Corewell Health is currently the largest healthcare system in Michigan, based on its inpatient admissions and net patient revenue.

[2] The hospitals, the overall health system and the Oakland University William Beaumont School of Medicine are all named for William Beaumont, a U.S. Army surgeon who became known as the "Father of Gastric Physiology" following his research on human digestion started at Fort Mackinac on Mackinac Island, Michigan.

[7] In 2020, Beaumont and Advocate Aurora Health, a 28-hospital system in Illinois and Wisconsin, announced plans to merge into a combined company worth $17 billion.

[8][9] These plans were called off in October 2020, in part because physicians, lawmakers, staff, and donors were concerned that it would harm patient care.

[2] The headquarters of Corewell Health is 100 Michigan St NE on the Grand Rapids Medical Mile.

In 2019, Spectrum announced it would centralize its staff, totaling 1,200, into a single building in Downtown Grand Rapids.

The Downtown Development Authority (DDA) of Grand Rapids approved Spectrum's plan in October 2021.

It was developed to bring all cancer research and patient service delivery under one roof in the Spectrum Health System.

[14] Following public pressure, including calls for a boycott of the system, Corewell reverted to its previous policy, providing abortion when deemed medically necessary.
