A 6-6 forward, Donovan Grant played two seasons at Campbell HS in Smyrna, GA, averaging 15.2 points per game and graduated in 2019, according to Maxpreps.com. A season with the Atlanta based Skills Factory followed in 2019-20, where he was signed that summer to play for Division III New York University. Unfortunately, NYU cancelled its 2020-21 season due to COVID-19, and he never played there.

Grant returned to Atlanta and played in the NBA Academy circuit, walking on at Oregon State two years later in the fall of 2022. Grant did not see any action as a freshman during an 11-21 season at OSU, and signed with Georgetown after entering the transfer portal in April 2023.

Playing in the first three games of the 2023-24 season, Grant left the Hoyas at the conclusion of the fall 2023 semester.
