American Chiropractic Association
The American Chiropractic Association (ACA) is the largest professional chiropractic organization in the United States. ACA attracts the most principled and accomplished chiropractors, who understand that it takes more to be called an ACA chiropractor.
We are leading our profession in the most constructive and far-reaching ways -- by working hand in hand with other health care professionals, by lobbying for pro-chiropractic legislation and policies, by supporting meaningful research and by using that research to inform our treatment practices.
We also provide professional and educational opportunities for all our members and are committed to being a positive and unifying force for the practice of modern chiropractic.
