Established in 1915 by Dr. Heinrich Stern, the American College of Physicians is a national organization of internists—doctors who apply scientific knowledge and clinical expertise to the diagnosis, treatment and care of adults. With more than 140,000 members, it is the largest medical-specialty organization in the United States. The national headquarters is located in Philadelphia, and the organization acts locally through its many chapters and regions across the United States and abroad.
The American College of Physicians establishes and promotes clinical standards for the field, serves as the leading education and information resource for internists, advocates on public policy related to health care and conducts research to enhance quality of care. In addition, the organization releases four regular publications including the peer-reviewed Annals of Internal Medicine
. Through meetings and online education, internists can earn and maintain clinical certification. Additionally, medical students and residents can find mentorship, identify career paths and obtain career counseling and support.
