Greg Hurst, president of finance and development, will continue to oversee the CEO responsibilities.

During his tenure, Stack oversaw a number of acquisitions, such as Newnan (Ga.) Hospital in 2007 and Mountainside Medical Center, Jasper, Ga., in 2004. Before joining Piedmont, Stack was president and CEO of Borgess Health Alliance and Borgess Medical Center, Kalamazoo, Mich. He was also president and CEO of South Side Healthcare System, and senior VP and COO of Central Medical Center and Hospital, both in Pittsburgh. Stack also left the system in 2003 for a brief stint at the helm of MedQuist, a healthcare technology firm in Marlton, N.J. Piedmont did not disclose the cause of death.
