. Membership in the Affiliate Program affords chiropractic state groups the opportunity to work more closely with ACA on issues that advance the chiropractic profession. Affiliate states maintain their own separate governance but benefit by having a representative seated in the ACA House of Delegates, giving them the ability to vote and help shape ACA policy. “We are excited to welcome the Maine and Oregon associations to the ACA Affiliate Program,” said John Falardeau, ACA senior vice president of public policy and advocacy.
