LifePoint Hospitals announced today that veteran hospital CEO Mary Jo Lewis is retiring.

Lewis has served since 2010 as CEO HighPoint Health System, which was formerly known as Sumner Regional Health Systems. She was brought in after LifePoint purchased the system. Prior to that, she served as CEO of another LifePoint facility in Kentucky.

“I want to thank Mary Jo for her many valuable contributions to HighPoint Health System. She was instrumental in leading the successful transition of HighPoint following LifePoint’s acquisition of the hospital system almost two years ago,” said division president Jeff Seraphine. “I am also appreciative that she has made herself available to help during this transition as we search for the next CEO of HighPoint. While we will miss Mary Jo, we wish her the very best in her retirement.”

According to the company, Seraphine will work with Lewis to ease the leadership transition. A search is currently underway for Lewis’ replacement.
