Prior to joining the Raiders, Grenis graduated from Appalachian State, where she was a four-year member of the field hockey program. Grenis was a two-time Mid-American Conference (MAC) regular-season champion in 2023 and 2024.

Grenis appeared in 44 games, making 41 starts, and earned the starting role in goal during her junior and senior seasons. The Syracuse native totaled 165 saves, posted a .671 save percentage and accumulated a 24-15 record in goal, while recording 10 career shutouts.

Academically, Grenis earned a bachelor's degree in environmental science and a master's degree in geography, both from Appalachian State. Grenis was a four-time recipient of the NFHCA Division I Scholar Distinction Award, a two-time selection to the MAC All-Academic Team (2024, 2025) and a CSC Division I Academic All-District selection. She was also selected as Appalachian State's 1A FAR Academic Excellence Award recipient from the Sun Belt Conference.
