His personal best result is 5.70 metres, achieved in 2000. This is the current St Lucian record. He also holds the St Lucian records in decathlon, 110 metres hurdles, 4 x 100 metres relay and 4 x 400 metres relay. In 1998, Dominic established his national indoor record of 5.55 m in Flagstaff, Arizona. A graduate of University of Arizona, he has been described by then-coach Dave Murray as "the best all around athlete we've ever had at the university."  Dominic, a past Sportsman of the Year recipient in St Lucia, won a silver medal for St Lucia at the 2008 CAC Championships in Cali, Colombia. In collaboration with journalist Terry Finisterre, Dominic also set up a College Athletic Scholarship Program which benefitted more than 30 St. Lucian athletes, one of who went on to become a 2004 Olympian.
