Our Team
Dr. Ariel Fagen, DVM, DACVB
Veterinary Behaviorist
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 85 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, giggling with her young son and sharing 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. 

Anita Hurley, CTC, CBCC-KA
Behavior Therapy Technician

Anita's role as a veterinary assistant began in 2002 and inspired her interest in animal behavior, prompting her return to studies. Her proudest accomplishments include obtaining her CTC (certified training consultant) and CBCC-KA (canine behavior certified consultant- knowledge assessed) certifications. She has over a decade of experience teaching a variety of group classes with dogs and their families as well as providing private consultations for complex canine behaviors as the Supervisor of Animal Training & Behavior at the Humane Society of Boulder Valley.  Anita’s compassion for people and their animal companions is the driving force for her commitment to helping enhance the human-animal bond.  Buster, her English Bulldog, and Pinky, her Boston Terrier/French Bulldog mix, are the two dogs in her life that continue to teach her lessons in giving and receiving joy every single day.
