I can't express enough praise for Dr. H! A true expert in his field, very passionate about his subject as well as warm and patient person. He has an amazing ability to explain the most difficult concepts and make it very accessible. My son has a great admiration and respect for Dr. H. After only a couple tutoring sessions with Dr. H I noticed a big improvement in my sons grades. Now he aces every test. Dr. H is a very inspiring and motivating teacher, I see a drastic improvement in my son's working habits in general.

Mark tutored my son in Calculus for a quarter. Only wish I had found him sooner. Very easy to interact with as a parent and student. Always encouraging of my son and gave him the confidence to do well and improve his grade. Extremely reliable in terms of promptness and preparation. Flexible when we asked him to be. You'll be happy if you give Mark a whirl. We recommend him highly.

Mark has years of experience in the Physics and Math fields. He makes formulas very understandable. My daughter was able to recall formulas that she learned three years ago with Marks help. Thanks Mark I know with your help she will do well on her SAT subject exams.

Mark has been tutoring my son in Calculus and Physics II. He is very patient and inspiring. Mark has been able to focus on my son's strengths and opportunities for improvement and encourage him to improve in the areas that need help. My son, an 11th grader, is much more confident about math and science and always welcomes his time with Mark. Mark has encouraged my so much that he actually spent several hours on extra credit physics problems and then helped a 12th grader with her homework. He did all of this with a smile on his face. I highly recommend Mark.
