Dr. Keith, our Radiologist and Medical Director, has always been committed to delivering excellent veterinary care to families in his home state of Arizona. The opportunity to join the vet specialist team in Mesa (named Mesa Veterinary Hospital at that time) not only allowed him to bring his expertise back home, but also allowed him to help shape VCA Animal Referral & Emergency Center of Arizona and eventually lead the medical team.

A 1990 graduate of the University of Arizona, he obtained his DVM in 1994 from Colorado State University. After practicing in Flagstaff for 2 years, he completed a 3-year residency in radiology at the University of Pennsylvania (Penn Vet); and served on the faculty for a year as a Lecturer and Alternative Imaging Fellow (also at the University of Pennsylvania) where he advanced his training in both ultrasonography and computed tomography (CT). He is board certified by the American College of Veterinary Radiology. Professionally his interests include contrast radiographic studies, ultrasound, CT and MRI.
