In 2014, Muise and her team of Lyndsay Allen, Sarah Evans and Sara Gartner Frey won the provincial club championship and represented Alberta at the 2014 Travelers Curling Club Championship. There they finished with a 3–3 round robin record, not enough to advance to the playoffs. The team also won The Good Times Bonspiel that season, defeating Jessica Hanson in the final 9–1.^[8] Two years later, Muise returned with her same team to the 2016 Travelers Curling Club Championship where her team found success. After finishing the round robin first in their pool with a 5–1 record, the team won their semifinal matchup against Ontario 7–1 to qualify for the final. After a tight final match against Manitoba's Tracy Andries, Muise's rink would allow Manitoba to take four in the last end for an 8–5 victory.^[9] Despite the loss, the Muise rink returned once more to the 2018 Travelers Curling Club Championship and qualified for the playoffs with a 5–1 record.^[10] After wins over Manitoba and the Northwest Territories in the quarterfinal and semifinal matches, Muise would win her first national championship with a 7–3 win over Nova Scotia's Michelle Williams.^[11]
