This path was originally supposed to culminate in a PhD in Marine Biology focusing on research, which landed her in two internships at Mote Marine Laboratory in Sarasota, FL where she spent time rehabilitating sea turtles, manatees, and pygmy sperm whales. It was during these internships working alongside veterinarians who volunteered in the lab that her true calling became apparent. Dr. McCafferty subsequently attended and graduated from Virginia- Maryland regional College of Veterinary Medicine in 2000.
