Born in Peterborough, Ontario, Epping was a top junior curler, having won the Ontario Junior championship in 2004. At the 2004 Canadian Junior Curling Championships, his team finished with an 8-4 record, just out of the playoffs. He won the 2006 Canadian Mixed Curling Championship with Julie Reddick, Scott Foster and Leigh Armstrong. He won the 2007 provincial mixed as well, but could not defend his national title.
After Juniors, Epping played third for Nick Rizzo until switching positions with Rizzo in 2006, and thus skipping the team. However, in 2007 he was picked up to play third for Olympic silver medallist Mike Harris. He'd only play one season for Harris before joining Wayne Middaugh's rink at second in 2008. With the Middaugh rink Epping won the 2008 National, his first Grand Slam victory. The team also played in the 2009 Canadian Olympic Curling Trials, where they finished with a 2-5 record. In 2010, Epping parted from Middaugh to form his own team.
Epping and teammates Scott Bailey, Scott Howard and David Mathers won the 2012 Players' Championship, Epping's second Grand Slam title of his career, and his first as skip. This win helped him accrue enough CTRS points to qualify for a direct spot at the 2013 Canadian Olympic Curling Trials. At the Trials, his rink (which replaced Howard with Collin Mitchell) won just one game, and finished last. Following the season, Epping formed a new team with Travis Fanset, Pat Janssen and Tim March. Mat Camm replaced Fanset in 2015.
