Community Health Systems announced that David L. Miller, president and chief operating officer, will retire at the end of the year. Miller departs after 19 years with CHS.
Miller held various leadership positions since he joined the Franklin, Tenn.-based health system in 1997 including senior vice president of group operations and division president. He was CHS' first chief operating officer, a position he has held since January 2014.
As president and COO, Miller oversaw 198 of CHS' affiliated hospitals in 29 states, as well as outpatient services.
Throughout his career at CHS, Miller led the acquisitions of Triad Hospitals in 2007 and Health Management Associates, Inc. in 2014.
CHS is the nation's second-largest investor-owned hospital company. CHS announced that on April 29 it will spin off 38 hospitals into an independent company called Quorum Health.
The health system posted disappointing earnings in 2015. CHS reported a net loss of $83 million, or 73 cents per share, in its fourth quarter, compared with net income of $100 million, or 88 cents per share, in the prior-year quarter.
