North Tampa Behavioral Health

Clint Hauger was appointed CEO of North Tampa Behavioral Health after regulators found its former CEO—an ex-NFL player—was unqualified for the job, the Tampa Bay Times reported.

The behavioral health center was the focus of a Times investigation last year that found, among other things, the hospital’s then-CEO Bryon Coleman had no experience in healthcare.

> Donald Webb, CEO of Franklin, Tennessee-based Williamson Medical Center, plans to retire at the end of the year after 35 years of service, the Tennessean reported. Webb joined the medical center in 1985 as controller and was chief financial officer for 16 years before becoming CEO in 2012.
