Scott Hansen, DVM

Columbia Equine Hospital

Dr. Hansen has been interested in horses since his teens. He first pursued a career as a farrier in Nebraska after attending Oklahoma Farrier College. After being exposed to the equine veterinary medicine world while working for a year, Scott decided to become a veterinarian. He continued to work as a farrier while attending Iowa State University College of Veterinary Medicine until he graduated in 1980. He then moved to the Gresham area and opened a solo equine-only ambulatory practice in 1983, focusing primarily on race horses. Scott’s interest in lameness and surgery grew while working at the track. He opened his current hospital in 1985 with a surgical facility to be able to provide a higher quality of care for his patients. His practice has grown much larger than he had ever imagined with its emphasis shifting from racetrack work in the mid 1990’s to sporthorse and companion animal medicine and surgery. Scott has remained intrigued by equine medicine by staying up-to-date with the latest technologies and advances in the field. Throughout his practice life, Scott has found the most rewarding aspect has been the people he has met and the horses he gets to work with everyday. Dr. Hansen’s main interests have been lameness, surgery, farrier science and diagnostic imaging.
