From 2005 to 2010, David lived in New York City, where he worked as middle- and high-school choral director at The Brearley School, a K-12 girls preparatory school on the Upper East Side of Manhattan. A busy freelancer, he was also assistant conductor of the critically-acclaimed New Amsterdam Singers and a principal conductor and founding member of C4: the Choral Composer/Conductor Collective, a collectively-run ensemble devoted to performing works written in the last twenty-five years. His love of early music led him to found and direct Guildsingers, a professional vocal ensemble specializing in 15th-century Franco-Flemish repertoire.
David received his B.Mus. summa cum laude from Washington University in Saint Louis, where he was a Mylonas Scholar in the Humanities, inducted into Phi Beta Kappa, and a finalist for the Rhodes Scholarship. He earned his M.M at the University of Wisconsin-Madison (Beverly Taylor), and received his M.M.A. and D.M.A. from the Yale University School of Music (Marguerite Brooks and Simon Carrington), where he was co-director of the University Chapel Choir and a member of the internationally-renowned Yale Schola Cantorum. He has received fellowships and grants from the Yale alumniVentures program and the National Endowment for the Humanities and, in 2015, was named guest professor at Xiamen University (China). In demand as an adjudicator and clinician, he has served in those capacities for the Lansum International Choral Competition, the Claremont College Orchestra Concert Orchestra Concerto Competition, the Oremor Choral Competition, the Chaffey Joint Union High School District Choral Festival, the Southern California Vocal Association, and many others.
