Melissa Magnuson


Dr. Melissa Magnuson is a native of southern Minnesota, where she grew up on a small pig and cattle farm. Ever since she can remember, she’s wanted to be a veterinarian and fulfill her lifelong passion of helping animals. With a degree in biology and philosophy from Hamline University in St. Paul, MN, she went on to work on a master’s degree at Southern Mississippi University. From there, she completed her Doctorate in Veterinary Medicine at the University of Minnesota in 1998.

Her internship in small animal medicine, surgery, and emergency medicine brought her to the east coast. She has a special interest in surgery, emergency medicine, and avian and exotic animal care. Because she absolutely LOVES veterinary medicine, she never feels like she’s at work. She feels very lucky to have found her passion.

Dr. Magnuson is married to her best friend, Andy, with whom she has three beautiful daughters. Her pets include four dogs, three cats, a bird, a bearded dragon, and a guinea pig. In her spare time, she enjoys being with her family outdoors, biking, hiking, swimming, and reading.

Patti Dressel


Dr. Patti Dressel is a New England native. She grew up in Massachusetts and completed her Bachelor of Science degree in pre-vet/animal sciences from the University of Vermont. She then moved to Colorado to continue her education and fulfill her lifelong dream of becoming a veterinarian. She earned a Master of Science degree in anatomy and a Doctor of Veterinary Medicine degree from Colorado State University.

After graduating from veterinary school, she worked in a large 24-hour general practice/emergency clinic in Baltimore, MD, for two and half years. She then worked in southern New Hampshire at another large practice for several years. Her passions include the diagnosis and treatment of complicated cases, surgery, and emergency medicine. Developing and maintaining a client bond is also very important to her.

Dr. Dressel is happy to be back in New England, closer to family and friends. Her family is very important to her and includes her husband, Rob; daughter, Ryleigh; and son, Evan. She also has three rescued animals: two mixed breed dogs named Kezar and Kyna and a cat named Keagan. In her spare time, you may find her at a Patriots or Red Sox game, as she was born and raised a New England sports fan, and this has never changed. She also enjoys spending time outdoors, especially with her family.
