About Us

With more than 4,000 members and over 12,500 physicians in the county, King County Medical Society (KCMS) is among the largest county medical societies in the United States. KCMS represents the collective voice of its member physicians who practice in King County – Washington state’s largest and most urban county. KCMS (established in 1888) supports physicians and works to improve the quality of life for doctors and their patients by promoting the highest ideals and standards of medical practice.

While the Society’s activities have evolved in response to advances and challenges in health care delivery, its core mission has remained the same:

To be a powerful voice and political advocate for physicians and patients at local, state, and federal levels.

The Society acts as a champion for King County doctors to support and strengthen the physician-patient relationship and promote the health and welfare of King County residents.
