Since founding the a cappella production company diovoce in 2000, his clients have appeared on numerous "best-of" compilations, including over 35 appearances on the BOCA, CAMO, Voices Only, and 'Sing' series. Dave's work has received dozens of CARA nods, both as a performer and while "behind the glass".

Dave is the founder of the Alliance for A Cappella Initiatives, and creator of the hit SoJam A Cappella Festival, as well as the internationally acclaimed 'Sing' vocal compilation CD.

Dave has performed with numerous ensembles, directed the UNC Clef Hangers, and has toured the globe and recorded with vocal tonic, transit, and Almost Recess. His work has afforded him the opportunity to work with many talented recording artists, including Ben Folds, Brendan James, and Anoop Desai.

In 2006 Dave partnered with several fellow producers to form VocalSource, which represents the most comprehensive network of vocal music studios in the world.

In 2008 Dave merged the AACI with CASA, and is excited to join the CASA Board of Directors as the Director of Events, managing SoJam, the East Coast A Cappella Summit, and a growing network of CASA festivals and events around the world.
