Shortly after Dr. Thomas Malone took over as leader of Summa Health System this year, he moved his office out of Akron City Hospital.The health system’s executive wing had always occupied space within Summa’s flagship hospital.Now Summa’s top leaders work out of the health system’s Corporate Services Center, located in the former Roadway headquarters on Gorge Boulevard.The new president and chief executive is sending a clear message: Summa’s focus isn’t just hospitals anymore.“We’re much more than a hospital company now,” Malone said in a recent interview with the Akron Beacon Journal.
