In recent years Mark was commonly recognized as “The Sleeman Guy” in those wonderful beer commercials.

Most recently, he has worked as a resident artist and dramaturge for Terra Bruce Productions based in St. John’s, Newfoundland. He truly has the gift of holding captive and engaging an audience with his performances. He attributes much of his success in front of the camera to his many years as a stage performer. Mark has also received training from some of the best in the industry, both from Canada and abroad. He has numerous TV appearances and film credits to his name including Sisters, Murdoch Mysteries, Republic of Doyle, Son of a Critch, Pixels, Pompeii, and Love and Savagery, to name a few. He also has completed a number of voice-over projects.

His roots in theatre give him an impactful presence in both film and in live performance. In addition to being a founding member of The Irish Stage Company (Stones in His Pockets), he has written and produced two one-man live performance productions, Is This Love?, and most recently the autobiographical show, Raised on Songs and Stories.
