Alagia was raised in Brooklyn, New York. She received her B.A. in theater, graduating with honors from SUNY Oswego. She is a Jill-of-all-theater-trades, fulfilling roles such as actress, director, stage manager, prop artisan, and African-American hair designer for shows such as August Wilson’s The Piano Lesson, Grease, A Raisin in the Sun, Titus Andronicus, August Wilson’s Gem of the Ocean, and I'm Black When I'm Singing, I'm Blue When I Ain't. Alagia practices theater as an ancestral duty of storytelling. She plans to further this transformative art into a master’s in drama therapy to deepen her community work within the African Diaspora and underserved communities. Community outreach with a strong focus on youth development and engagement is her passion.
