Moccio enrolled at the University of Western Ontario where he studied performance and classical piano studies under instructors John Paul Bracey and Jack Behrens. After completing a Bachelor of Arts degree in composition and piano performance in 1994, he was accepted into the famed Berklee College of Music. However, he chose to focus on developing his professional career and instead signed a publishing deal with Sony/ATV Music Publishing. During the early years of his tenure at Sony/ATV, Moccio worked as a session musician, in-house producer, arranger and composer, attending rehearsals of the Toronto Symphony Orchestra, and playing in Toronto jazz clubs and hotel lounges, notably the Four Seasons Hotel's La Serre.
