Summit’s Stars are a group of talented up-and-coming riders in a range of disciplines.  Each star shows exceptional talent in their chosen area of specialization and values the importance of a strong nutritional program in the success and well being of their horses. Summit works closely with each of these riders throughout the season to insure that each horse’s diet and nutritional management meets their individual needs.  In turn our Summit Stars are assured that their horses are at peak performance when it matters most.

We encourage you to learn more about these talented riders and to read the stories of their individual horses and the approaches we take to insure they are at the top of their game and ready to shine.
