The Philadelphia County Medical Society (PCMS) has been representing physicians for more than 160 years as they treat patients, advance science, maintain the standards of the profession, and protect the public health. The Society, a professional membership organization for physicians who live or work in the City of Philadelphia, has a tradition of activism on behalf of practitioners and patients. PCMS provides a common ground for physicians across a range of specialties to discuss health care issues of the day and work for the good of the profession and the public.

Today, its members continue to present the opinions of physicians before legislators and government officials, to protect the public health, and to keep physicians informed on the issues that affect their practice of medicine in Philadelphia.
