Dr. Mark E. Peterson was awarded a Doctor of Veterinary Medicine degree with High Distinction from the University of Minnesota in 1976, where he graduated as class Valedictorian. After moving to New York City, Dr. Peterson first completed an internship and medical residency at The Animal Medical Center, the largest animal hospital in the world. He then finished a post-doctoral fellowship in both endocrinology and nuclear medicine at The New York Hospital-Cornell Medical Center. This fellowship was awarded and funded by the National Institutes of Health. In 1981, he obtained board certification as an Internal Medicine specialist from the American College of Veterinary Internal Medicine.


Dr. Peterson served as head of endocrinology and nuclear medicine at The Animal Medical Center for over 30 years. In addition, Dr. Peterson has held positions as Adjunct Professor of Medicine at the School of Veterinary Medicine at the University of Pennsylvania (1996-2000), Associate Professor of Radiology at the Weill Medical College of Cornell University (1983-2005), and Assistant Professor of Medicine at the New York State College of Veterinary Medicine, Cornell University (1982-1988).

Over the last 45-plus years, Dr. Peterson has directed most of his research toward advancing our understanding of endocrine disorders in dogs and cats. He is especially interested in hyperthyroidism and diabetes mellitus in cats and hypothyroidism, diabetes mellitus, Cushing’s syndrome, and Addison’s disease in dogs. Dr. Peterson was the first veterinarian to document hyperthyroidism in cats (1979) and the first to treat hyperthyroid cats with radioiodine (1980). In addition to hyperthyroidism, Dr. Peterson was the first person to document a number of “new” diseases in cats, including acromegaly, hypoparathyroidism, insulinoma, and Addison’s disease.


He has received several awards in recognition of his clinical research and discoveries, including the Beecham Award for Research Excellence (1985), the Ralston Purina Small Animal Research Award (1987), the Carnation Award for outstanding contributions to feline medicine (1988), the Merit Award of the Veterinary Medical Association (VMA) of New York City (1989), the British Small Animal Veterinary Association (BSAVA) Bougelat Award for outstanding contributions to small animal practice (1993), The Daniels Award for excellence in the advancement of knowledge concerning small animal endocrinology (1991-1997, 1999, and 2001), The Excellence in Feline Research Award, presented by the American Veterinary Medical Foundation and sponsored by The Winn Feline Foundation (1997), the Alumni of the Year Award, The Animal Medical Center (1998), the Award for Outstanding Humanitarian Service from the Bide-A-Wee Association for more than a quarter century of dedicated research in endocrine disorders of dogs and cats (2002).

In 2005, Dr. Peterson relocated Hypurrcat to a larger space in Bedford Hills. In this new space, he also founded the Animal Endocrine Clinic and purchased the nuclear medicine equipment needed to open a nuclear imaging center (Nuclear Imaging for Animals). The Bedford Hills office was closed in early 2020 to allow Dr. Peterson to focus on his continued research.


In 2009, Dr. Peterson opened an office on the Upper West Side of Manhattan in New York City. He sees endocrine patients in his New York City clinic, which features the Hypurrcat facility for treating hyperthyroid cats with radioiodine.
