David Tilton announced Thursday that he will retire as president and CEO of AtlantiCare health system on June 30, after 29 years with the organization. Tilton has been the President of AtlantiCare, one of South Jersey's largest employers, since 2007.

With Tilton at the helm, AtlantiCare experienced robust growth of services across the region, expanding to six major campuses and nearly 90 sites, enhancing clinical programs and securing key affiliations.

Tilton also oversaw AtlantiCare's merger with Geisinger Health System in 2015.

The AtlantiCare board of trustees said Executive Vice President Lori Herndon will succeed Tilton. Herndon started as a nurse at AtlantiCare 30 years ago.

Herndon, a Stockton University alumna, served in executive roles for the system since 2007, overseeing strategic clinical and process integration with Geisinger Health System.

In a statement, Tilton endorsed Herndon as his replacement. “I think she’s an exceptional leader, and they’re lucky to have her. She’s focused on our people and performance improvement. I think, if anything, we’re really well positioned for the future,” he said.

AtlantiCare has more than 5,400 employees and more than 700 physicians.
