ANN ARBOR, Mich. – On Monday, the Saint Joseph Mercy Health System named Alonzo Lewis as the new president of St. Joseph Mercy Ann Arbor and St. Joseph Mercy Livingston hospitals.

"Alonzo is a trusted leader who has taken on significant initiatives for St. Joe's with remarkable results," said Rob Casalou, president and CEO of Trinity Health Michigan and Southeast Regions in a statement. Saint Joseph Mercy is a division of Trinity Health.

“Since joining our organization four years ago, he has led St. Joe’s with a thoughtful, analytical approach to tackling tough issues, building strong teams and designing effective service line strategies while passionately supporting our healing mission. As we continue to reinstate programs and services following the COVID-19 pandemic, I feel fortunate to have such an experienced and capable leader at the helm.”
