Board-Certified Oncologists

Board-certified veterinary oncologists specialize in the diagnosis and treatment of cancer in animals. The American Veterinary Medical Association (AVMA) has developed a system of specialty colleges that certify specialty trained veterinarians.

A board-certified veterinary specialist has completed extensive post-graduate study and training, has demonstrated clinical competency under close supervision, and has passed a comprehensive examination in the specialty. Board-certified specialists are referred to as “Diplomates” of their specialty college.

At the present time there are fewer than 400 board-certified veterinary medical oncologists and fewer than 100 board-certified veterinary radiation oncologists in the country. We are fortunate to have several of both, and they are dedicated members of our team at Southwest Veterinary Oncology, PLLC.
