Greg Piske, DVM

Dr. Greg Piske has always been drawn to medicine and animals, which is what led him to pursue a career in veterinary medicine in the early ‘70s. He earned his DVM from the University of Tennessee in 1980 and became a veterinarian at Colony Animal Hospital in 1983. With his 30+ years of experiences in the field, he loves experiencing the human/animal bond and all of the emotions and quirks that come with it. He also enjoys being in a position that allows him to improve the quality of life, both for pets and their owners.

In addition to his training at the University of Tennessee, Dr. Piske regularly completes continuing education courses in surgery and internal medicine. For many years, he was a Diplomate of the American Board of Veterinary Practitioners (ABVP), which means he was a boarded specialist in canine and feline medicine—one of only 13 in the state. To earn the status of an ABVP Diplomate, Dr. Piske undertook additional studies and examination to acquire board certification by the American Board of Veterinary Practitioners. This decision proves his exceptional knowledge and expertise in various animal species. Even though his diplomate status has officially worn out, he still maintains his specialty knowledge in cat and dog care. Additionally, he is involved in several veterinary organizations to include membership in the American Veterinary Medical Association (AVMA), the American Animal Hospital Association (AAHA), as well as the local and state associations.  He is also a Charter Member of Veterinary Management Group 5 (VMG 5).
