Dr. Ariel Fagen, DVM, DACVB
Board-Certified 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 86 of the most highly trained veterinary behavior specialists on the continent and one of two veterinary behaviorists in the state of Colorado.

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. 

Dr. Stacey Jones, DVM
Veterinarian - Practice Limited to Behavior
Fear Free Certified

Dr. Stacey Jones graduated from Colorado State University’s College of Veterinary Medicine in 2003.  After graduation, she completed a one year internship in Emergency Medicine and Critical Care at New England Animal Medical Center in Massachusetts. Returning to her native state of Colorado, Dr. Jones cultivated a special interest in Greyhound medicine, anesthesia, behavior and pain management.  She is proud to have participated in collaborative research into a life threatening elevation of blood potassium (hyperkalemia) that occurs in Greyhounds under anesthesia.

 

During her 16 years as a small animal veterinarian, Dr. Jones cultivated a practice focused on decreasing fear, listening to patient body language and including families in veterinary visits.  In this way, she could increase access to detailed care for all patients, especially those historically demonstrating anxiety or reacting aggressively.  Providing for medical needs through this behavioral lens led Dr. Jones on a journey to further understand and treat problem behaviors that were causing frustration and suffering for patients and their people, in and out of the hospital.  Dr. Jones furthered her education in the field of behavior and veterinary psychiatry through mentorship with field experts, attendance at the national Clinical Animal Behavior Conferences, and coursework on learning theory and applied behavior analysis, including Dr. Susan Friedman's course, Living and Learning with Animals.  Before coming to The Veterinary Behavior Center, Dr. Jones treated behavior cases within the scope of her general practice for 7 years.  She is currently a Fear Free certified professional and serves on the executive board of the American Veterinary Society of Animal Behavior as a member-at-large.  

Dr. Jones, her husband, and their two children, share a home with numerous dogs, horses, chickens, and aquatic creatures.

Mariah Dingus
Behavior Therapy Technician

Mariah began accumulating professional experience with animals at a young age as a volunteer keeper aid at the Houston and Cheyenne Mountain Zoos throughout high school and college.  In these positions, she taught animals from rhinos to grizzly bears to participate in cooperative vet care and learned a great deal about enrichment and the humane care of captive wildlife.  During her internship at the Penn Vet Working Dog Center in Philadelphia, she learned to apply her knowledge of training and cooperative care to dogs training for careers in search-and-rescue, law enforcement, and ovarian cancer detection. 

 

It wasn’t until her externship with veterinary behaviorist Dr. Lore Haug that Mariah discovered her true passion for a slightly different side of dog training: behavior modification.  In this position, Mariah assisted in addressing behavior cases from generalized anxiety to various types of aggression, honing her skills in identifying behavior problems and how to solve them benevolently and from the source, in the best interest of both dog and owner.

 

After graduating from Colorado College in 2019, Mariah took up a position at Canis Major Dog Training as a trainer.  There, in addition to teaching classes and training board-and-train dogs, Mariah worked one-on-one with clients whose dogs were struggling with behavioral issues from resource guarding to stranger danger.  Mariah’s favorite part of the job was being there to support her clients throughout their behavior plans and building a relationship of trust and open dialogue along the way.

 

Mariah shares her home with a perfect mutt named Peanut who literally wandered into her life. Peanut has given a hands-on opportunity to learn the ins and outs of separation anxiety and helps Mariah empathize with every client who owns a squirrel-obsessed dog.
