History
In the 1960s, the church's General Conference transferred ownership of the hospitals in the United States to the local conferences. In 1972, the General Conference centralized the management of its healthcare facilities, creating Adventist Health Systems.[6] The conferences then transferred the hospitals to the system, creating the entities Northwest Medical Foundation, and Adventist Health Services at the union level.[6]
In 1980, they merged creating Adventist Health System/West, which changed its name to Adventist Health in 1995.[6] The headquarters for Adventist Health was in Los Angeles,[6] Adventist Health worried about the smaller hospitals being neglected, so the headquarters was moved to Roseville, California in 1982. In 2019, a new Roseville shared service center replaced the corporate office that opened in 1985.[6]
In 2019, its headquarters was among six organizations awarded the Malcolm Baldrige National Quality Award for Performance Excellence.[7]
