Keith was born and raised in Tarrytown, New York, where he attended Sleepy Hollow High School. He was a 1987 graduate of the New York University Tisch School of the Arts. While attending NYU, he also received theatrical training at Circle-in-the-Square and Playwright's Horizons theater schools.
His first professional job was in a production of Jean Cocteau's The Infernal Machine at the Jean Cocteau Repertory in lower Manhattan. Most recently, Keith appeared as Tybalt in Romeo and Juliet and Octavius in Julius Caesar -- both at the Shakespeare Theatre. Other stage credits include productions of Othello, The Beaux Stratagem, Cymbeline, Hamlet, and Coriolanus for The New Jersey Shakespeare Festival, The Actors Theatre of Louisville, The Huntington Theatre Company and the North Shore Music Theatre.
Further endeavors include teaching acting at Youth Theatre Interactions, Inc., and a performing arts program for children in South Yonkers, New York. In the capacity of both actor and director, he has worked for the past several seasons with The Playwright's Theatre of New Jersey in its Special Needs Program, teaching playwriting and performing the plays of youthful offenders within the New Jersey correctional system.
Keith enjoys cycling, swimming and fencing, and has a passion for all things Shakespearean.
