Alameda Health System (AHS) is an integrated public health care system of five hospitals and four wellness centers with over 800 beds and 1,000 physicians. Founded in 1864 as Alameda County Infirmary, we’ve forged a legacy of commitment to our communities.
By the 1920s, our Fairmont Hospital emerged as the first public rehabilitation facility in the West. In 1927, Highland Hospital opened, pioneering its own school of nursing. The ‘60s brought an innovative network of neighborhood-based clinics, essential for wellness and preventive care.
John George Psychiatric Hospital opened in 1992, as our separate components consolidated into what is now Alameda Health System, employing over 4,500 and charged with ensuring quality health care for all. Most recently, AHS added San Leandro and Alameda hospitals.
The heart of the AHS mission – Caring, Healing, Teaching, Serving All – continues to drive innovation, change and growth as we promote wellness and eliminate health care disparities.
