Mark Crandall was the second veterinarian in his family. Unlike his brother, James, who entered Cornell out of high school and received his DVM in 1931, Mark spent three years at Syracuse University before entering Cornell in 1935 during the depths of the Depression. After graduation in 1939, he worked in Dryden, New York, where he established the first artificial insemination program for cattle in the area. He and his wife, Cora, moved to Gloversville in Fulton County the following year, where he established a general practice and raised his two daughters. He built the Glove Cities Veterinary Hospital in 1964 to meet the growing needs for small animal pet care in the community. He retired in 1977. Throughout his entire career, Dr. Crandall has been very active in the local community. At the age of 96, he still leads a singing group that provides weekly entertainment for patients in the extended care of the local hospital.
