During his 41 year career with the American Quarter Horse Association, Don Treadway spent two thirds of his life promoting and marketing the world’s most popular breed of horse. Serving the most recent six years as its chief executive officer, Treadway has managed numerous industry initiatives, in North America and throughout the world. During his time at AQHA, he saw AQHA register more than four million American Quarter Horses, with membership reaching 353,000 worldwide.


He says his primary job description was to create programs and activities where people could connect with and then enjoy their horses. His greatest sense of accomplishment was witnessing the horse/person connection exceed expectations, literally thousands of times, whether it was success in the show or rodeo arena, or on the racetrack. Of particular satisfaction was seeing young people interact with their American Quarter Horses, learning life lessons which horses are experts at teaching. Guiding resurgence in the popularity of ranch horses and the development of competitions for different skills sets of riders were among his favorite projects.


A graduate of distinction of Oklahoma State University, Treadway resides in Amarillo, TX with Robbyn, his wife of 41 years. The couple has two children and three grandchildren.
