Brian Baumgardner will be retiring from his position as chief executive officer of LewisGale Regional Health System.

He will step down effective June 1, according to LewisGale spokeswoman Linda Scarborough.

HCA in 2016 named Baumgardner to take as CEO of LewisGale Regional Health System, overseeing its medical center in Salem and the community hospitals in nearby Montgomery, Alleghany and Pulaski counties.

The health system also includes two regional cancer centers, six outpatient centers and a stand-alone emergency room near Tanglewood Mall that opened during Baumgardner’s tenure.

Thomas Pentz, who has been CEO for decades at several HCA facilities in Tennessee and Florida, will serve as the interim CEO as the search begins to fill the position, Scarborough said.

During Baumgardner’s tenure, LewisGale started a graduate medical education program as part of HCA’s plan to address physician shortages by training residents who might stay and establish practices in their communities.

Until his move to Virginia, most of Baumgardner’s career had been in Florida.

He joined HCA in 1993.

He was named to the top LewisGale post after Jon Bartlett left the position earlier in 2016 to return to his home in Colorado.

Bartlett was at LewisGale for less than three years.
