Twin Cities Community Hospital Chief Executive Officer Rick Lyons is leaving his post in July, prompting the Templeton facility to launch a search for his successor.
Lyons, 64, plans to retire July 6 and remain in Templeton with his family.
Hes held the post at the North County hospital held under Texas-based parent company Tenet Healthcare Corp. since 2003.
Rick Lyons has been a driving force behind the mounting successes and notable developments that Twin Cities has seen in recent years, Jeff Koury, senior vice president of operations for Tenets California region, said in a statement.
Among those developments is the hospitals expansion from 84 to 122 beds from 2007 to 2010 and the construction of a new hospital tower for renovated intensive care, emergency and obstetrics units in 2007.
The Medical Arts Center, a primary care division on campus, was the hospitals newest addition and opened in December.
In Lyons nine years at Twin Cities, the hospital also added more than 70 physicians to its medical staff and received Tenet Healthcares Circle of Excellence award four times.
Among Lyons volunteer endeavors are CenCal Health, San Luis Obispo Countys Medi-Cal managed care insurance plan; the Paso Robles Chamber of Commerce; and the San Luis Obispo YMCA.
Officials say they hope to find a successor as soon as possible. Officials at the corporate office declined to give the time frame of the search or provide a pay range for a chief executive officer. Existing hospital administrators will divvy up the leadership responsibilities in the interim.
The permanent replacement will be responsible for overseeing the 142,400-square-foot hospitals approximately $50 million annual budget and 496 employees.
