From California to Rhode Island: Our Hospitals Provide Quality Care Close to Home
Prospect Medical Holdings, Inc., (Prospect Medical) established in 1996, is a healthcare services company emphasizing coordination of care and population health management, with a focus on preventive care.
Prospect Medical Holdings' facilities help coordinate quality care for patients through integrated networks of primary and specialty physicians, in affiliation with hospitals, clinics, other community-based providers and health plans.
We own a family of hospitals in four states that include tertiary medical centers, academic teaching hospitals, behavioral health facilities, community hospitals, and long-term care facilities. Our hospitals serve diverse, often underserved communities in Southern California, Connecticut, and Rhode Island.
All of our facilities provide a comprehensive range of services tailored to their specific communities, including partnerships with other area hospitals, physicians, and health plans. We pride ourselves on making investments in local hospitals and communities, creating new jobs, and expanding programs and services to improve care access and quality.
Historical Perspective
Our hospital story begins with the founding of Alta Hospitals System, LLC, in 1998 with a core mission to provide quality, compassionate, and accessible healthcare in Los Angeles and Orange counties. Alta operated a network of three acute care hospitals in Los Angeles, Norwalk, and Hollywood (pictured left), as well as a behavioral health facility in Van Nuys, with a combined 339 licensed beds.
In 2007, Prospect Medical Holdings acquired Alta with an enhanced vision for the future that revolves around a “Coordinated Regional Care” model. From a patient’s perspective, Coordinated Regional Care serves as a way out of the confusing healthcare maze. Instead of keeping physicians, hospitals, and health plans working independently and often in silos, Prospect Medical Holdings brings them under one convenient umbrella working in tandem. Our physicians, medical groups, and hospitals collaborate closely and in partnership with health plans to give patients streamlined, personalized care.

Prospect Medical Holdings also formalized a partnership with Waterbury HEALTH, a network of care located in New Haven County, CT. Waterbury Hospital, a 357-bed acute care hospital with strong academic teaching affiliations in an urban area, forms the cornerstone of Waterbury HEALTH.
Unfortunately, the facility was plagued by financial troubles and needed a partner to infuse capital to stay afloat. Prospect Medical Holdings stepped in by acquiring Waterbury Hospital in 2016, which now serves a population of about 119,000 people.
Today, our company continues to focus on the development of core operations and markets, as well as on further growth into new services and areas of the country. Our goal is to best serve the healthcare needs of both the communities in which we currently operate and the communities in other regions where we seek to grow.
Clinical Recognition and Accreditation
Our family of hospitals has won many awards over the years for excellence in patient safety and clinical quality. We have also received The Joint Commission accreditation and certification for our programs and services, as well as 4- and 5-star ratings for quality of care from the Centers for Medicaid and Medicare Services (CMS).
All of our hospitals are accredited by The Joint Commission, Det Norske Veritas (DNV), or the Healthcare Facilities Accreditation Program (HFAP).
