Veterinary Pioneer Dr. W. Thomas Riddle Passes Away at Age 74

Riddle was known for his veterinary expertise coupled with integrity and kindness, making him a revered figure in the equine community. His longtime friend John Williams described him as a “quiet giant” and characterized him as highly professional and a pleasure to be around. Riddle, along with partner Bill Rood, began their practice from humble beginnings in a garage in Chevy Chase, Lexington, eventually establishing Rood and Riddle as one of the most respected equine surgery practices in the United States, if not the world.

Born on June 7, 1952, in Greenville, South Carolina, Riddle initially considered a career in human medicine but found it uncomfortable, and returned to his true passion—veterinary science. He graduated from the University of Georgia in 1978 and started his career at Spendthrift Farm, where he impressed his peers with his dedication and skill.

Williams recalled that Riddle arrived at Spendthrift as a young intern during harsh winter months, yet he showed perseverance that foreshadowed his future success. Riddle quickly gained respect in the field and formed lasting partnerships, including his eventual collaboration with Rood, which grew to encompass multiple locations and many veterinarians.

The partnership was marked by a shared vision and a commitment to quality care. Riddle’s focus was on the hands-on treatment of animals, while Rood managed the business aspects. Their dedication led to significant growth, as they transitioned from operating out of a garage to a larger facility while maintaining high standards of veterinary care.

Throughout his career, Riddle received numerous accolades, including leadership roles in the Kentucky Association of Equine Practitioners and the Society for Theriogenology. He was also recognized for his contributions to the veterinary community with several prestigious awards.

Riddle's impact transcended professional accolades; he was a dedicated family man. He married Margaret Alexander, whom he met while working at Spendthrift, and they had three children together. Riddle maintained a commitment to family life while balancing a demanding career.

In addition to his professional achievements, Riddle was instrumental in helping to address Mare Reproductive Loss Syndrome in 2001, displaying a blend of scientific acumen and hands-on veterinary skills.

He is survived by his wife, Margaret; his children, Peden Riddle Fraley, Alexander Landstreet Riddle, and William Davis Riddle; his siblings; and several grandchildren. He was preceded in death by his brother, Herbert Earle Riddle, Jr.

Family and friends can gather from 4 p.m. to 7 p.m. on Monday, September 28, at Clark Funeral Home in Versailles, Kentucky. A memorial service will take place at 11 a.m. on Tuesday, September 29, at the Church of the Ascension in Frankfort, Kentucky. Memorial contributions may be made to Bluegrass Farms Charities.
