Born and raised in Nepean, Ontario, Canada, Adam began his multifaceted career in entertainment when he was twelve on the 80s Nickelodeon cult comedy, You Can't Do That on Television (1979) At sixteen, he graduated to the writing department and co-wrote thirty episodes of the show with producer/creator Roger Damon Price. He attended Sir Robert Borden H.S. and was a member of the National Champion High School Improv Team (along with his friend, fellow S.R.B. alum, Sandra Oh).

Adam then attended Ryerson University's film program and won the 'Norman Jewison Filmmaker's Award' for his graduating short, "Token for your Thoughts", which also won a 'Gold Plaque Award' at the Chicago Intercom Festival. From there, Adam began to straddle both passions as an actor and filmmaker - directing commercials, music videos and shorts, while touring and performing with one of the most popular Canadian comedy troupes at the time, The Komic Kazes. This experience helped him land his first film role in the feature, Kids in the Hall: Brain Candy (1996).

In 2010, he completed his first feature documentary film, Dancing in the Flames (2009), about the life of the renowned Jungian analyst, author and revered wisdom keeper, Marion Woodman.
