Stephen W. Mahan took the reins as CEO for Southern Regional Medical Center last week. He succeeds Clint Matthews, who has served as Southern Regional's CEO as part of an 18-month management contract between the hospital and FTI Healthcare. That contract will soon expire, and the Southern Regional Board launched a search for Matthews' successor several months ago. Mahan most recently served as the CEO at Muskogee (OK) Regional Medical Center.
