Dr. G. David McCarroll DVM

“Christian, husband, father, American, horseman, veterinarian, scientist and snow skier in that order.”  This list reflects the inspiriting priorities of George David McCarroll DVM.


He was born on March 4, 1950 in Freeport, TX. He was the oldest son of four, born to George Fentress McCarroll and Patricia Anne (Mackey) McCarroll. Because of his passion for the equine industry it was logical for David to attend Texas A&M University in College Station, TX.  He graduated Cum Laude when he completed his Doctor of Veterinary Medicine degree in 1973.

He was Board Certified in 1979 through the American College of Veterinary Internal Medicine. He taught equine medicine and surgery at Oklahoma State University and the University of Tennessee before settling into private practice, first in Texas with his brother, John McCarroll, DVM, and then in Oklahoma in 1984.

In 1994, Dr McCarroll opened Interstate Equine Services, Inc. He was truly concerned with promoting health and advancements in the equine industry, by caring for his patients in the most comprehensive and careful manner.  Committed to furthering the field of Equine Medicine, he garnered more than 50 hours of continuing education each year.  His clients received the same trustworthy equine medical expertise for their horses whose careers ranged from prestigious horse show athletes to the beloved backyard pet.

He devoted his life to the horse community and embraced every opportunity to contribute. He was a member of the AQHA Equine Research Committee on horse health. He participated in many research studies and shared his wealth of information freely with others in the equine health field. Dr David was a board member and an officer of the Oklahoma Quarter Horse Association.

Dr David, an active breeder of AQHA show horses, was an enthusiastic spectator while his wife Trina and Jesilynn competed. McCarroll was select as the Official Veterinarian for the American Quarter Horse Association World Championship Horse Show from 2005-2011.


He was a practitioner, researcher, and educator of Equine Veterinary Medicine for 39 years. Dr. McCarroll said his, “professional goal is to provide the best possible care for my clients and their equine companions while furthering the advancement of equine medical research for as long as I am able.”

He certainly accomplished that…and an abundance of the other goals he set for himself.


The equine industry suffered a tremendous loss when Dr McCarroll passed away on May 25, 2012.
