In his hometown of Toronto, where he was constantly seen on stage playing in literally dozens of bands (guitar, keyboards, saxophones), John frequently found himself in the producer’s chair in the studio. He was driven by a fascination with recording and an increasingly obvious talent for working the boards.

His move to Los Angeles in 1989 spurred a shift into film scoring. Within a short time he was brought into a project with composer Trevor Jones, who immediately hired him to program synths and mix the score to The Last of the Mohicans. Being a mixer who can read scores and relate to musicians as a musician has kept him working in film music ever since. He has also mixed and/or programmed scores for George S. Clinton, Elia Cmiral, Andrew Gross, Jeff Danna, Mychael Danna, John Debney and others.

In 2014, John accepted an offer to become an Associate Professor at Berklee College of Music in its vaunted Music Production and Engineering Department. He is now dividing his time between teaching and mixing in Boston and producing and mixing in Los Angeles.

Recently, John has been mixing album projects for B3-Berlin, Blackie & the Rodeo Kings, JW JONES, mixing the scores to the Amazon series The Last Tycoon and the Netflix mini-series Alias Grace and the feature films The Breadwinner and The Man Who Invented Christmas for Mychael Danna & Jeff Danna. He is also creating a new Minor in Audio Post Production at Berklee College of Music.
