Graduated from Colorado State University in 1980. He started his first clinic in Flagstaff in 1981. He currently spends most of his time in Tucson where he also has a clinic, established in 1995.

Flagstaff is still his first love, and he has maintained a two-vet practice in town since 1990. Dr. Livingston named the vet clinic after the Navajo word Kaibab, which means upside down mountain. He is not afraid of any species and has a special fondness for bearded dragons.
