I started with a Film and Television degree from the University of Alabama. In 1990 I did “Fried Green Tomatoes”. Since then I have been on a fantastic journey of the film with many wonderful people. I have been very fortunate to have worked with some great visual directors such as Joe Johnson (October Sky, Hidalgo) Denis Villeneuve (Prisoners) Edgar Wright (Baby Driver) and Damien Chazelle (First Man). One thing I have found is that great visual storytellers know how important sound is to the final film.

She first became “aware” of audio while studying Arranging and Composition at Berklee in Boston. While recording a term project in what was then a little 2 track studio, she became fascinated with the world of sound…. this led her from musician, to live sound, Record Engineering and finally into Post Mixing. She considers herself very lucky to be working within this talented community of people who have continually inspired her to refine my craft and grow my love of mixing.
