It bought out Beaumont Health of Metro Detroit in 2022. The merger of the two hospital groups formed what is now known as Corewell Health. Spectrum Health's subsidiaries included hospitals, treatment facilities, urgent care facilities, as well as physician practices that served the western Michigan area. Priority Health was a subsidiary health plan with one million members. Spectrum Health was the largest employer in West Michigan at the time of the merger with 31,000 staff, 4,200 physicians and advanced practice providers, including 1,600 members of the Spectrum Health Medical Group, and 3,200 volunteers.
