Marvin Earl "Monty" Roberts MVO (born May 14, 1935) is an American horse trainer who promotes his techniques of natural horsemanship through his Join-Up International organization, named after the core concept of his training method. Roberts believes that horses use a non-verbal language, which he terms "Equus," and that humans can use this language to communicate with horses. In order to promulgate his methods, Roberts has authored a number of books including his original best-seller, The Man Who Listens to Horses, and regularly tours with a live demonstration. He runs an Equestrian Academy in Solvang, California and an "online university" to promote his ideas.
