“I have known George for decades. He has a very clear and dramatic effect enabling students to think and rise to their full potential. George’s influence on so many lives has had significant impact, and I greatly admire him for doing this.”

Parent and Student Testimonials
✏️ “The first time I took an SAT math practice test, I scored a 540. I was confident in my math skills, but I still scored quite low. After learning with George, I realized that my problem solving skills were not refined. George taught me how to think. The SAT math section does not actually have any extremely difficult math. The real tough part is solving a problem efficiently and accurately. George taught me how to connect many topics of math together to do this. By the time I was ready to take the real SAT, I was scoring 800’s on the practice tests.” (800 Math SAT)
✏️ “George has been an amazing tutor who has helped me accomplish my goals in both school and the SATs. He has the unique ability to teach one concept in many ways, which is rare to find among teachers. Overall, it has been a very positive experience.”
✏️ “Math has always been an interesting topic to me; however, I never liked math class and the ways most of my teachers taught. George has been teaching me for two months so far and I feel like he has opened a whole new door of math for me. He has taught me many new topics and new ways to think. I really enjoy learning from George and I am very thankful that I was able to meet such a great teacher.”
✏️ “After trying several other tutors we had almost given up hope. We then found George and he has been amazing. Our daughter is now an A student in math and stress at home has vanished. Thank you George!”
✏️ “Dear George. You saved the day. Or rather, the semester. The few sessions you spent with our son made a world of difference – not only to his grade but to his state of mind. You showed him not only that he could grasp the concepts of his math class, but that he could enjoy the process. Thank you, thank you, thank you. We are forever grateful.”
✏️ "George’s help in my precalculus math course was outstanding. George understood that junior year is an incredibly busy year, and he wasted no time in explaining the information to me and finding the best way to convey the message. When I felt that something was too hard to understand, he would find a new way of explaining it. George always tries to make things easier to understand, but is also concerned that I perform to my best ability. George was prepared for everything that was coming in my course, and therefore I had a great advantage in the class. I’m grateful that I not only succeeded in math, but I also had a tutor that cared just as much as I did that I succeeded.”
✏️ “Our son was diagnosed with lymphoma during his freshman year and has been out of school for a year and a half. In addition to feeling sick from all of the chemo treatments, he was feeling hopeless that he would ever be able to catch up with his schoolwork. What he wanted the most was to catch up in math – Algebra II. George was the answer. For almost a year now George has been teaching him in our home for 4-6 hours a week. Not only is he catching up but he is also maintaining an A average and he will be able to enter his junior year this fall feeling completely confident in his math knowledge. We are so grateful to George for that. Although he has a long way to go catching up in all his other subjects and he still has another six months on chemo treatment, he is ready to get back to his life as a normal high school student. Couldn’t have done it without George! Thank you for your dedication to our son – mathematically and emotionally!!”
“George is a great tutor and a very nice person to talk to. I would recommend him for anyone.”
✏️ “George has worked with my children on test prep for the SAT, ACT, AP exams, and the SAT subject matter tests. My two oldest — for whom math is their worst subject — scored a 740 and a 790 on the SAT math section. My youngest just scored an 800! I, and they, attribute the high scores to their work with George. He not only helps them with the substantive skills needed for success, but also with the practical hints that come in so handy on standardized tests. He works through many practice exams and works to educate them about their particular strengths and weaknesses so that the right emphasis in studying can be made. All three of my children report that they feel that working with George has made a big difference in their school performance and test scores.”
✏️ “George is the best teacher I ever had.” (780 Math Level IIC, A in Level 1 Precalculus)
✏️ “Since I took the hardest math class at my school this year, I was nervous about my math grade. Thanks to George, on my last test I got the first 100% I’ve gotten since freshman year! My math has greatly improved since I started working with George, and for the first time I find that I am genuinely interested in math. I cannot recommend George highly enough!”
✏️ “Our daughter would have never gotten accepted to the highly selective college she now attends without George. Meaning she would have missed the opportunity to go to the school that’s turned out to be perfect for her. We thank our lucky stars for George every single day.”
✏️ “George is a super tutor that has made a significant impact on our daughter’s learning. Her progress has been beyond belief. He has worked diligently and patiently with her to fill in the gaps in her learning. She no longer memorizes formulas without knowing the why’s and how’s of problem solving. She is well grounded in the fundamentals and has gained the confidence to take on additional academic challenges. George’s math knowledge isn’t his only recipe for success, he also knows how and when to motivate a student.”
✏️ “The patience, commitment and encouragement of the instructor have helped our son bring his grades up significantly; and as his marks improved, so did his spirits and his confidence.”
✏️ “You helped our son have a dream come true, thank you.”
✏️ “I could tell, my son really liked you and already is getting huge benefits from working with you. Thank you, thank you, thank you!”
✏️ “George is a great man! In my time working with him I have learned VERY much! I believe that George’s help is of the utmost benefit for anyone who wishes to enrich themselves and to be successful in math!” (800 Math SAT)
✏️ “Who would have thought that my son would become a curve breaker! Through the years George has instilled a great store of fundamental mathematical knowledge. On this foundation our son was able to grab Calculus by the horns and completely master it.”
✏️ “George is the best math teacher I have ever had and for the first time in my life I can now say I feel confident in math. I get it! He is so organized. He challenged me to really push the limit and had confidence in me that I could achieve the goals we set together. I wasn’t to sure but with his methods, encouragement and great teaching I did it and feel great about it too. I did greats on my SATs, my math grade is an A and I now will enter the honors level. I wish I had met George earlier. Thanks George.”
✏️ “George gave me the confidence to believe that I could succeed in exams. He is a very patient teacher and is just the best at explaining difficult concepts. He makes it easy to concentrate and focus on the key parts of the course content.”
✏️ “Five years ago I was struggling in my math and science classes. I tried around with a lot of the brand name tutoring companies, but I was just not improving the way I wanted to. So, when my mother told me she had hired another tutor I felt a little reluctant. However, after a few sessions with George I could actually see results. My success in learning the material properly reflected itself in both my grades and my ability to learn new material more readily. I can’t stress enough just how different George is from other tutors. George’s ability to work with his students and figure out on an individual basis how to teach subjects is unparalleled. My junior year I managed to get fantastic scores on all my standardized tests, including a perfect 800 on the math SAT. To me, George has been a great friend and an incredible asset throughout my high school career. George makes the material accessible and I cannot recommend him enough.” (800 SAT Math, 36 ACT Math)
✏️ “George has been tutoring me for eight months. While he has a relaxed personality, he thoroughly explains all important concepts and makes sure that I full understand the topics before moving on. His knowledge is vast and I really enjoy working with him.”
✏️ “George has been working with my son since June. When I called George we had a great conversation and I explained the math issue my son was having. He understood the issues and had a solution and a game plan to attack the problem. Since working with George my son’s math comprehension and retention has improved. But more importantly, my son looks forward to working with George weekly and requires no prompting to be prepared for tutoring. He uses positive reinforcement to engage my son. Currently, George is working with my son on SAT preparation. The strategies put in place will allow my son to do well on the SAT exam.”
✏️ “For the last two years, George has done everything he could to help me in both Algebra 2 and Honors Precalculus. My grades improved significantly in a very short period of time, and were maintained throughout the school year thanks to him. He knows the material very well, he is extremely good at explaining it in simple terms, and above all, he is a very easy person to get along with. I highly recommend George as a tutor, not only for the effort and attention he put into preparing each of my lessons, but also because I know he invests that same effort and attention in every lesson he gives.”
✏️ “After reviewing the yellow insert in the newspaper, I made a note to myself: Call Perdocere? I wondered: What does Perdocere mean? After my daughter’s ACT math results, I felt it was important to take action, so yes I did call Perdocere and spoke with George. After listening to our story, George met with my daughter to begin immediate math tutoring. We had limited time, six months, to accomplish a lot of learning in order to achieve a more successful math test score. Equally important, my daughter was to improve on her math for success when at college. George is a brilliant and enthusiastic teacher. He shared his plan with us and we quickly moved ahead. He had my daughter take both the SAT and ACT practice tests to see which would be best for her. He watched her to see how she worked. He prevailed upon our busy schedule for intense tutoring. George expects a lot from his student, but he gives much in return. For my daughter, she learned that math from him, and he instilled confidence. For me, he kept me in the loop and patiently worked with our schedule. At the six month point my daughter retook the test with George’s best wishes (and his calculator as her calculator shut down days before the test), and she exceeded her goal. Perdocere means to instruct thoroughly, Perdocere is George! Thank you!”
✏️ “We give high praise and appreciation to Dr. George for the effort and care he has put into our son’s math and science tutoring! Our 8th grade son just received his SSAT score report and is in the 99% of the Estimated National Percentile! Also, just as wonderful, is the noticeable increase in our son’s self-esteem and confidence! Dr. George has shown that his consistent and kind approach to teaching can lead to a strong sense of self! Thank you so much Dr. George!”
✏️ “George made a huge difference in how our son approached math problem solving, as well as in how to take the SAT. George quickly identified fundamental mathematic deficiencies and provided the education required so that these principles can now be applied in any setting, not just in taking the SAT. We look forward to working with George again next year. Thanks George from all of us!!!”
✏️ “Throughout the SAT math class, George has made all the questions that are considered hard seem so easy. He has also shown me different ways to come up with an answer for each question. This has caused my math grades to improve!”
✏️ “Our middle school son started to have difficulties in mathematics. After working with him, George was able to assess and pinpoint his areas of difficulty. In addition, George had the patience and teaching strategies that worked with our son. Now he enjoys the challenge of math and feels so much better about his abilities. His grades have gone from a C+ to a B+, and now A’s.”
✏️ “George has been the best investment we could have made for our son. He has been tutoring him for over two years now and our son has been in honors math ever since. He and George are now in the process of SAT ‘training’, if you will. We just know that his scores will be nothing but impressive. Thank you, George.”
✏️ “George has been an excellent tutor and mentor to me. When I started with him I was failing my geometry class. Within only a couple months he helped my grade go up by three grade letters. Thanks to him I will be finishing the years with a solid grade. Not only has he helped me academically but he has also made me more confident in my classes and work. At my hardest struggle, George took his time to spend many extra hours with me. He teachers like no other teacher and is able to make strong connections with his students while teaching the best techniques and strategies to solving problems.”
✏️ “Having George help me kept a smile on my face. I was never left hanging before a big test.”
✏️ “Math SAT 800, 36 on the ACT Math, and 99% in Math Honors Pre-Calculus. In the time that we have worked with George that was the result. I do not believe anybody could have achieved better results. George, however, makes it look easy. What else can you say.”
✏️ “George is hands down the best tutor we have ever encountered. He understands that students cannot excel in math unless their knowledge is built on a solid foundation. In tutoring my daughter, he returned to basics, discovering areas of weakness and explaining misunderstood concepts. A comment that my daughter made in passing, “I can ask George any question about math, and he can answer so that I can understand.” While he is conservative in making promises about outcomes, he committed himself 110% to ensure as successful an outcome for my daughter as possible. Our first goal was to achieve strong performance on the math SAT, where he approached the subject matter in a methodical, knowledgeable way, she scored a 780 on her first math SAT. With that successful experience under our belt, we then wanted to ensure strong classroom performance for the fourth quarter of her junior year. My daughter was receiving B+’s in her honors pre-calculus class (and averaging B’s on her tests and quizzes), but the subject matter became increasingly more challenging, and she was faltering in her ability to grasp concepts, particularly with respect to the topic of probability. George worked week in and week out to review the various chapters with my daughter, preparing her for tests, encouraging her after a difficult test. She received a B+ for her fourth quarter work, which I believe would have been significantly lower without George’s help. In order for my daughter to achieve an A- for the year, she needed a 95% on her final exam. George worked tirelessly to help her achieve this goal, but again was cautious in guaranteeing any results. My daughter and I were thrilled to see her report card a month after her final, with an A marked clearly for her final exam! We look forward to George helping us negotiate BC calculus as well as the Math Subject II test in the fall!”
✏️ “George is a wonderful example of a professional instructor for mathematics and science. The quality of instruction administered in a calm, patient, and open manner reflects his true concern for the student. The dialog that exists between teacher and student is superb, as the knowledge that is sought and shared establishes itself. We are glad that academia has produced such a top notch instructor for our son.”
✏️ “As parents, we all know how different our children are – and this certainly translates to learning styles. George has had to adapt to three very different types of learners over that last seven or eight years. He has successfully navigated one child through a string of 800s… brought another near that coveted goal, thus ensuring his place at the college of that child’s choice (thank goodness!!)… and now has the unenviable task of guiding our daughter through the shoals of high school mathematics and preparation for the SAT. All three of our children have enjoyed working with George; he has related to each one on a very personal level and he has adjusted his teaching style to match how they learn. He is always encouraging and has instilled in all of them the ability to ask questions and explore the whys and wherefores rather than just the answers. At the same time, however, George sets the bar high for each one of them and pushes them to achieve. Not only have they and will they be accountable to Mom and Dad – they are also accountable to George – and they seem to be more concerned about the latter rather than the former (which is fine with us). George has an extraordinary gift for teaching and for instilling a love of learning in his students. He is insistent that fundamentals be strong and he works those so that his students are equipped for higher tasks. On child ended up majoring in math in college and is now doing sophisticated quantitative analysis in an investment firm; another is doing a wonderful job navigating econometrics. We can only hope that our last one can achieve this success. With George on our side we think that this can be achieved. We heartily recommend George to all.”
✏️ “This year our son attended the Perdocere Math SAT Prep Course. George’s clear, well-presented explanations and thorough review of the SAT Math was very helpful. We finally found someone with a high-level math knowledge base and also with the unique and most important quality – the skill of teaching in a manner that is understandable. George has helped our son gain knowledge, skill and confidence.”
✏️ “Working with George has improved my math skills immeasurably. I was able to achieve a near perfect score on my Math SAT as a result of George’s dedication, patience, and skill in our tutoring sessions. He made sure I not only understood the concepts but had a deep knowledge of them. I also worked on my school work with George and felt that our work together put me well ahead of my fellow students.” (790 SAT Math)
✏️ “George tutored my daughter in math this summer. He clearly has knowledge and patience to tutor with confidence. He took pride in making sure my daughter understood the material covered, without tests and grades, only with positive feedback and enthusiasm. Thank you.”
✏️ “I met George in February of my junior year. Earlier in my junior year and sophomore spring, I had been bounced between countless math tutors who seemed uninterested in actually changing the way I learn and comprehend math on different levels, which is a necessary transition from my school math course work to solving problems on the ACT. A few had deemed me incapable of ever truly raising my math IQ and relied heavily on strategy to get me through standardized testing problems. Yet with George, everything changed. He studied the way I learned and took tests, and synthesized the information I gleaned from each of our sessions. He then broke down my entire bank of knowledge in the realm of mathematics and we started from the bottom, building our way up. As each new brick was laid in the foundation, my confidence grew and my ability to take control of the ACT in a way that worked for me was apparent. I no longer fear ACT test day, new units in Pre-calculus or a problem that seems overwhelmingly difficult based on its exterior. George became my math savior and I can not thank him enough.”
✏️ “Every time I see George with my son, I feel very happy and blessed knowing that he is in good hands. My wish is not just for my son to raise the points or grades but also to learn what “study” truly means through Math so that he can apply the concepts and skills across the fields in his lifetime. George is a teacher and mentor who can make my wish come true.”
✏️ “Before working with George, I thought of math as a drudgery. The subject required a lot of work and study, but it seemed to me that no matter how hard I applied myself, I could not affect a change in my grade. Math was a chore and an ugly spot on my report card. After being taught by George, however, that all changed. George takes the time to explain the mechanics behind a formula, never allowing memorization where there is understanding to be had. Under George’s tutelage, I began to see the beauty of mathematics, and as my interest in the subject grew, I found myself considering it less a boring necessity, but a more rewarding challenge. George’s teaching has turned my opinion of math completely on its head, and also yielded pleasant results during the final exam. Although my term grades before meeting George were not fantastic, I was able to score highly enough on my final exam to bring my overall math grade up to an A-. Without George’s careful guidance, this certainly would not have been possible. I cannot recommend his services highly enough – under George, not only my grades, but also my outlook on math changed for the better.”
✏️ “All three of my children are tutored by George in math, chemistry, and physics. Not only is George capable of tackling all three different subject areas, he is able to relate to the very different learning styles of each child.”
✏️ “George has helped my daughter realize that she really could understand math. Her improved test scores inspired her to work harder, not just in math, but also in all her classes. Her confidence and ambition both grew as she realized that she could master a difficult topic. George has the gifts of a good translator and teacher, he listens extremely well and then uses words and descriptions that can help students decipher difficult concepts. George’s approach to learning, studying, and preparing are completely transferable across many subjects.”
✏️ “George has a very nice personality and is very smart. He has a nice way of conveying information to hold my son’s attention. George has been very helpful to my son, bringing his grades to a passing A and building his confidence in math.”
✏️ “I am very impressed and happy with George as a tutor for my daughter. With his extensive knowledge, he can instruct her in both math and science, both for the classroom and SAT prep. I think he is very patient as he works with the student and is able to quickly discover how best to work with them.”
✏️ “Whenever I am concerned teachers may have assigned material that is too difficult, my daughter says “Don’t worry, I have the best tutor ever.” With George, you couldn’t ask for more. Brilliant and charismatic as a math tutor, and with a special winning personality, George is gifted in explaining math to teenagers.”
✏️ “The children never complain that George is boring or off topic or that he is a waste of their time, and they would if they thought that. Almost any other teacher or tutor did elicit those comments sooner or later from the same children. They tell us that even though George makes them work hard, the effort is worthwhile and that they are being exposed to something uniquely valuable and not duplicative of school work.”
✏️ “George quickly and accurately assessed our son’s needs, then put together lesson plans, exercises and study guides geared to address his specific needs. He just came home with his first A.”
✏️ “With George SAT preparation is not just about the test. It’s also about confidence, George is capable of getting a great effort from the student and perfection becomes an attainable goal. When the student aims for 800 in the SAT with George even a score of 780 becomes a disappointment. George has been a godsend in that respect.” (800 SAT Math)
✏️ “George was a great teacher to have while I was preparing for the SAT. He really took the time to get to know what my strengths and weaknesses were, how I worked under test conditions, how I approached problems, etc. Just after one session he knew how to guide me and helped me set realistic but challenging goals. George made sure that I had clear and basic foundations for solving problems and then worked with me step by step until everything was clear and I was confident about how to handle similar problems. His teaching not only helped me through the SAT but has also followed through into my everyday school work. His enthusiasm and dedication is really meaningful and one thing for sure is that George knows how to teach.” (280 point SAT math increase)
