Melissa Magnuson


Dr. Melissa Magnuson grew up on a small pig and cattle farm in southern Minnesota, so it was no surprise that she’d acquire a love for animals. She earned a degree in biology and philosophy from Hamline University in St. Paul, MN, before earning her master’s degree from Southern Mississippi University. In 1998 she completed her Doctorate in Veterinary Medicine from the University of Minnesota in 1998, fulfilling her passion to help animals in need.

Shortly after graduating, she moved to the east coast for an internship in small animal medicine, surgery, and emergency medicine. She now has a special interest in surgery, emergency medicine, and avian and exotic animal care. Confucius said if you choose a job you love, you’ll never have to work a day in your life. Dr. Magnuson did just that; she chose a career she loves and is passionate about, so she never feels like she’s at work.

Dr. Magnuson is married to her best friend, Andy, with whom she has three beautiful daughters. She’s also a “pet mom” to four dogs, three cats, a bird, a bearded dragon, and a guinea pig. When she’s not at work, she enjoys spending time with her family outdoors, swimming, hiking, biking, and reading.

Rebecca Stephens


Originally from Massachusetts, Dr. Stephens has always considered herself a New Englander. She earned her Bachelor of Science degree in biology in 2009 from the University of Massachusetts-Dartmouth. She was also an avid member and captain of the university’s field hockey team at that time. In 2013, she earned her Doctorate of Veterinary Medicine from the University of Missouri in Columbia, MO.

It was during her years in college that Dr. Stephens discovered a passion for veterinary medicine. She has always loved science and animals, so veterinary medicine seemed like the perfect way to combine both of these interests. She now has a special interest in small animal surgery and clinical pathology. While she enjoyed her time out in the Midwest, she always knew she would end up back in the New England area.

Dr. Stephens currently resides in Massachusetts with her fiancé, Rafael, and their dog, Taj. Her personal interests include running with her dog, painting, reading, field hockey, and watching all of the Boston sports teams.

Dr. DeVito earned her Doctorate in Veterinary Medicine at the Cummings School of Veterinary Medicine at Tufts University. Prior to that, she obtained her bachelor’s degrees in both biology and flute performance at Indiana University. She has always been passionate about veterinary medicine, having been born into a family of animal lovers. Dr. DeVito has special interests in veterinary dentistry and emergency medicine.

A New Hampshire native, Dr. DeVito currently lives in Derry, NH. She is soon to be married to her high school sweetheart, Brian, with whom she shares a home with their three dogs and one cat. Her personal interests include woodworking, painting, and playing the flute.

She went on to complete an internship at Angell Memorial Animal Hospital in Boston in 1996, followed by a small animal surgical residency at Cornell University in 1999. After her residency, she returned to Angell as a staff surgeon for almost 12 years. She was also the director of the Surgery Residency Program there, where she trained more than 30 new board-certified surgeons.

Two years later, she became one of the first surgeons in New England to perform Tibial Tuberosity Advancements (TTAs) for cranial cruciate ligament repair. She takes prides in her ability to provide compassionate care for her patients, and she maintain open communication with their owners.
