The Stonewall Sporthorse is a unique American warmblood developed by International
Champion horseman and World Champion breeder, Michael Muir at his Stonewall Stud. His horses have established world sales records at auction, earned National Grand Championships in the United States, Canada, Australia and New Zealand, set world records racing (as well as setting sire and produce records) earned national titles in jumping and performance, and qualified seven times to represent the United States in World Championship carriage driving competitions in Great Britain, France, Austria Germany and Hungary. Over the course of his life, Muir has been an avid trainer and exhibitor but has found his greatest satisfaction and success as a
renowned breeder of champion horses.

Today, Michael serves as the Founder and Director of Access Adventure, headquartered at the Solano Land Trust’s historic Rush Ranch. The Stonewall Sporthorses seen at Rush Ranch today support the work of Access Adventure, enriching the lives of people with disabilities and other underserved members of our community by providing outdoor recreation, open space access, education and therapy through a working partnership with horses.
