While in school, she worked at various small animal practices, and participated in Veterinarians Without Borders in Kenya. She spent some of her final-year rotations providing veterinary services on the isolated ice roads in the Sathu region of the NWT, learning how to perfect the art of the blow dart at the Calgary Zoo, and evaluating parasite loads in wolverines at Alberta Fish and Wildlife.
