Adventist Health and St. Joseph Health Announce Formation of a New Joint Operating Company


Adventist Health and St. Joseph Health announced an agreement on Monday, April 23, to integrate clinical activities and services through a new joint operating company. The partnership will extend across clinics and facilities in Humboldt, Mendocino, Sonoma, Lake, Napa and Solano counties. The proposed arrangement is subject to regulatory review.

“Adventist Health and St. Joseph Health believe this is the right thing to do for the communities we serve,” said Jeff Eller, Adventist Health president of the Northern California region. “Patients will benefit from more access points, better health outcomes and controlled costs by coordinating their care across the spectrum of their health needs.” 

The affiliation applies to facilities, services and clinics associated with Adventist Health Howard Memorial, Adventist Health Ukiah Valley, Adventist Health Clear Lake, Adventist Health St. Helena and Adventist Health Vallejo and Home Health services and facilities, services and clinics associated with St. Joseph Hospital Eureka, Redwood Memorial Hospital, Santa Rosa Memorial Hospital, Queen of the Valley Hospital and the St. Joseph Home Care Network. The arrangement does not include the other 15 Adventist Health hospitals in the western United States or the other 50 Providence St. Joseph Health hospitals located throughout the western United States and Texas. Under this affiliation, Adventist Health and St. Joseph Health will retain existing hospital names, licenses, capital assets and employees.  

“Both Adventist Health and St. Joseph Health have a strong history of successful clinical collaboration. This is an extraordinary moment in the histories of St. Joseph Health and Adventist Health,” said Kevin Klockenga, St. Joseph Health Northern California Region president and chief executive officer. “By coming together under a new organization, we will work together to ensure a healthier future for the communities we serve by providing patients access to a full continuum of high-quality services close to home.”

Officials at Adventist Health and St. Joseph Health are working toward a closing of the proposed transaction sometime later this year. Meanwhile, both organizations remain committed to delivering exceptional care throughout the region.
