After graduating high school, Clifford was recruited to the University of Alberta Pandas curling team where she played third on the junior team led by Marks. In their first season together, the team, with Paige Papley and Jamie Scott on the front end, won the Alberta junior championship. This qualified them for the 2020 Canadian Junior Curling Championships where they finished where they finished 6–4 through the round robin and championship pools, tying them for third.

Later that season, Clifford joined the Pandas varisty team as their alternate at the 2020 U Sports/Curling Canada University Curling Championships. After going 6–1 in the round robin, the team won both their semifinal and gold medal matches to secure the title.

Because of a change in dates for the Canadian Junior championships during the 2020–21 season, Curling Canada selected the athletes that would represent Canada at the 2021 World Junior Curling Championships. Clifford was chosen for this team, alongside teammates Marks, Scott and Brianna Cullen. However, the world championship was cancelled due to the COVID-19 pandemic.

Women's Aged out of juniors, Clifford continued competing with Marks and Papley as they picked up Selena Sturmay as their new skip. This team saw moderate success together, reaching the final of the Avonair Alberta Curling Series event and the semifinals of the Red Deer Curling Classic and Thistle ACS event.

They also had a strong showing in their first tour event, the 2023 Saville Shootout, defeating the likes of Kerri Einarson and Gim Eun-ji en route to a semifinal finish.

With all their playoff appearances throughout the fall, the team entered the 2026 Alberta Women's Curling Championship as the number one seeds and qualified for the playoffs through the A side, defeating second seed Selena Sturmay. They then beat Sturmay again in the 1 vs. 2 game to qualify for the final where they'd meet Sturmay for a third time. After giving up a steal of two in the third end, the team trailed throughout the rest of the game, ultimately losing 9–5 and finishing second.
