History

Prospect Medical Systems (now called Prospect Health) was formed in 1986 - thanks to a small group of physicians in northern Orange County who shared a passion for delivering quality healthcare. What was true years ago remains just as true today: Prospect places an emphasis on delivering exceptional medical care, helps members get maximum value from their insurance coverage, and offers exclusive services to its members.

Established in 1995, Prospect Medical Systems, the group's management service organization, was created to develop, implement, and manage a full range of services designed to simplify the relationship between doctor and patient. The following year, Prospect Medical Holdings was formed as the parent company of Prospect Medical Systems.

In July of 2025, Prospect Health was successfully acquired by Astrana Health. Together, we now support more than 20,000 providers serving over 1.6 million patients in value-based care arrangements across the country.
