U-M Health Statewide Network of Care

U-M Health Hospitals, Health Centers and Affiliates 

University of Michigan Health is committed to ensuring Michiganders have access to the right care in the right place. That means keeping care close to home as much as possible by collaborating with hospitals around the state to expand local access to specialty care. It means working with community-based health providers to serve patients near where they live and work, whenever possible. 

And, when a patient does have to travel to receive care from one of our specialists, we work to coordinate that care with local providers so patients have a seamlessly integrated experience and can return home for as much of their treatment as possible. 

We have developed a number of collaborations and affiliations with health systems, hospitals, and providers throughout the state to fulfill this mission, and we continue to explore opportunities to create new partnerships that best serve the people of Michigan.
