Peterman and her team of Brittany Tran, Becca Konschuh and Kristine Anderson won a silver medal skipping Alberta at the 2011 Canada Winter Games, losing to British Columbia's Corryn Brown in the final. The next season, the team represented Alberta at the 2012 Canadian Junior Curling Championships. They won the event, defeating Manitoba's Shannon Birchard rink in the national final. This qualified the team to represent Canada at the 2012 World Junior Curling Championships. After posting a 6–3 round robin record, the team lost to Russia's Anna Sidorova in a tie-breaker match, thus failing to make the playoffs. In 2013, her rink failed to even make the Canadian Juniors, having not even made the playoffs in the Alberta playdowns. In 2014, her last year of junior eligibility, Peterman's team lost in the Alberta junior final to Kelsey Rocque, who would go on to win that year's World Junior championships.
