VCA Laconia Animal Hospital

John Guest, DVM, Associate Veterinarian

DVM, Virginia-Maryland Regional College of Veterinary Medicine


Dr. John Guest came to the Lakes Region having moved here from Virginia in 1999 after completing his veterinary training at the Virginia-Maryland Regional College of Veterinary Medicine. Prior to veterinary school, Dr. Guest worked at the Food and Drug Administration, using his electrical engineering degree to evaluate human medical devices.
During his years at VCA Laconia Animal Hospital, Dr. Guest has developed special interests in skin disease and heart disease. "Skin and ear problems are among the most common problems seen in dogs and cats, and can cause significant discomfort to the pet," comments Dr. Guest. "Finding the right treatment to help a pet can be challenging, but is very gratifying to help a pet feel so much better." Cats and dogs with heart disease often are initially evaluated by specialists, and then have continued care with general practitioners. "New medications and even nutritional supplements can really help pets with heart disease live longer and feel better," comments Dr. Guest.
Dr. Guest lives with his wife Kathryn (also a veterinarian at our hospital), children Connor, Ella, Madelyn & Caroline plus 3 cats and 2 dogs in Gilford. When he is not working, Dr. Guest enjoys hiking and mountain-biking the trails of the Lakes Region and White Mountains.
