Born and raised in the Bronx, and spent most of his formative years hanging out in New York City, Kirk Acevedo, who is of Puerto Rican descent, received his BFA from SUNY Purchase and founded a theater company called The Rorschach Group. After guest-starring on several television shows like New York Undercover (1994) and Law & Order (1990), he landed his best-known role as Alvarez, a morose and violent prisoner struggling for redemption on HBO's notoriously gritty Oz (1997). Though he was nominated for a Cable Ace award and an ALMA award for his work on Oz (1997), it was Acevedo's role as Pvt. Tella in The Thin Red Line (1998) that won him an ALMA.
