Why did you become a veterinarian?

Veterinary medicine allows me to combine a strong interest in the science of medicine with the desire and ability to help animals and people.

What’s your favorite animal?

It is difficult to choose a favorite animal; however, I have always had a special interest in bison, polar bears, big cats/domesticated cats, dogs/wolves, and sharks.

Arch Robertson, DVM, OwnerDiagnostic Imaging & Mobile Ultrasound at VETMED

Arch Robertson, DVM, began teaching himself veterinary ultrasound in 1985 at his former small animal practice, East Valley Veterinary Hospital in Mesa, Arizona. He quickly realized the non-invasive nature of this technology and began offering his services to other veterinary practices throughout metropolitan Phoenix. Dr. Robertson became the first veterinarian to offer mobile ultrasound services in Arizona. After a decade of pioneering work in this burgeoning field, he founded VETMED in 1995.

Dr. Arch Robertson earned his doctorate in veterinary medicine from The Ohio State University Veterinary School in 1983. He earned his bachelor’s degree from Ohio State University in 1978. He is a member of the Arizona Veterinary Medical Association and the American Veterinary Medical Association.

The Phoenix Zoo as well as numerous rescue organizations, are the grateful recipients of Dr. Robertson’s philanthropy as he has generously donated his time performing ultrasound for these organizations.

In his spare time, Dr. Robertson enjoys hiking, working out at the gym, paddle boarding, traveling, biking and playing ball with his Labrador, Clifford. He is a devoted father to Kimberly, Greg and Cole.
