Sarah & Clayton Martin

Sarah & Clayton.jpg

Sarah & Clayton come regularly to both the Grand Junction and Montrose areas. Their program emphasizes the systematic development of both horse and rider through an approach that blends the two worlds of Dressage and Natural Horsemanship in a natural fit of balance, harmony, and "horse sense." Motivated students, they both are constantly seeking education from many sources, and draw on their background with nearly every style of English and Western riding to help educate their students. 

Sarah, a US Dressage Federation Gold Medalist and a member of the Faculty for the US Dressage Federation Trainer and Instructor program, has been teaching and training National and International level riders and their horses for over 30 years. 

Clayton, a USDF Silver Medalist and a USDF Certified Instructor through 4th level, works with developing horses from green to Grand Prix in long lines as well as under saddle.
