Vaughn Williams, who worked as chief operating officer at Cedar Hill Regional Medical Center, resigned effective May 30, the Washington Business Journal first reported.

Williams has served since fall 2023 as the inaugural chief operating officer at Cedar Hill — owned by Universal Health Services, which also owns the Foggy Bottom GW Hospital — through the medical center’s opening in April. Williams’ resignation — effective May 30, a hospital spokesperson told the Washington Business Journal — comes in the wake of staffing concerns about the new hospital from local government leaders due to the financial turmoil of the Medical Faculty Associates, a network of physicians who teach at the School of Medicine & Health Sciences and service medical centers, which UHS tapped to staff the hospital.

Neither UHS nor Williams immediately returned a request for comment.

The resignation comes as the hospital seeks to fill nearly 200 positions, including a chief medical officer and director of human resources, according to the hospital’s careers page.

Williams joined Cedar Hill from UHS’ Las Vegas market, where he’s served as an administrator since 2021, according to his Cedar Hill bio, which still lists him as COO as of Wednesday.

From 2021 to 2023, Williams launched clinical programs, grew outpatient services by over 100 percent and oversaw over $250 million in construction projects in the Las Vegas market, his bio states.

Prior to his post at UHS, Williams worked for Sutter Health in California, first as an administrator from 2017 to 2018 then as the Valley Area Director. He then worked as the project manager for University of Michigan Medicine from 2015 to 2017.
