Peter Bastone, president and chief executive of Mission Hospital, has announced his resignation after more than a decade with the St. Joseph Health System.
He will leave Mission Hospital, which has locations in Laguna Beach and Mission Viejo, on June 30 for other opportunities.
"It is with mixed emotions that I announce my plan to resign," Bastone said in a statement. "With many of my personal and professional goals for Mission Hospital accomplished, I am excited about moving on to explore new challenges.
"At the same time, I leave behind an incredible staff, a hospital and health system that I have been proud and privileged to serve and a tremendously supportive community to which I remain deeply committed."
Bastone, 53, worked at the Daniel Freeman Memorial Hospital in Los Angeles before joining Mission Hospital in 1996.
Executive Vice President and Chief Operating Officer Joe Randolph credited Bastone's leadership for the accolades Mission Hospital has received in the last 15 years and for giving the hospital a national recognized reputation for quality healthcare.
