Dr. Sarah Appleby

Dr. Sarah Appleby was born and raised in Tucson, Arizona, where she worked as a large animal veterinary technician before deciding to attend the University of Wisconsin for veterinary school. During school, she spent many hours working with local equine veterinarians, and was introduced to the Equitarian Initiative, a group of equine veterinary volunteers. After 4 years of working with this organization, she was asked to lead a class on the Cheyenne River Reservation (South Dakota), and will continue organizing annual volunteer trips to this reservation. In addition to volunteer work, Sarah has a special passion for complementary therapies, spurred by her own horse’s severe head trauma and chronic back issues. She is certified in veterinary acupuncture and veterinary spinal manipulation (chiropractic treatment). In her free time, Sarah enjoys hiking, skiing, riding her horse, and overall spending time outdoors in beautiful Colorado!
