The mission of the Oklahoma Osteopathic Association (OOA) is to advocate for the osteopathic profession and promote the health and well-being of all Oklahomans. The OOA was founded in 1900 as an Oklahoma corporation and a true voluntary professional association. With more than 116 years of history, the OOA is the ONLY osteopathic entity in Oklahoma that represents all osteopathic physicians without regard to location, school or professional specialty.
