Our Veterinarians

Brian McKee, DVM

Dr. Brian McKee was born in Santa Fe, New Mexico and raised on a ranch 30 miles south of town. Throughout his youth on the ranch, he dreamed of becoming a veterinarian. Upon graduating from Kansas State University College of Veterinary Medicine in 1982 he opened up a small ambulatory mixed animal practice outside Santa Fe. A yearning to concentrate on small animal medicine took him to California where he purchased Sierra Veterinary Hospital in South Lake Tahoe. Wanting to move closer to family, Dr. McKee sold his hospital in California in 1992 and purchased Aspen Arbor Animal Hospital in April 1992. Over the past 29 years of practice, he has gained a wealth of knowledge and experience in small animal surgery and medicine. The simple values he learned as a child while growing up on the ranch in New Mexico are the foundation of his practice principles. Dr. McKee and his wife, Charlotte, have two children, two grandchildren and a Border Collie named Mia.

Ann Brown, DVM, CVA

Dr. Ann Nelson-Brown graduated as valedictorian from high school and went on to attend Michigan State University. Ann’s undergraduate work focused on Animal Science and she graduated with her Doctorate of Veterinary Medicine from MSU in 1995. She then attended Colorado State University as an anatomic pathology graduate student. She started work as a clinical small animal veterinarian in the Denver area in 1997 and has continued to serve the Denver metro community as a small animal veterinarian ever since. In 1999, Ann received special recognition for her humanitarian efforts in starting and maintaining a not-for-profit program aimed at helping abandoned, injured and/or sick animals in need of medical attention. Ann volunteered many hours towards caring for and earning money for diseased abandoned animals. She obtained certification in veterinary acupuncture from CSU’s acclaimed program in the spring of 2009, and has successfully incorporated acupuncture into her veterinary medical and surgical practices. Ann lives in Westminster with her husband, Doug, two children, and their dogs, Buster, Tehya and Pippin. She enjoys reading, creative writing, Kundalini Yoga, hiking and listening to music in her spare time.

Kristin Harrison, DVM

Dr. Harrison received her B.S. degree in Animal Science from the University of Florida and her Doctor of Veterinary Medicine degree from the University of Tennessee College of Veterinary Medicine in 2014. She recently moved to Colorado because of the outdoors and the lifestyle we all enjoy. Dr. Harrison’s pets are two cats, Daniel and Luna. Daniel was a rescue from a previous vet hospital Dr. Harrison worked at, & Luna was a shelter rescue kitty. We’re very excited to have Dr. Harrison on the team – please give her a warm welcome next time you see her in the hospital!
