Christopher M. O’Connor, FACHE

Chief Executive Officer, Yale New Haven Health

Christopher M. O’Connor is chief executive officer of Yale New Haven Health System (YNHHS), the largest and most comprehensive healthcare system in Connecticut and one that is recognized nationally for advanced clinical care. With more than 7,500 medical staff, 30,200 employees, and 2,600 hospital beds – and in partnership with the Yale School of Medicine – the academic health system provides comprehensive, integrated and family-focused care in 100+ medical specialties.

Mr. O’Connor joined the health system in 2012 as executive vice president and chief operating officer and was appointed president in 2020 and chief executive officer in 2022. Previously, Mr. O’Connor was president and CEO of the Saint Raphael Healthcare System and the Hospital of Saint Raphael, serving in that position until Saint Raphael’s successful integration into Yale New Haven Hospital in September 2012.

Since joining YNHHS, Mr. O’Connor has led a number of critical initiatives to advance strategic growth for the system, including the successful affiliation of L+M Hospital and Westerly Hospital into YNHHS and Milford Hospital into Bridgeport Hospital and the expansion of the physician network through the integration of PriMed – the largest physician group to join the system. To improve service to patients and staff and increase efficiency, he led the effort to systematize various functions across YNHHS, from pharmacy to employee health, and oversaw the opening of the regional operations center (ROC) for supplies and services.

Mr. O’Connor received his master’s degree in Health Services Administration from George Washington University in 1996 and his Bachelor of Arts, Economics from George Washington University in 1993.
