LINCOLN, Maine — A Florida administrator with 30 years of experience will oversee Penobscot Valley Hospital as the institution’s leaders search nationwide to replace departed CEO David Shannon, officials said Tuesday.

Lynn W. Beasley served as chief executive officer for Hendry Regional Medical Center in Clewiston, Fla. He also served hospitals in South Carolina and Louisiana, said Kristie Libby, the hospital’s marketing and fund development manager. He has been in health care for nearly 30 years.

“He’s already been officially welcomed to Maine with two snowstorms and been stuck in the snow at the end of his driveway,” Libby said Tuesday. “But on a serious note, Lynn is pleased to be working with an engaged board of directors here at PVH, and has enjoyed seeing how dedicated our providers and staff members are to patient care.”

The hospital’s management organization, Quorum Health Resources, has launched a nationwide search for Shannon’s successor. A company out of Brentwood, Tenn., QHR hires and oversees the work of the hospital’s CEO and CFO, Libby said.

“That is expected to take three to six months,” Libby said Tuesday.

Beasley started work at Penobscot Valley on Tuesday, March 25, Libby said.

The hospital’s board of directors accepted Shannon’s resignation in February, effectively agreeing to end Shannon’s more than 20-year career with the hospital as its chief financial officer, executive director and CEO.

Shannon said in a statement released by Libby that he will work as CEO of Jersey Shore Hospital of Jersey Shore, Pa. The new job will allow him to be closer to family in an area a few hours from where he grew up.

The hospital is hosting a meet-and-greet for Beasley from 2 to 3:30 p.m. Thursday, April 10, in conference room A on the second floor at PVH. The public is invited, Libby said.
