Greg's professional pursuits began at DePaul University in Chicago,
Illinois where he studied with pianist Larry Novak and
composer/arranger Cliff Colnot. At the same time he had the good
fortune of working with the city's top-call studio vocalists and
performers, with whom he got his start composing and producing in the
jazz, R&B and soul genres. After moving to Los Angeles in 2000, Greg
began working with veteran film composer Patrick Williams, and produced
and arranged a new album for vocalist and former American Idol finalist
Justin Guarini. Recently Greg joined with Williams and composer David
Levy to form a full-service music production company, Threshold
Music.
