I started the PA program at Northeastern University in October of 1988. Since first picking up a stethoscope, I have loved being a PA. Many of my patients have shown courage and dignity at a most vulnerable time in their lives, often with good cheer. 

Great joys in my life include grand babies, my chubby cat, dog walks and kayaking at sunset. My passion project is making stained glass panels which feature birds, fish and animals in their natural habitat.

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.

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.
