His first was in 2003, throwing fourth stones for a team skipped by Daniel Sherrard (no relation).^[5] The team represented New Brunswick at the 2003 Canadian Junior Curling Championships, where they finished with a 6–6 round robin record, missing the playoffs.

The next season, Sherrard won another provincial junior title, this time skipping a team which also consisted of Jason Roach, Darren Roach and Jared Bezanson. The team played in the 2004 Canadian Junior Curling Championships, where they made the playoffs after posting a 9–3 round robin record, tied with two other teams for first place. In the playoffs, they beat Manitoba's Daley Peters rink in the semifinal and then Newfoundland and Labrador's Matthew Blandford team to claim the championship.^[3] The team then went on to represent Canada at the 2004 World Junior Curling Championships. There, the team finished with a 5–4 round robin record, tied with South Korea's Kim Soo-hyuk for fourth place. They lost to the Korean team in a tiebreaker.
