About Us


The Sierra Sacramento Valley Medical Society is dedicated to bringing together physicians from all modes of practice to promote the art and science of quality medical care and to enhance the physical and mental health of our entire community.

In continuous operation since 1868, SSVMS is the oldest medical society in California and represents over 3,600 physicians in El Dorado, Sacramento and Yolo counties. 2018 marks our 150th anniversay. SSVMS is a component medical society of the California Medical Association (CMA).

In 1947 SSVMS founded the Sacramento Medical Foundation, now known as BloodSource. The community rallied behind the need to establish a blood supply for the area's growing population and the city of Sacramento provided a site. All members in good standing at SSVMS are automatically a member of BloodSource.
