The story

Origins

The system originally traced its roots to three independent hospital networks: William Beaumont Hospital, Botsford Hospital, and Oakwood Hospital.

Groundbreaking began in 1953 for "Oakland Hospital," but due to a delivery mix-up and to further distinguish itself from nearby Oakwood Hospital, the name was changed to William Beaumont Hospital. The hospital officially opened on January 24, 1955, with 238 beds in Royal Oak, Michigan. The hospital was named for William Beaumont, a U.S. Army surgeon who became known as the "Father of Gastric Physiology" for his research on human digestion on Mackinac Island, Michigan.

Botsford General Hospital opened in 1965 with 200 beds in Farmington Hills, Michigan. It was founded by Dr. Allen Zieger as an expansion of the Zieger Clinic Hospital he had opened in Detroit in 1944.

Oakwood Hospital opened on January 5, 1953, in Dearborn, Michigan, on land donated by Henry Ford II and the Ford Motor Company. The decision to build a "voluntary" hospital was initially controversial, as Dearborn mayor Orville L. Hubbard had supported a competing proposal for a municipal facility.

2014 merger

In March 2014, the Beaumont Health System, along with Botsford Health Care and Oakwood Healthcare, signed a letter of intent to merge their operations. The $3.8 billion merger closed on September 2, 2014, and the combined organization adopted the shortened name Beaumont Health.

Failed merger attempt with Advocate Aurora

In 2020, Beaumont and Advocate Aurora, a 28-hospital system in Illinois and Wisconsin, announced plans to merge into a combined company worth $17 billion. These plans were mutually called off in October 2020 following intense pushback from physicians, lawmakers, staff, and donors who expressed deep concerns over patient care, as well as a "toxic culture" of fear and intimidation under then-CEO John Fox. Following the collapse of the merger, leading Beaumont physicians sent formal letters to the board calling for the termination of Fox and other executives, citing massive layoffs alongside controversial multi-million dollar executive bonuses.

Merger with Spectrum Health

In June 2021, Beaumont Health announced a new plan to merge with Grand Rapids-based Spectrum Health. Following federal regulatory approval, the merger became effective on February 1, 2022. The new statewide system was temporarily called BHSH Health, operating with dual headquarters in Grand Rapids and Southfield. John Fox resigned upon the completion of the merger, and Spectrum CEO Tina Freese Decker took over leadership of the combined system. In October 2022, the system was permanently rebranded as Corewell Health.

Pediatric care

Beaumont Children's Hospital was announced in 2009 at the Royal Oak campus, eventually joining the Children's Hospital Association and becoming the only Southeast Michigan affiliate of the Children's Miracle Network Hospitals. The network maintained dedicated pediatric inpatient units at the Royal Oak, Troy, Dearborn, and Farmington Hills campuses. Following the 2022 merger, the pediatric division was integrated into Corewell Health Children's.

Headquarters

In 2017, Beaumont Health purchased the 31-acre First Center Office Plaza in Southfield to consolidate and centralize its administrative offices. Following the merger with Spectrum Health, this location was maintained as the Metro Detroit administrative office for Corewell Health.
