Dunnam aged out of juniors after the 2013–14 season and Stopera joined the United States Curling Association's (USCA) Junior High Performance Program. Stopera was added to the Korey Dropkin rink at the lead position, joining Tom Howell, Mark Fenner, and alternate Luc Violette. Despite the new team, the result at the 2015 Junior Nationals was a familiar one, another silver medal. The team also competed in the United States Men's Championship, where they finished 7th. The next season, Stopera formed a new team, adding Luc Violette at third, Steven Szemple at second, and William Pryor at lead. The new lineup earned bronze at the 2016 Junior Nationals.
