After suffering a severe head injury on March 26, dressage trainer Ricardo Amaya died on April 3 at Los Robles Hospital and Medical Center in Thousand Oaks, Calif. He was 47.

Mr. Amaya was training a horse when he suffered severe head trauma. He was alone in the ring at the time of the incident, so emergency personnel didn’t know exactly how he was hurt.

Mr. Amaya, of Amaya Farms in Thousand Oaks, was born in Colombia, South America and was introduced to horses by his father, Guillermo Amaya. During his time in South America, Mr. Amaya’s achievements included his title as the reserve rider for the Pan American Games dressage team and winning the Colombian Federation’s gold medal for best rider and horse team for three years. He also was an FEI-qualified judge for Colombia.

Arriving to the United States in 2000, Mr. Amaya trained at Far West Farms in Calabasas, Calif., for four years before beginning his own business. His many successes included the Dressage Association of Southern California’s Perpetual High-Point Trophy in 2004 and 2006.

Mr. Amaya is survived by his wife, Maria Amaya, and sons Claudio, 4, and Martín, 2. Memorial donations may be made to the Ricardo Amaya Family Fund, c/o Janice Romersa, 24232 Long Valley Road, Hidden Hills CA 91302.
