Biography

Dr. Fagen graduated from Tufts University Cummings School of Veterinary Medicine in 2013. She went on to complete an intensive one-year rotating small animal internship at Wheat Ridge Animal Hospital. In 2017, she completed a 3-year residency in the American College of Veterinary Behavior at Behavior Vets of Colorado and Florida Veterinary Behavior Service. In 2018, Dr. Fagen became a Diplomate of the American College of Veterinary Behavior, the highest level of veterinary behavior specialty degree possible. This degree makes her one of 86 of the most highly trained veterinary behavior specialists on the continent and one of two veterinary behaviorists in the state of Colorado.

Outside of the office, Dr. Fagen has lectured in the US and internationally. She has conducted research studies in shelters, hospitals and wildlife breeding centers and has published in the Journal of Applied Animal Welfare Science and NAVC Clinician’s Brief. Dr. Fagen was awarded the American Veterinary Society of Animal Behavior Student Excellence in Applied Animal Behavior Research Award and the Tufts University Cummings School of Veterinary Medicine Best Field Research Award for her work training elephants to participate in their own medical care in Sauhara, Nepal.


A Colorado gal to the core, Dr. Fagen plays in the mountains hiking, camping and downhill and cross-country skiing. She loves to travel with her adventuresome husband, giggle with her young son and share meals with friends. The four-legged love of her life, Libby, was with her through her veterinary education and taught her a great deal about living with and loving a dog with aggression problems.
