He lives in Milton, Vermont, with his wife Julie, their son Logan, three cats, a dog, and a flock of chickens. Outside of the clinic, he enjoys hiking, traveling, photography, collecting vinyl records, and spending time with his family.

Dr. Mike grew up in Connecticut and graduated from the University of Connecticut before attending veterinary school at Cornell University. Prior to his arrival at Petit Brook, he was a partner in a large mixed practice in Northern NY and then a small animal practice here in VT. From his perspective, sharing information with clients and having them involved in decisions about their pets are the cornerstones of veterinary medical practice. He is involved in coaching softball, basketball, and Odyssey of the Mind with his wife and children. He loves hiking and being on the lake. His dogs have included everything from dachshunds to Great Danes.

Dr. Alli is a 2023 graduate of the Ontario Veterinary College, where she completed both her undergraduate and veterinary studies. She divides her time between treating horses and working with dogs and cats at Petit Brook.

With a special interest in pain management through spinal manipulation, exercise, and medication, Dr. Alli focuses on supporting aging pets and athletes. Her love for veterinary medicine comes from the strong bonds she’s shared with pets throughout her life.

When not working, she enjoys hiking, Cross-Country Skiing, running, and exploring the natural beauty of Vermont, New Hampshire, and New York with her fiancé, two dogs, and two cats.
