Lori Herndon, who began her career at AtlantiCare more than three decades ago as a nurse, will succeed David Tilton as president and CEO of the New Jersey subsidiary of Geisinger Health System.
Tilton, 64, will step down as chief executive on June 30 after nine years in the position and 29 years with the system.
Herndon, 55, will also serve as an executive vice president of Danville, Pa.-based Geisinger, which acquired AtlantiCare in 2015. The deal expanded Geisinger's geographic reach beyond its home state, where the system has also acquired hospitals.
