Josh Casaubon was born in Brunswick, Maine and raised in New Hampshire and Massachusetts. After a stint at the University of Maine, he served four years in the United States Army as an infantryman, stationed in Hawaii. While there, he received numerous awards and was selected for the Special Forces, but chose instead to begin a career as a writer. He was honorably discharged and moved to New York City in the summer of 2001. While attending New School University, he immersed himself in the diverse cultures of the West Village and found himself wandering into small theaters, sneaking into "Inside the Actors Studio" sessions on 12th Street and philosophizing with local bohemians until sunrise. He soon discovered that he had a natural talent for acting. It became a passion, and then an obsession. He has since performed in dozens of television shows, plays and films and has never looked back, though he spends a large amount of his free time writing. He and his wife moved to Los Angeles in 2011.
