I was born into a household full of animals – everything form dogs to lizards! I had pet rats, rabbits, tortoises, snakes and tarantulas as a kid, and I thought my dog was my sister. With my love of science and the outdoors, there seemed no other path to follow! I now find myself most intrigued with the human interactions involved in veterinary medicine – how people bond to their pets and manage the emotional difficulties in caring for sick pets, and how to lead and manage teams of people dedicated to caring for people and their pets. I have been so completely blessed by this diverse profession!” Bonnie lives with her Border Collie, Pete; Australian Shepherd, Zeke; Catahoula cross, Teague; plus her 3-legged rescue kitty Vinne.
