Melissa Mazan - DVM, DACVIM

Melissa Mazan
Internal Medicine, Equine Respiratory System, Lung Function

Dr. Melissa Mazan is a Professor at the Cummings School of Veterinary Medicine's Hospital for Large Animals. Lung function, she notes, is essential to the success of equine athletes, and optimizing performance for competing horses is a particular thrill for her. Dr. Mazan is proudest of the collaboration she has undertaken with Dr.Andrew Hoffman in the area of equine inflammatory airway disease, which affects as many as 80 percent of stabled horses and has provided pathways to better understanding similar human diseases, such as emphysema.

Dr. Mazan also teaches courses on medicine, toxicology, parasitology, and exercise physiology at the Cummings School, where she was drawn by the opportunity to combine research, clinical work, and teaching.

Dr. Mazan enjoys hiking, playing the piano, and spending time with family and friends. She is married to Edward Deveney, a physicist who teaches at Bridgewater State College. They have two daughters, Chloe and Rae. They also share their house with two cats and a dog. Dr. Mazan and her family reside in North Grafton, Massachusetts.
