Livonia, Mich.-based Trinity Health is combining its St. Joseph Mercy Health System and Mercy Health into one statewide system.

Rob Casalou, St. Joseph Mercy regional president and CEO, will lead the joined system as president and CEO starting Jan. 1, according to a news release.

The new system will consist of 10 hospitals and employ around 22,500, the release said. It will have 2,357 licensed beds, nine outpatient health centers, 12 urgent care centers and 35 specialty facilities.

The effort comes under Trinity Health’s nationwide “strategy to integrate teams and resources” and will help strengthen the brand, the release said. A name for the newly combined system has not yet been selected.

Mercy Health President and CEO Roger Spoelman will take on the national role of senior vice president of strategic and operational integration for Trinity Health, according to the release. He will work with Trinity Health executives to help lead the integration effort.

“Our new statewide system will enable our ministries to integrate our leadership in clinical and business operations throughout Michigan. For the communities we serve, this means it will enhance our clinicians’ ability to share resources and ideas that people need in their care journeys,” Mike Slubowski, president and COO of Trinity Health, said in the release. “Roger and Rob have been superb leaders in their regions, and we look forward to their roles in the new structure.”

Trinity Health operates in 22 states and employs about 131,000. It has annual operating revenues of $17.6 billion and assets of about $24.7 billion, it said in the release.
