Dr. Mills "opened" David's voice when he was in his late teens, and he later became a member of the internationally acclaimed Star-Scape Singers. David was a member of the Singers for twelve years, and made his debut at Lincoln Centre in New York City. He also toured with them in Europe.

Having performed in musicals such as Oklahoma!, David's love of music has now taken him to the field of sound healing, where it combines with his passion for holistic health. Most recently, he studied with renowned sound healer, brain researcher and musician Tom Kenyon.

David has also worked in the field of audio production.
