Chairman's Welcome

Welcome to the Department of Surgery at Stony Brook Medicine

Tass 2021

As a pivotal component of the largest University Medical Center in Suffolk County, The Department of Surgery is comprised of ten divisions consisting of over 60 specialized full-time faculty members, some of whom are national leaders in their fields.  We take great pride in not only the care we give to our patients but in the tutelage and training that our residents and faculty experience during their time at Stony Brook Medicine.  

Over the years, our department has remained committed to advancing our residents’ clinical and academic skills and trainees by pioneering ground-breaking surgical interventions, advanced simulation training, and innovative research. Our mission is simple, to provide advanced surgical experiences through highly skilled surgical teams with one end goal; to deliver the highest quality, patient-centered care to our communities.  

Our surgical practice known as Stony Brook Surgical Associates offers inpatient and outpatient care in a wide breadth of surgical specialties. With a large number of outpatient clinic locations, residents of Long Island don’t have to travel far to get access to exceptional care and cutting-edge treatment options.  

Our offices are strategically located throughout Suffolk County from Commack to The Hamptons and The North Fork.  Our commitment to multidisciplinary care allows our surgeons to work cohesively with their colleagues at University Hospital, Stony Brook Cancer Center, and Stony Brook Children’s Hospital.  Our affiliation with Eastern Long Island Hospital and Stony Brook Southampton Hospital allows us to offer the same patient-centered state-of-the-art surgical care to the population on the East End.  

In my fifteen years at Stony Brook Medicine, I have persistently focused on aspects of patient care that create long-lasting relationships and optimal surgical outcomes.  I strive to ensure that our patients and their families experience superior innovative and personalized care, entrusting us with their future care for many years to come.  I aspire to build upon our team’s past successes and establish the Department of Surgery at Stony Brook Medicine as the forerunner in advanced surgical practices and patient care.  I am confident that Stony Brook’s Department of Surgery will be unparalleled with the continued support of my colleagues, fellow administrators, and community.
