Our Veterinarians


Dr. Glen Wilkinson

Dr. Wilkinson knew at an early age that he wanted to be a veterinarian. It all started when he was working cattle with his dad, Ed Wilkinson, and young Glen was able to give his first of many shots. The seed that was planted that day grew and now Wilkinson Veterinary Clinic sees thousands of animals annually.

Glen attended Falfurrias High School and graduated in 1974. He was involved in the high school band and played the trumpet. Much of his time was taken up by his sacrifice to work on the family farm to help support his family after the loss of his father.

Glen started vet school in 1979 at Texas A&M College of Veterinary Medicine. His first child was born not long after starting school. Over the next few years Glen and Debbie worked hard to keep their marriage strong and were blessed with two more children. In 1982, Glen earned his Doctorate in Veterinary Medicine.

The same week after graduated, Dr. Wilkinson and his family moved to Premont, Texas and started Wilkinson Veterinary Clinic. Working out of his garage with his truck and minimal supplies, Dr. Wilkinson worked many long hours by himself to support his family. Debbie assisted him with a much of the paperwork and accounting. After about two and a half years, in 1985, Dr. Wilkinson built the building where Wilkinson Veterinary Clinic now operates and continues to operate as it has for over 35 years.
