Born and raised in Vancouver, British Columbia, Samantha is a graduate of the acclaimed Circle In The Square Theatre School in New York City. She moved to London forming Suspect Package Theatre Co with fellow Canadian actor Trevor White ( Downton Abbey/ Industry), where their productions received critical success. An Evening Standard review for "Problem Child": 'It is impossible to maintain a detached reaction to Suspect Package Company's provocative production, largely due to the impressive Ms. Coughlan's sympathetically psychotic performance'. She made her West End debut in the Olivier and Tony award winning "Death of a Salesman" as "Miss Forsyth" opposite Brian Dennehy and Clare Higgins. Theatrically she has further worked at The Old Vic under Kevin Spacey, with Josh Hartnett and Adam Godley on "Rain Man", directed by Terry Johnson, as well as a cover for both Keira Knightly and Elizabeth Moss on the "The Children's Hour" directed by Ian Rickson, and on the groundbreaking 5 star production of "A View From The Bridge" directed by Ivo Van Hove, amongst many other productions. In 2012 she was nominated for a Best Actress OFFIE for her work in Tennessee Williams, "Vieux Carre" at The Kings Head/ Charing Cross Theatres. Samantha is also a successful VoiceOver artist working across the boards in radio drama, commercials, audio-films, documentaries and was the US voice of Nike Training Club from 2011 until 2017.
