She also has one cat, Livingstone who she hand raised as a baby and five turtles Teddy, Spike, Sunny, Burtle, and Shemus. She originally entered into Veterinary Medicine due to a long time desire to go to vet school but decided that she preferred the business side over the medicine. Her favorite part of her job is being able to support the medical staff in their efforts to diagnose and treat the many patients that come into the clinic. Nothing thrills her more than a seeing a happy reunion between a pet and their parent(s) after a stay at the clinic.
