Rockville Centre -– Catholic Health Services (CHS) has named Alan D. Guerci, MD, president and chief executive officer (CEO), effective July 1. He is currently executive vice president for CHS and president and CEO of CHS’s St. Francis Hospital, Mercy Medical Center and St. Joseph Hospital. Dr. Guerci succeeds Richard J.J. Sullivan, Jr., who has been serving as the system’s CEO on a voluntary basis since December 2012, in addition to his ongoing duties as chairman of CHS’s Board of Directors.

“Dr. Guerci brings more than 20 years of service to CHS and has established himself in the Long Island community as a highly respected physician and accomplished health care leader,” said Sullivan. “He is well versed in hospital administration and is focused on Christ’s healing mission and achieving the highest levels of quality with a commitment to excellence and financial stewardship.”

Prior to assuming executive leadership for St. Francis Hospital, The Heart Center, in 1999 (and Mercy and St. Joseph more recently), Dr. Guerci -— a nationally renowned cardiologist -— was St. Francis’s executive vice president for medical affairs and director of research. Previously, he served as director of the Coronary Care Unit at The Johns Hopkins Hospital, as well as chairman of the Clinical Trials Review Committee of the Heart, Lung and Blood Institute of the National Institutes of Health.

At St. Francis, Dr. Guerci oversaw the largest expansion project in the hospital’s history, the first phase of which was completed in 2008 with the opening of the 158,000-square-foot Nancy and Frederick DeMatteis Pavilion. In October of 2012, St. Francis’s newly renovated Emergency Department was unveiled—the region’s first “green” ED, featuring electrically operated privacy glass, high-efficiency light fixtures and other innovations to minimize the facility’s “footprint”.

After graduating from Harvard College, Dr. Guerci earned his medical degree from Cornell University Medical College and a master’s degree in health care management from the Harvard School of Public Health. He completed postgraduate training as an intern, resident and chief resident at the University of California, San Francisco Medical Center, followed by a fellowship in cardiology at The Johns Hopkins Hospital, where he advanced to the rank of associate professor of medicine before joining St. Francis. In addition, he is an associate professor of clinical medicine at the College of Physicians and Surgeons of Columbia University.

Dr. Guerci resides in Sea Cliff with his wife, Leslie.
