Dr. Sefchuk joined the staff at NMSVC after graduating from Tuft's Veterinary School in 1989. As the primary surgeon, she spends most of her time in the surgery suite performing spays, neuters, lumpectomies, dentals and other soft tissue surgeries. Dr. Sefchuk breeds and shows English Bulldogs, and has a large clientele of Bulldog owners who travel far and wide to have their dogs treated by a veterinarian who knows the breed so well.

Dr. Sefchuk lives on the south shore, and shares her home with several Bulldogs. She is currently the President of the Bulldog Club of New England, and the past Vice President of the Bulldog Club of America. She enjoys gardening and is a big Boston sports fan.
