"Parents of my students have been universally impressed with David's aptitude for helping their children develop a thorough understanding of complicated material. He does a great job making sure that students understand all aspects of a concept [...] He is always on time and prepared, and his patience, kindness, and visible belief in students' capability have been transformative in encouraging even reluctant students to dedicate themselves to realizing their potential."
