Dr. Francis Martorana (A.K.A. Dr. Frank) is a co-owner of the Hamilton Animal Hospital and the Cazenovia Animal Hospital. He did both his undergraduate work and veterinary training at Cornell University. He graduated in 1976 and joined the practice soon after. Until 1993, Dr. Frank was seen as often in horse barns or on dairy farms as in the office. However, since opening the Hamilton Animal Hospital he practices mostly on dogs and cats. Dr. Frank and his wife, Ann Marie, live in Nelson. When he’s not at the animal hospital you’ll usually find him either making more award winning wine in his home winery or fly fishing in the Adirondacks.
