Mark grew up in Puerto Rico riding ponies and horses at the local stable. He excelled in the jumper ring, showing in local competitions on the island and traveling with his children's jumper team to the States. He went to high school in Connecticut at Kent Boarding School and was competitive on their riding team. Upon graduation he headed to Colorado to attend Denver University.
His equestrian career evolved as he began working for some of Colorado's largest show barns as an "up-down" instructor. He then decided to move on and open his own business and facility in 1996, where Three Pines Farm still stands today. If you decide to ride at Three Pines Farm you will have the opportunity to train with an excellent horseman and teacher.
