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.
