Granite Performance Horses is located in Collbran, a small town in the beautiful Plateau Valley on the Western Slope of Colorado. GPH is named after my late Granddad’s ranch in Tres Piedras, NM, from whom the Reverse D Diamond brand originated. Our goal is to create versatile quarter horses to use on the ranch, the show pen, the arena or just for lifelong companions. We are continuing to build a program that uses the Driftwood and Blue Valentine bloodlines as the foundation and then selectively out-crossing with some of the performance lines of today. Thank you for stopping by the website and please come back again as we develop a lasting legacy.
