Mission Statement

To me, composing is a balance of free creativity mixed with an analytical approach of studying the narrative the music will be supporting. From the instrumentation, to the harmony, rhythm, tempo, I take all aspects of the music into consideration to compose tunes that authentically tell a story.

As a proud Canadian I have been honoured to compose music for many Canadian stories as I strongly feel our voices should be heard and celebrated.

I am always looking to work with other musicians, creators and performers! Please contact me if you are interested in collaborating on your project; whether is be a theatre or film score, concert band commission, choral arrangement, recording... I enjoy working in various mediums and genres of music!
