Antonia was born and raised in Atlanta, GA, though she attended John S. Davidson Fine Arts Magnet School in Augusta, GA, for middle and high school, which is where she developed her love of acting. The Davidson Fine Arts' Facebook page recently gave Antonia a shout-out in honour of her new show, writing, "DFA Drama alum Antonia Gentry stars in new Netflix series Ginny & Georgia airing this February! Yayyyyyyy Toni!"
