About Us


Our Roots

Canyon Large Animal Clinic was established in 1986 by veterinarian and founder Dr. Marc Horrell . Dr. Horrell provided extraordinary services for Sonoma county horses, cattle, and clients until his well deserved retirement in 2017. We are pleased to still have him around the clinic for consultation services. If you're lucky you may see him catching some waves at the beach!


Dr. Katie Prince DVM

Dr. Katie Prince was born and raised in Southern California. She moved North to Pullman, Washington where she attained her veterinary degree from Washington State University, College of Veterinary Medicine. She then headed East where she completed her internship with the prestigious Rood and Riddle Equine Medical Center in Lexington, Kentucky. While Dr. Prince was able to work with some of the worlds greatest racehorses and breeding farms in Kentucky she had a longing to head back West. She returned to Ventura County where she established her own highly successful private practice in 2006. After providing the highest quality of care to her horses and clients for 10 years the opportunity to move to beautiful Sonoma County could not be turned down. Dr. Katie Prince is excited to continue providing excellent care and services to the horses and clients of Canyon Large Animal Clinic.
