My Story

A passion for detail

After graduating from UCSD’s Revelle College as a Music Technology Major in 1999, I moved to Los Angeles to pursue a career in Audio Post Production. I quickly found my niche working in commercials for huge brands such as Nike, Microsoft, Target, Starbucks and Old Spice to name a few. To date I estimate that I have mixed over 500 commercials.

In addition to commercials, I also have a strong passion for film and television. In 2015 I joined the Motion Picture Editor’s Guild aka the Union with the long term goal of becoming a supervising sound editor and re-recording mixer for major-studio feature films. I am an associate member of the Cinema Audio Society, and Motion Picture Sound Editors.

Please check out some of my favorite Sound Design and Mix projects, and I hope to work with you soon!
