Jeff has been tutoring my son for the past year and a half, both in-person and online. Last school year, with Jeff’s help, my son achieved excellent results in Grade 11 subjects (Functions, Physics, Biology, and Chemistry). I was so impressed with Jeff’s professionalism, teaching strategies, and pleasant manner that it was an easy decision to continue having him tutor my son during Grade 12 (currently for Biology and Chemistry). As a parent, I feel blessed to have found Jeff! My son’s level of stress has gone down, as he is able to ask Jeff to clarify any difficult concepts. Jeff is well prepared with detailed lessons and practice work on every chapter. He helps with homework and assignments and does it all with patience and care. My son has improved not only his grades (i.e., 94 in Gr. 11 Bio, and 88 in Gr. 11 Chemistry), but also his work habits. I truly believe, that having Jeff tutor my son has been one of the best things I could have done for my son’s future and for my own sanity. Thank you Jeff for changing lives one student at the time!
