Dr. Mark E. Peterson's Bio

Mark E. Peterson, DVM,

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 Oxford Award for Excellence in the Advancement of Knowledge Concerning Small Animal Endocrinology (2019, 2020, 2022), 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). Dr. Peterson received the Outstanding Service to Veterinary Medicine Award from the VMA of New York City (2008), the Presidential Service Citation from the VMA of New York City (2011), and the Presidential Citation from the New York State Veterinary Medical Society (2011). Most recently, Dr. Peterson was named Veterinarian of the Year by the VMA of New York City (2012).


Dr. Peterson has published more than 600 journal articles, book chapters, and research abstracts. He has held a number of editorial appointments, including a major textbook of Small Animal Endocrinology. With more than 450 teaching presentations to his credit, Dr. Peterson is a frequent speaker at veterinary and medical seminars both in the United States and abroad. In 2013, Dr. Peterson was named the Outstanding Speaker of the Year at the annual New York State Veterinary Conference.


Dr. Peterson is also very involved in organized veterinary medicine and veterinary continuing education. He was the founding member and first President of the Society of Comparative Endocrinology. He serves on the executive board of the New York City Veterinary Medical Association (VMA). Dr. Peterson previously served as President of the association and is currently the head of the continuing education program committee.


In 2001, Dr. Peterson founded Hypurrcat, a radioiodine treatment center for hyperthyroid cats in Bedford Hills, New York, located about 35 miles north of New York City. 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).


In 2009, Dr. Peterson opened an office on the Upper West Side of Manhattan in New York City. He sees endocrine patients in both the Bedford Hills office and the New York City clinic. Both clinics have Hypurrcat facilities for treating hyperthyroid cats with radioiodine.


In 2013, Dr. Peterson was appointed to the Editorial Board of the Journal of Feline Medicine and Surgery (JSFS), the leading scientific veterinary journal dealing with diseases of the cat.


In 2014, following a year of collaborative research with the staff veterinarians in the Departments of Internal Medicine and Radiology, Dr. Peterson was appointed Adjunct Professor of Medicine at the College of Veterinary Medicine at Cornell University.
