St. Joseph Health System said Monday that Peter Bastone, the longtime president and chief executive of its Mission Hospital, would resign on June 30 to pursue other opportunities.
Bastone, 53, has been with Mission, which has campuses in Mission Viejo and Laguna Beach and 541 beds, since 1996. He came to Mission from Daniel Freeman Hospital in Inglewood.
During his time at Mission, Bastone oversaw a $153 million expansion, including the construction of a 94,900-square-foot patient tower.
He was also over the conversion of what was previously South Coast Medical Center into Mission Hospital Laguna Beach after parent St. Joseph paid $36.5 million for it in 2009.
Orange-based St. Joseph will launch a search for Bastone’s replacement and has not yet tapped an interim chief executive, a spokesman said.
St. Joseph, a Catholic healthcare provider, also owns St. Joseph Hospital-Orange and Fullerton’s St. Jude Medical Center.
