Dr. Mullen 2015 Website

Dr. Katie Mullen grew up in Evergreen and spent her summers on her family’s cattle ranch near Paonia. A good deal of her childhood was spent trying to catch her horse, a flea-bitten gray Arabian gelding. When convinced to be caught, he served as a sure-footed ranch horse or dressage show horse depending on the day.

Dr. Mullen spent many years taking advantage of the numerous educational opportunities at Cornell University. The long, cold, gray winters of Ithaca, NY served as the ideal location to study Animal Science (B.S. with Honors), Agricultural Economics (M.S.) and Veterinary Medicine (DVM and Large Animal Internal Medicine Residency). Before obtaining her veterinary degree, Dr. Mullen was as a trade economist in Washington, D.C. However, a yearning to be closer to the horses she had always loved, motivated her to apply to veterinary school.

Following vet school, Dr. Mullen was an associate at a large animal ambulatory practice in Central Massachusetts. While she enjoyed the challenges and rewards of ambulatory practice, one day she received a call inviting her back to Cornell to pursue a residency in Large Animal Internal Medicine, an offer she couldn’t refuse. She achieved board certification in 2014 and has been an Instructor of Large Animal Medicine at Cornell for the past year. During Dr. Mullen’s residency and instructorship, she has had the opportunity to present research findings at the American College of Veterinary Internal Medicine Forum in Nashville, TN and the Colic Symposium in Dublin, Ireland, and has published research findings in several veterinary journals. She received advanced training in transboundary animal diseases and has had the opportunity to teach both veterinary students at Cornell and veterinary agents in Haiti. Her special interests include equine neonatology and gastroenterology, but she truly enjoys all aspects of internal medicine.

Dr. Mullen is absolutely thrilled to be returning home to Colorado to join the Littleton Equine Medical Center team. She looks forward to working with you to provide exceptional care for your patients and clear, open communications with our clients.
