In addition to voice acting, he has appeared in live-action roles, including guest spots on the television series Wayward Pines, Supergirl, and Family Law. He is active in his professional community, serving on the executive board of the British Columbia branch of the Canadian actors' union, UBCP/ACTRA, and speaking at industry events.
