The rising actor began his training at small theater companies in New York City as well as the Professional Performing Arts school in Manhattan, where he trained for seven years until graduating from their high school in 2020. Back in 2015, Sumpter landed a role in the Musical Runaways which was performed at City Centre, as well as the Delacorte theater in 2018.
