Keir Gilchrist is a rising British-Canadian film and television actor most known for portraying Marshall Gregson on the Showtime original series United States of Tara
, a dramedy about a working mom (played by Toni Collette
) afflicted with dissociative identity disorder and the unique challenges it poses to the family. Born in London, England, Gilchrist was raised in Boston, Massachusetts and New York City. When he was ten, his family finally settled in Toronto, Canada, the place he has called home when away from work in Los Angeles, California.

It was mostly due to the encouragement of his acting coach that he decided to make acting a profession. Gilchrist was only ten years of age when he made his television debut as the son of police chief Jim Stockwell on Queer as Folk
. His first feature film appearance was in a Canadian comedy-drama The Right Way

as Josh, the smart 13-year-old son of Alison McKellar (Erinn Hayes
) who forms an unusual bond with Glen Abbott (Rob Corddry
), their neighbor 20 years his senior. In his guest appearance on The Listener
, Keir played a teen suspected of being involved in a series of store burglaries. In 2008, he was flew in for an audition in Los Angeles by the producers of United States of Tara
