Born in the Bronx, he started out in the theater in Neil Simon’s “Brighton Beach Memoirs” after attending the High School of Music and Art. His other Broadway roles came in “The Green Bird,” directed by Julie Taymor, “Awake and Sing!.” “Golden Boy,” “Rocky” and most recently, the revival of “Six Degrees of Separation.”
