Sheehan attended St Paul's school in Portlaoise. Unsure of whether acting was a sustainable career choice, he studied film and television at Galway-Mayo Institute of Technology. He missed several months of the course to film Summer of the Flying Saucer, and then failed his first year examinations, and decided not to attempt the repeats. Afterward, he spent some time performing stand-up comedy throughout Ireland.
