Jim Terwilliger, president of Indiana University Health’s Methodist and University hospitals, will step down March 1. He had led IU Health’s two flagship hospitals since July 2012, when longtime executive Sam Odle retired. Dennis Murphy, whom IU Health hired to fill Odle's other job of chief operating officer, decided to replace Terwilliger. Dr. Jeff Sperring, CEO of IU Health’s Riley Hospital for Children, will serve as interim president of Methodist and University hospitals, while IU Health conducts a search for a permanent replacement.
