Dr. O’Brien has lived in Dorchester all her life, but having attended Notre Dame Academy in Hingham for high school, she has a little “South Shore connection” as well.  She graduated from Emmanuel College with a BS in Biology in 2002 and spent 

the next two years working as a veterinary technician at VCA South Shore Animal Hospital in Weymouth, before attending Tufts School of Veterinary Medicine where she earned her doctorate in 2008.  Dr. O’Brien went on to complete a rotating internship in Small Animal Medicine and Surgery at New England Animal Medical Center in West Bridgewater. She then practiced at a small animal clinic in Boston before spending the past several years as a relief veterinarian in the Boston and South Shore areas, traveling between practices. 

Dr. O’Brien has a Golden Retriever named Lily who loves people and a talkative African Grey Parrot named Robin. Lily’s love for hiking and new adventures and Robbie’s love of music and hide-and-seek keeps her busy.  Dr O’Brien also has an interest in digital design, photo restoration, and genealogical research. As a cancer survivor with a jawline disfigurement, she is fond of the saying, “Don’t judge a book by its’ cover.” This also comes into play in veterinary medicine with the many sweet loving pitbulls and the occasional “ferocious” tiny teacup dog!
