[8] Representing the United States at the 2015 World Championship in Halifax, Nova Scotia, Team Shuster missed out on the playoffs when they lost a tiebreaker to Finland's Aku Kauste.

Despite finishing in second, Team Shuster earned enough points throughout the season to secure their return trip to the World Championship.

[11][12] For the 2016–17 season they added Joe Polo, a former teammate of Shuster and George, as alternate and won the 2017 National Championship.

In the semifinals, they defeated Canada's Kevin Koe, a two-time world champion, to reach the gold-medal match versus Niklas Edin's team representing Sweden.

[18] The national title would have earned Team Shuster a spot at the final Grand Slam of the season, the Champions Cup,[19] as well as the chance to represent the United States at the 2020 World Men's Curling Championship, but both events were cancelled due to the COVID-19 pandemic.

[20] Team Shuster represented the United States at the 2021 World Men's Curling Championship, which was played in a fan-less bubble in Calgary due to the ongoing COVID-19 pandemic.

[21] They played Switzerland in the playoffs, in a game which was delayed a day due to some curlers testing positive for the virus.

In the game, Switzerland, skipped by Peter de Cruz, beat the Americans to advance to the semifinals.
