"David is a born pedagogue in every way. His grasp of fundamentals, his ability to communicate and connect with students and his deep understanding of all things violin, are truly inspiring, even (especially) to his colleagues. Watching him teach, analyze and get straight to a young person’s needs is a clinic unto itself. He has an uncanny ability to instantly recognize students’ strengths, build on them and then calmly organize even the most poorly trained pupil, getting them to improve very quickly with just a few suggestions. He is not prone to long discourses-he simply builds up the student and gives them confidence to correct their flaws. His knowledge of the repertoire is superb and he is equally at home teaching every genre and period of music presented to him."---Andrés Cárdenes
