And after several Regional (including The Cleveland Playhouse) and Off Broadway successes (La Mama, The Irish Repertory Theatre, Primary Stages, Manhattan Theatre Club, etc,) and landing the same agent as Jack Nicholson he moved WEST to Los Angeles where actors go to die. John travels between Los Angeles, New York, Toronto and Vancouver. His life resembles a circus at times as he travels with his son Odin and dog Charlie.
John has just completed the sold out hit LADIES AND GENTS in the toilets of Central Park, NYC.

He created the role of Declan in Ladies Night – The Live Full Monty – where he stripped to hundreds of screaming women that all looked like his mother.
He joined the sci-fi world by recurring as Niam on the TV Series Startgate Atlantis – which shoots in Vancouver – where he plays an Ancient Replicator. He originated the role of GODZILLA in Crow’s production of the most successful play ever in Japan - GODZILLA by Yasuhiko Ohashi.
