I am a Cum Laude graduate of Tufts University, and I earned my medical degree at the Tufts University School of Medicine. I completed my surgical residency at New York Medical College, and my urological residency at Westchester Medical Center in Valhalla, NY. I came to South Shore Urology on completion of his residency. I am certified with the American Board of Urology and I am passionate about providing high quality patient care in a compassionate environment.

Having sustained a major trauma or having undergone any kind of surgery (major or minor) can be extremely stressful. I often find myself treating patients and talking with families when they are often feeling at their worst. This is the time when I feel my warm personality and compassion can be the biggest contributors to alleviating some of that stress and anxiety. Outside of my practice, I prefer to spend time with my family enjoying the splendors of the South Shore.

My mission as an emergency department physician is to provide timely and excellent care to patients while helping them through what are likely very stressful and difficult emergency situations.

I grew up in southern New Hampshire and attended Providence College in Rhode Island. I then obtained my MD at the University of Connecticut. I completed my emergency medicine residency at the University of Cincinnati and while I loved the Midwest, I always planned to come back to New England and was happy to move to the South Shore. In my free time I enjoy hiking, skiing, and spending time with family and friends.

I received my undergraduate degree from Harvard University. I completed my medical degree at the Robert Wood Johnson Medical School in Camden, NJ. My surgical and urological residency took place at the State University of New York Health Science Center in Brooklyn, NY. I am certified with the American Board of Urology and am passionate about providing high quality patient care in a compassionate environment.

Having grown up on the South Shore, it is a pleasure to care for patients of this region. I served in the US Navy following medical school and completed my surgical training through the Navy. Following multiple military assignments, I chose to return to the area in order to serve my local community and reside closer to my family.
