WARREN - Chief Executive Officer Bob Wolleben and Chief Nursing Officer Cynthia Lewis resigned their posts at Trumbull Memorial Hospital, effective Friday, the same day the hospital announced the changes.
A prepared statement released after business hours Friday by the hospital did not indicate a reason.
A search for a new CEO and CNO is under way. Members of the board of trustees, medical staff and administration will be involved in the process.
"Both Bob and Cynthia's accomplishments have continued Trumbull's commitment to patient care and safety," said Kirk Ray, CEO of ValleyCare Health System of Ohio. "The strides made during their time here have positioned the hospital for success."
Wolleben joined the hospital in 2009 as Chief Operating Officer and was promoted to CEO in 2010. During his tenure, the orthopedic floor was renovated with all-private patient suites, walk-in showers and new patient care equipment. The hospital also added new technology including four CT scanners, lab blood chemistry equipment, a surgical lighting system and upgraded IT systems.
Lewis, who joined Trumbull in 2011, led the implementation of clinical hourly rounding at the hospital.
