Mark developed a tumor that would eventually lead to an amputation when he was 14 years old in order to prevent a fatal outcome. Mark had grown up playing soccer, baseball, and swam competitively since he was just four years old.
Swimming remained active in Mark’s repertoire as he endured chemotherapy and eventually translated into an avenue for him to compete at the Paralympic level.
Mark eventually progressed to Paratriathlon and has won two national championships, as well as represented the US in multiple international events, most recently taking 2nd at the Rio de Janeiro ITU World Paratriathlon Event and 4th at the ITU World Paratriathlon Grand Final in Chicago. Mark is currently ranked 3rd in the world and also represents CAFs Elite Paratri Team. Mark has qualified and will be competing on Team USA during the 2016 Paralympic Games in Rio, the first Paralympics where Paratriathlon will be featured.
