He is one of four veterinary cardiologists that are located in Atlantic Canada. Dr. Orr is a 2004 graduate from the Atlantic Veterinary College at University of PEI. He completed his one-year rotating small animal internship at the Ontario Veterinary College at the University of Guelph in 2005 and practiced in both general small animal practice and emergency medicine in the Toronto area from 2005-2007.

Dr. Orr completed a 3-year cardiology residency at the University of Guelph in 2010 and became board-certified by the American College of Veterinary Internal Medicine (ACVIM) that same year.
