“Cinema is a medium that you see… but feel through your ears.”
Gary Rydstrom (seven-times Oscar winner)
My journey in sound began over three decades ago, driven by a fascination with what can’t be seen but deeply moves us.
As a Drama-Comedy sound editor, each project is a new conversation — between picture and emotion, between silence and meaning.
I’m here to make that dialogue unforgettable.
