"David tutored my oldest son in all subjects his junior and senior year of high school. My son attended Wolcott College Prep and has a learning difference. David's patient and "no-nonsense" approach combined with just enough levity made learning fun for my son. David's approach is effective and it helped my son achieve all his academic goals. My son applied to 10 schools and was accepted to 9 of them. Included in his acceptances were Pepperdine University, Loyola Marymount, Oregon, University of San Diego, University of Arizona, and. the University of Denver. These acceptances evidence that David has the right approach to bringing out the best in his students. He also helped my younger son write papers for his Latin High School Writing class. Our family is very grateful for the work David did with our sons and we highly recommend him as a tutor for any caliber student." - Scott S.
"David tutored my daughter for the ISEE and SSAT exams for private Day Schools in New York. My daughter was pressed for time and only had a few weeks to prepare for an exam most students take a year to study. David was amazing and took his time explaining the work thoroughly. David's teaching style is so engaging, that my daughter looked forward to every session. My daughter was able to double her scores in both tests with just a few sessions with David. We were blown away by the results and are so grateful she had such a magnificent tutor. We highly recommend David as a tutor ." - Elka S.

"David and I reinforced my knowledge with the past lessons we had gone through, and I got all of my questions answered in a clear and thorough way. At the end, we created a population growth problem that was very interesting." – AP Calculus BC student, 2/27/2022 (Former Senate page, interested in a career in International Affairs, who modified the logistic model so that the carrying capacity L grew exponentially in time. He did some truly interesting mathematical modeling that might one day play a role in his future career. The model was overly optimistic about the possible effects of heavy industrialization and investment in a city like Chicago, but I was glad that he was able to construct the model and to find its analytic particular solution. -DVP)
