About the Veterinarian

Dr. Donald Thompson

Dr. Donald Thompson, owner of Elk Park Animal Hospital, grew up on a registered Holstein-Friesian dairy farm with nine siblings on the Canadian border of New York. In 1984, he graduated from Cornell University’s College of Veterinary Medicine and began a large and small animal practice in Vermont until selling that Northeastern practice in 2012 to relocate to Pagosa Springs.


Many years ago, his training in acupuncture and herbal medicine began and has flourished as an important facet of day-to-day practice here in Southwestern Colorado. Elk Park Animal Hospital is a truly integrative veterinary practice, utilizing traditional Western medicine and surgery as well as complementary diagnostic and treatment modalities appropriate on a case-by-case basis. Dr. Thompson has had the opportunity to lecture in China and has authored professional articles and textbook chapters related to both acupuncture and herbal medicine. In addition,Dr. Thompson regularly teaches at the famed Chi Institute of Traditional Chinese Veterinary Medicine in Florida.


Dr. Thompson has utilized acupuncture and herbal medicine on horses, cattle, dogs, cats, llamas, alpacas, rabbits, pet birds and chickens. These modalities open the door to many therapeutic options for a variety of species. Let us know if you have questions on how we might be able to help with your pet or ranch animals.
