The CEO of Centerpoint Medical Center for the past six years has announced his plans to retire.

David Williams, who has spent more than 30 years in health-care administration and became Centerpoint’s CEO in 2012, will retire effective May 1, according to Centerpoint’s parent company HCA Midwest Health.

During Williams’ tenure, Centerpoint constructed the $20 million Sarah Cannon Cancer Institute, a comprehensive, fully integrated oncology location. It also started an ongoing $60 million expansion to handle rapid growth in patient numbers.

“It has truly been a remarkable experience to be a part of this HCA family, and to be involved in Centerpoint’s transformation,” Williams said in a release. “I’m very proud of the work the Centerpoint team has done, and continues to do, to ensure that people in our region have access to choose top-notch compassionate healthcare close to home.”

Williams’ career began in 1984, when he served as an assistant administrator for Broward General Medical Center in Fort Lauderdale, Florida. He started working with HCA in 1987, as chief operating officer for Grand Strand Regional Medical Center in Myrtle Beach, South Carolina. After that, he served as CEO at Montgomery Regional Hospital in Blacksburg, Virginia (1996), Regional Medical Center Bayonet Point in Hudson, Florida (2001), Henrico Doctors Hospital in Richmond, Virginia (2005) and Rapides Regional Medical Center in Alexandria, Louisiana (2008) before taking the helm at Centerpoint, which had opened just a few years prior when HCA closed to older hospitals in Independence.

Centerpoint’s current expansion project includes:

• Three new floors, two fully developed and one for future growth.

• Expanding the number of medical/surgical beds by 36 and the number of ICU beds by 12.

• A new 16-bed physical medical inpatient rehabilitation unit.

• A redesigned emergency room, and a new service called Rapid ER Care, which is designed to improve wait times for ER patients with non-life threatening illnesses.

In the community, Williams has served on numerous boards, including the Independence Chamber of Commerce, the Truman Library Institute, the Independence Economic Development Council, the Rotary Club of Independence and the Truman Heartland Community Foundation.

M.L. Lagarde III, president of HCA Midwest Health, called Williams’ career “remarkable.”

“What I’ve found most impressive is his innate ability to form meaningful and last partnerships with employees and physicians, resulting in a high-quality health care experiences for patients,” he said in a release. “While it is difficult to say farewell, I know he is looking forward to spending more time with his family – Beth, his wife of 34 years, his children Michael and Claire and their families and his parents.”

HCA said it will begin searching for Williams’ replacement immediately.
