Most osteopathic physicians do not belong to unions, but some may be represented by the Doctors Council SEIU and the Union of American Physicians and Dentists. The American Association of Colleges of Osteopathic Medicine (AACOM) publishes the Osteopathic Medical College Information Book, which provides a listing of colleges with D.O. programs along with tuition and fees. The American Osteopathic Association is the major professional association for osteopathic physicians.
