Mack Weaver was raised in Colorado in a horse show family. Growing up showing in many different disciplines, he found his niche in the reining industry. He has been training reining horses for the public for the past 16 years.  Mack's wife Ashley, a Utah native, also grew up around horses. Together they run Weaver Performance Horses out of Graceland Equestrian Center, located in the beautiful mountain valley of Morgan, UT. Mack does the training and Ashley does all the behind-the-scenes work.

​

Mack enjoys futurity and derby horses, but his favorite aspect of the reining business is helping non-pro competitors reach their goals. Mack believes that seeing a rider "get along great with your horse" is the most rewarding feeling.
