Dr. Rob Bruner

Dr. Rob Bruner

Owner/Chief Veterinarian Dr. Rob Bruner grew up around animals and veterinary medicine. His father was a longtime veterinarian in Harlowton, Montana. Pursuing a love of medicine, Dr. Rob graduated from the University of Montana then served in the U.S. Peace Corps in Malawi (Africa) for more than two years. After graduating from Colorado State University’s Veterinary Medicine & Biological Science program in 2000, he practiced for three years at an all-animal clinic in Flagstaff, Arizona. In 2003, he brought his new bride, Cynthia, back to the state he loves. Dr. Rob and Cynthia developed a plan for a small animal clinic that would meet all the needs of small animals in a compassionate environment, and in 2005 they built Big Sky Pet Center. At home Dr. Rob is surrounded by animals and a couple two-legged critters (Kyra and Ret), and no matter what time of year it is, when he’s not home you can bet he’s fishing.

Dr. Davis has been practicing Veterinary medicine for 13 years with a special interest in feline medicine and surgery. Originally from Minnesota, she moved to Jackson Hole, Wyoming at the age of 19 to work as a Wrangler and drove a team of Clydesdale horses for sleigh rides. She then moved to Arizona and worked as a “Hot Shot”, fighting wild land fires for a season. After having her “out west” adventures, she returned to Minnesota and earned her DVM at the University of Minnesota college of Veterinary medicine in 2005. After graduation she owned a mixed animal practice in Minnesota and traveled on weekends to Fargo North Dakota to serve as a Veterinarian at the horse racetrack. After doing this for numerous years, the “west” started to call her name and she moved to Montana, where she has lived for 7 years now. In her spare time Dr. Davis enjoys the outdoors, riding her horses in the mountains, and spending time with her animals and family members in Bozeman, Montana.
