Zschuppe grew up in Kirtland, Ohio. She was coached by her father in her early years. She played four seasons for Kirtland High School, setting a program record with 170 career goals and providing 39 career assists. She helped the team reach the OHSAA Division III state title game as a freshman in 2018. After another semifinal appearance, she led Kirtland to their first state championship in her junior year in 2020, scoring a hat trick in the final. She joined ECNL club Internationals SC that year and helped the under-18/19 team finish runner-up at the ECNL national finals in 2021. That performance led to her recruitment to Florida Gulf Coast. She was named United Soccer Coaches high school All-American twice, the Ohio DIII Player of the Year twice, and Ms. Soccer Ohio in 2021.
College career
Zschuppe was an immediate starter for the Florida Gulf Coast Eagles as a freshman in 2022, scoring 3 goals in 20 games and earning third-team All-Atlantic Sun (ASUN) honors. She helped the Eagles win their seventh ASUN tournament, scoring the overtime winner in the semifinals and converting a penalty in the final shootout. She led the team with 10 goals in 22 games as a sophomore in 2023, earning first-team All-ASUN honors. She helped FGCU repeat in the ASUN tournament, scoring a second-half hat trick to erase a 3–0 deficit in the final, and was named tournament MVP. In her junior year in 2024, she again led the team with 12 goals in 19 games and was again named first-team All-ASUN, helping the Eagles win the ASUN regular-season championship.
Previously a striker or winger, Zschuppe moved to attacking midfielder for her senior season in 2025. The move paid off when she scored a program record 21 goals in 17 games, winning the NCAA Division I's statistical scoring championship with 1.27 goals per game. FGCU won their second consecutive ASUN regular-season title but were upset in the ASUN tournament quarterfinals, snapping Zschuppe's ten-game scoring streak. She was named the ASUN Player of the Year and ASUN Midfielder of the Year and named third-team Best XI by TopDrawerSoccer. She finished her college career trailing only Tabby Tindell (66) for the most goals in program history (46).
