“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
✏️ “When George takes on a student, for him it is not just a job, for him it is a commitment which he honors spectacularly. A commitment to help you do well in school and also a commitment to actually learn the subject matter.”
✏️ “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.”
✏️ “George is a tutor extraordinaire. He is a born teacher who genuinely enjoys the kids he teaches and the work he does. He inspires his students to do their best and is able to establish a rapport with each of them. George has tutored my three teens for several years, responding to each one’s different abilities. He has helped them in all kinds of math, chemistry, physics, ACT, SAT – you name it, George can handle it! George has given each one a very positive learning experience, leading to greater self-confidence and enthusiasm for the subject matter. George encourages each child to take responsibility for his or her own learning. George has a wonderful ability to present concepts in a highly organized manner. All three of my kids report that George’s explanations are better than what they received at school and help them to really understand the concept as opposed to a mechanical application of ‘the rule’. None of the three ever grumbled about working with George. If they are having difficulty with a topic, they don’t panic because they know George will explain it and help them understand the issues. They all three see George as a friend as well as a tutor, as do I. When my two oldest are now home from college, they love to visit with George and bring him up to date on their academic progress.”
✏️ “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!”
✏️ “Our daughter has always struggled with math, especially on standardized tests. Always a good student and hard working, she was always disappointed with her test scores. By working with George, she has grown in her understanding and grasp of the subject. My wife and I are encouraged to see her renewed energetic interest in achieving in math which for too long has been so frustrating and intimidating for her. George, thanks for all your help.”
✏️ “As someone who usually finds math difficult and boring, I was relieved when I understood how easily George can get me to grasp concepts I couldn’t fathom on my own. In a span or roughly two and a half months, I have had results that were 150 points higher than my first SAT math score. George’s brilliance and enthusiasm made it easy for me to take my work seriously, and overcome my frustration and difficulty with SAT math. Nobody has the aptitude George has to boost math scores through efficient techniques for problem solving and test taking, or can rival his knowledge of mathematics.”
✏️ “Ever since I began my sessions with George, I have significantly improved my mathematical skills and have consistently been able to maintain high test scores. George has restructured my foundation and constantly solidifies key concepts, which help me to take each problem step-by-step and achieve the correct answer while truly learning the material. George not only helps to get the correct answer but also goes far beyond what is asked and works out multiple solutions to the simplest and most difficult problems. George is able to break down problems into manageable pieces unlike any other math teacher I have ever had. I commend George for his knowledge on the subject. I know with George’s help and positive attitude, I am confident that I will do well. Without George both my algebra and chemistry skills would be nothing like they are today. Thanks George and I can’t wait for another successful year!”
✏️ “Not only has George quickly and effectively helped my daughter to significantly raise her ACT math scores but he has boosted her confidence ten fold!”
✏️ “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.”
✏️ “George has been tutoring me since the eighth grade. Ever since we started working together, my grades have increased dramatically in math class. I like the approach George takes to tutoring. Unlike the teachers at school, George will teach you thoroughly, no matter how complicated the task. In eighth grade I was barely passing my math class. George has shown me that I am capable of getting A’s; it just depends on how well you’re taught the material. The following year I got a 93% on my Algebra I final. George’s charismatic attitude is a huge part of what makes him so special. Math class in school is generally like going to the dentist. It isn’t remotely pleasant, but you’ve got to do it. George somehow makes the experience an absolute pleasure. I look forward to our meetings. I’m confident that George has the intelligence, experience, and the overall talent to teach most anyone with excellent results. Believe it or not, not everyone is up to the task of teaching math. I can say whole-heartedly that I believe George is, and then some.”
✏️ “George started late in the year tutoring our son, in a very short time his grades were up. His scores on the SAT and AP exams were exceptional. However what is more important is that George is coaching him on how to study and not only tutoring him in a subject. He is helping him choose his courses, as well as guiding him through his high school years. The look on both their eyes while studying is one of pure joy. George is an exceptional tutor as well as a dear friend.”
✏️ “We first looked for a tutor when it became clear that our son did not understand the material in his honors pre-calculus class and was moving from a passing grade to a failing grade as the material became more difficult. We asked George to work with our son. He first worked to stop the immediate problem by working with him on a quiz by quiz basis. As this crisis diminished, he has devised a longer-range plan to bring our son up to the point where he can achieve on his own. George has a rare skill of understanding the material and being able to communicate it in a way that our son could understand. Thanks to George, our son has renewed his confidence and improved his grades enough that he is now on a course to respectfully pass his honors pre-calculus course.”
✏️ “My senior year brought with it an abundance of math challenges. I had decided to enroll in BC Calculus, as well as take the Math II SAT2. I never considered myself to be particularly good at math, so I was very worried about how my various math undertakings would pan out – but, under George’s tutelage, I ended up doing better than I could have ever expected. Often investing extra time into lessons, George Patiently taught me enough about precalculus and calculus to raise my average SAT2 by more than 180 points and nudge my math grade to an A. George takes the time to explain the underpinnings of each theorem, never resorting to memorization when there is understanding to be had. Whenever I brought my confusions to George, he could explain with perfect clarity what had gone wrong in my calculations. Two years ago, I never would have envisioned myself having my current relationship with math – one where I can look forward to new challenges rather than dread tests and quizzes. Without George’s unparalleled skill as a teacher, I would never have improved in math to the point that I have. As a student, I cannot recommend George highly enough. More than achieve tangible results in terms of grades and numbers, I have developed an entirely new attitude towards mathematics thanks to George.”
✏️ “I’ve always struggled with pre-calculus and calculus. My teachers never taught the theory behind the problems, or how it was connected to the big picture. George makes it his mission to make sure you thoroughly understand the concepts of the subject.” (college calculus student)
✏️ “After the first couple of math tests at the beginning of my sophomore year of high school, I knew I needed help. After just a couple of sessions with George I immediately became a standout in the classroom, consistently on the verge of a perfect test. George rebuilt the foundation of my mathematical skills, allowing me to see the ‘big’ picture and to intertwine new ideas with old concepts. His ability to aid me in understanding the undercurrents of what my teacher was lecturing on in school allowed me to excel in the classroom. I have had George as a tutor for three years and he has inspired a sense of appreciation in the workings of Mathematics that I am now considering pursuing the subject as a major in college.”
✏️ “George did an excellent job working with our daughter over the past year. He built her confidence and knowledge base so she could execute complex math problems under time pressure. We believe that one of George’s key strengths is his ability to work with strong students in advanced classes to achieve top performance. In addition, our daughter had fun working with George. We will use him in the future.”
✏️ “George tutored our daughter for almost a year. He is a one of a kind teacher because he is so good as what he does. Our daughter said that George was able to teach her math concepts in such a way that she really understood the topics. Prior to George she was able to get through Algebra and Geometry courses with good grades but without understanding the material. George is very dedicated, very enthusiastic and really knows how to teach for understanding. He is also patient and positive and was good for my daughter’s confidence. She liked him very much which is always important too. I am not a fan of today ‘s highly pressured academic rat race, and I believe children are suffering mentally and physically. However, having a good tutor can really help certain students to succeed rather than just stumble through.” (U.S. exchange student, online tutoring, Viterbo, Italy)
✏️ “In a word, George is wonderful! Highly experienced in all branches of mathematics, he also is an exceptionally nice person who cares about his students. Along with solving the problems du jour, he has imparted life lessons about setting goals, working hard, and planning for the future. After working with George for six years, my son will graduate high school with an A in Honors Math and head off to be a math major in college. Back in seventh grade, I wasn’t sure how this was all going to play out. I owe a huge thanks to George for all he’s done for my son. I am so glad I made the call.”
✏️ “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 is a truly amazing teacher. Not only is he incredible capable and knowledgeable but also sincere and caring. He knows how to captivate a student’s focus and how to motivate them. There is nobody better than George!”
✏️ “Thank you so much for all you do for our son, and for us!”
✏️ “I am very happy to recommend your services to any family that wishes to prepare their children above and beyond what is found in the secondary schools curriculum. Our son who had a declining grade eight in middle school transitioned to Walpole High School and achieved honor roll status his freshman year. His continued Math and Science success is continuing now into his sophomore year and none of this would have been possible without your help. I can’t thank you enough for not only your Math and Study Skills help but more importantly your teaching the importance of life skills to our son. It has been said that ‘If you give a man a fish you give him a meal, however if you teach a man to fish you feed him for life’.”
✏️ “Following a couple of years with disappointing math teachers, my son was struggling in his Algebra 2 course – and then the pandemic hit, and distance learning compounded his problems. At this point we reached out to George. George took the time to work back through the older material to build up a strong foundation for future success. The first few months were triage; even so, we noticed improvements in performance almost immediately. In addition to laying a strong mathematical foundation, George has done a great job teaching my son solid study habits and test-taking strategies. My son is comfortable with the material and confident that he will perform well on his tests. I am certain that my son is now on a trajectory that will guarantee success in math through the end of high school and beyond.”
✏️ “George has been an inspiration to our son! He now has the confidence that he can actually understand and be successful in math.”
✏️ “I can always rely on George to help me understand a particularly challenging concept in math.”
✏️ “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.”
✏️ “George’s stand-out credentials and many years of experience made him our first choice when we searched for a math tutor for our high school-aged grandson. As it turns out, George’s singular talents go far beyond these qualifications. He quickly established a genuine rapport with our grandson and made a thorough assessment of his academic strengths and weaknesses. In this context, he went back and rebuilt our grandson’s foundations in math, filling in gaps that would no doubt have become increasingly problematic in the coming years. He improved our grandson’s attitude toward learning and noticeably grew his confidence. He showed him what and how to study and how to apply his new knowledge effectively. George’s mentorship has surpassed our expectations and has proven to be an invaluable asset for our grandson. We are very pleased to have found him and recommend him highly.”
✏️ “George has instructed our son and now our daughter. We have found that George tailors his teachings to meet our children’s individual needs and not just the ‘text book’. George covers everything and then he covers it again making sure they understand thoroughly. It is with great confidence and pleasure that we recommend George to be the very best available!”
✏️ “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.”
✏️ “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.”
✏️ “George’s math skills and patient manner have increased my son’s confidence and competency in his own math skills. He is able to explain complicated math concepts in simple terms while making the process enjoyable. George’s enthusiasm for math is contagious and helps ensure his students to be equally enthusiastic.”
✏️ “Thanks again for everything you have done for the boys – you really have a gift!!”
✏️ “George has been working with our son for more than a year now. We can’t say enough for George’s abilities to teach – whether it be physics, mathematics or SAT prep, George ensures that our son has a comprehensive understanding of the materials. He challenges him to think through problems and apply concepts. George also has a way of making learning and academic achievement something that our son is proud of. He has instilled in him a level of confidence in his academic abilities that would not have existed absent George. Anyone wanting a truly dedicated teacher and genuinely nice guy to work with their son or daughter should always look to George first.”
✏️ “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, over the past few months, we have been amazed at the progress you have made with our daughter. While the improvement in her ‘trial run’ SAT scores has been significant, of equal note has been the change in the way she now approaches math problems: she thinks differently! Your ability to explain the processes behind the formulae, and the way that you teach to each student’s strengths, is a thing of beauty… For a 17 year old to stay focused on math over and entire summer is a testament to your ability to engage someone’s imagination and intellect. I am grateful for all of the encouragement and focus you have provided. And, while I look forward to much improved success in our daughter’s upcoming SAT scores as a direct outcome of your work, I also appreciate the confidence you have helped her build over the summer. She is clearly far more prepared for the tests ahead than she was in early June. My only regret? We didn’t do this sooner.”
✏️ “Although I’ve only been with George for a short while, the most important thing I have discovered about him is that his teaching style is highly effective. Not only does he teach you how to do something, he teaches you why it is done that way. He is able to show you how basic concepts can be used to solve highly complex problems. Now, I am able to see the building blocks of each individual problem, and, from there, I am able to find the solution. He is totally approachable and will help you with anything. I know on countless occasions he has also given me advice that I find applicable to my physics homework. He truly does instruct his students very thoroughly, and if you are unsure of something, he will go over it as many times as you need. Because of him, I feel thoroughly prepared to take my SAT exam.” (700 SAT Math)
✏️ “George, many, many thanks for all your hard work with our son. You were the only outside tutor we used that truly put your heart and soul into his success – from identifying weak areas to intensively reinforcing all areas. His results speak volumes about how you opened up his understanding of math (and helped jack his score up to a very competitive level). Personally, your commitment and steadfast resolve towards his SAT results was remarkable.” (740 SAT Math)
✏️ “Our student’s first week of school vacation has been exciting to say the least! He’s already six chapters into his AP Chemistry book for next fall and because he respects Dr. George very much; he’s enthusiastic about hitting the books. His “A’s” in both Honors Geometry and Honors Chemistry came in the mail yesterday and the smile on his face was priceless! Thank you George!”
✏️ “George has been more than just a tutor. He is a friend and a mentor for both our children. Perfect SAT and ACT scores were just the beginning. George is still with them in college. His methods and teaching skills are more than what we imagined. The sooner a child starts with George the better his foundations are made solid, and the confidence the student acquires with his help goes beyond math to encompass all the curriculum.” (800 SAT, 36 ACT)
✏️ “Even though my strength has always been in writing and English, I am now an A student in math and science as well because of George.”
✏️ “Along with information, George offers support, encouragement and understanding. He communicates complex ideas in a very comprehensible way.”
✏️ “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.”
✏️ “We knew our son was brighter than his grades were showing. George did wonders, going back to basics and making sure he really understood the underlying concepts for both math and chemistry. His grades have improved, his confidence is back, and he recently hit the 700 mark on his math SAT. Now, if only we could send George to college with him...”
✏️ “Over the last two years, week after week, month after month, George sits patiently with our son doing what George does best: teaching thoroughly. Being able to communicate with a teenager so he understands math inside and out is a gift, George has that gift.”
✏️ “My son has been tutored by George for the last three years. During that time he has gone from a struggling student to one who feels a confident mastery of the subject. George has built up his understanding by patiently explaining the basic foundation of math as well as adding enrichment when my son was ready. He now loves math and we owe it all to George!”
✏️ “I used to hate math and everything to do with it. But now that I’ve been working with George and I am ahead in my work, I absolutely love math now. I can’t even tell you the satisfaction I get when I know all the math in class the first time the teacher tells us. Also, my grades couldn’t be better right now, and it is all due to George”
✏️ “What would our schools be like is we could witness George’s way of teaching there? Quality, it works!”
✏️ “George has been tutoring our son for four years, and we are extremely pleased with the results. George has taught our son the way he needs to be taught to, he is positive, thorough and focused. Our son has a confidence in his abilities he could’ve only imagined before. George not only teaches, he mentors and advises, he truly cares about his students and their accomplishments. We highly recommend George, he will not disappoint!”
✏️ “We felt like we struck gold shortly after George began to tutor our son toward the end of his junior year. The impact was almost immediate. He skill level went from a fail to pass in a few sessions. George has an expertise in communicating math and science surpassed by no one. He was able to identify and fill in the gaps in our sons math education in two-hour per week sessions when regular classes and after school failed. Our sons precalculus and calculus teachers were unable to communicate the subject matter in a way that our son could understand. Our son proclaimed that George was the best math teacher he ever had in his entire high school career. He had somebody who could explain abstract concepts in a way he could understand. George prepared our son for the SAT exam and continued tutoring our son during his senior year in high school for advanced math. Honors precalculus and calculus are hard enough subjects for anybody to grasp or master, but they are especially difficult when you have a learning disability. We have no reservation in giving George our highest recommendation.”
✏️ “The best tutor we have ever had, and the nicest!”
