Doctors
Dr. Kristi Falk
Kristi is originally from North Dakota where she attended North Dakota State University for her undergraduate studies in microbiology. While in school, Kristi was a zookeeper at the Red River Zoo—this is where her passion for exotics was sparked. Kristi later attended Iowa State University, graduating with a special interest in exotic medicine and surgery. She began her career at a small animal and exotic hospital in Los Angeles County before moving and joining The Animal Doctor team in 2016. Kristi still has a special interest in exotics due to the complex diagnostic challenges they can bring. Because of her diligent attention to detail in exotics, she is also a fantastic dog and cat veteterinarian. Her other medical interests include soft tissue surgery, neurology, and ophthalmology. In her spare time, Kristi enjoys hiking and camping with her husband and their two dogs. She also likes to relax by curling up with her two Bengals and a good book.
Dr. Liz Filbert
Liz graduated from Colorado State University College of Veterinary Medicine where she chose to study both small and large animal medicine. During veterinary school, she sought out further education to become a Certified Veterinary Medical Acupuncturist. She and her husband, Barney, both grew up in Broomfield—Go Eagles! After graduating vet school, Liz returned to her hometown and is now an associate veterinarian for The Animal Doctor, where she practices small animal medicine. Together, Liz and Barney share their lives with a 55 lb. hairless dog, Bod; a Great Dane, Romeo; two cats, Gizmo and London; and two horses, Reiny and River. While she loves all animals, she especially enjoys working with giant breed dogs and micro and teacup pigs.
Dr. Ashlyn Spring
Ashlyn was born and raised in Durham, North Carolina. As an undergrad at Elon University, she received her B.S. in biology. From a young age, Ashlyn knew that she wanted to work with animals. She grew up spending much of her time volunteering at animal shelters, the Duke Lemur Center, and a local big cat sanctuary. It wasn’t until college, when she began working as a vet technician, that she discovered her true passion for veterinary medicine. After graduating from Elon, Ashlyn moved to Colorado where she joined the The Animal Doctor team as a tech for two years. She then left to attend veterinary school at the University of Illinois. Upon receiving her Doctor of Veterinary Medicine degree, Ashlyn was drawn back to Colorado by her love of hiking, skiing, camping, and the amazing friends she had made through The Animal Doctor. Ashlyn now lives in Denver with her two dogs, Lennon and Charlie, and her three-legged cat, Hiccup. She spends her days-off outside, whether it’s hiking with her pups, picnicking in a local park, or enjoying a beer at a local brewery.
Dr. Chad Stewart
After receiving his Master of Science and Doctor of Veterinary Medicine degrees from the University of California-Davis in 1999 and 2003, Chad practiced small and large animal medicine and surgery in New Mexico and California. In 2007, he moved to Colorado where he has been practicing small and exotic animal medicine and surgery at several clinics along the Front Range. Chad really enjoys solving problems, particularly in difficult internal medicine and surgical cases. When he’s not working, Chad spends time with his two sons and two dogs. He is also an avid trail runner, snowboarder, and musician—playing guitar and drums.
