Camille Torres-Henderson

Dr. Camille Torres-Henderson, DVM, DABVP, DAVCIM (Nutrition) attended Colorado State for her undergraduate and veterinary education. After she earned her DVM in 2001, she went into small animal private practice in Albuquerque, N.M. She joined Community Practice at the James L. Voss Veterinary Teaching Hospital in 2008 and earned her feline and canine DABVP certification in 2011. As a general practitioner, she has observed the power of preventive medicine. Seeing how preventing disease can be so much easier for a pet than treatment led her to explore the effects of obesity on companion animals and nutrition’s role in obesity management. Her enthusiasm for nutrition inspired her to seek additional training in the field of nutrition and she completed a residency in nutrition at CSU and became a Diplomate of the American College of Veterinary Internal Medicine-Nutrition in 2021.
