Regional Medical Officer – Western Region
Dr. Cassidy Tsay - InnovAge Regional Medical Officer – Western Region

My parents often boasted that they were blessed with kids in the medical industry to help them maneuver through the complexity of healthcare. Under the PACE program, every participant has a “family” support team - which is exactly why I joined InnovAge.

Dr. Tsay is an internist with both medical practice and administrative experience. She recently was the chief medical officer of Prospect Medical Systems, a management service organization providing administrative support to individual physicians and medical groups caring for over 200,000 commercial, Medical Advantage, and Medicaid HMO members in Southern California. She has also worked for America’s Physician Groups, the leading U.S. trade association for accountable physician organizations, Blue Shield of California, and an independent physician association group.
Dr. Tsay received her medical degree from Albert Einstein College of Medicine in the Bronx, New York, and completed her internal medicine residency at the University of California, Irvine (UCI). She also holds a master’s degree in business administration from the UCI Paul Merage School of Business.
