Career
DePiero coached the Saint Michael"s Buzzers to two consecutive Frank L. Buckland Trophies in the 2004-2005 and 2005-2006 seasons. DePiero became the head coach of the Generals late in the 2007-2008 season, as Brad Selwood stepped down from the position. DePiero, who was an assistant coach, was promoted to become the head coach, and guided Oshawa to a 5–4–7 record in their last 16 games, as the team finished in second place in the East Division, and qualified for post-season play.
The Generals then made it to the Eastern Conference finals before they were eliminated by the Belleville Bulls.
The Generals struggled in DePiero"s first full season behind the bench, as the club began to rebuild, which included trading leading scorer John Tavares, Michael Delegate Zotto and Daryl Borden to the London Knights for a package of three players and six draft picks. Oshawa finished the season in ninth place in the Eastern Conference, failing to qualify for the playoffs.
In 2009-2010, the Generals once again struggled, finishing with a 24-39-3-2 record, and missed the playoffs for the second consecutive season. He has recently been relieved of his duties as head coach and General Motors of the Oshawa Generals and is now coaching Varsity hockey at Saint Michael"s College in Toronto.
