“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
✏️ “As an extraordinary tutor for classroom math in both middle school and high school, we have now asked George to prepare our daughter for math on the college SAT. We have absolute confidence in George to help our daughter achieve her highest possible SAT math score.”
✏️ “George recreates the art of tutoring: he is like a muse who inspires learning as an art.”
✏️ “George has been an invaluable asset to me. Ever since I began seeing George five years ago he has been there to help me through whatever material I was struggling with. Whether is was my eighth grade algebra or my senior year AP calculus George has been able to not only teach me the material but to have me understand it as well. George helped me to get the 800 on the Math SAT and was even able to teach me in biology as well. After trying other tutors I can say without any reservation that George is the best out there. George presents the material in a way that is easily accessible and learnable, making sure that each student is able to learn the material in his/her own way. For my part George has both my thanks and respect for all that he has done. I can’t recommend his services enough and urge you, if you want to see real results George is the one to use.”
✏️ “Perdocere Math Tutoring with Dr. George was the best decision we ever made for our son. George has not only given our son the knowledge and understanding of math, but the confidence to master it. He has given him the skills and confidence he needs to truly be a success. We can thank him for not only the math skills learned but also his advice in SAT management and preparedness and in interview techniques. We give Dr. George a perfect score!”
✏️ “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.”
✏️ “This is exactly what we have discovered in George – To Teach or Instruct Thoroughly. George not only has read our son’s Advanced Algebra book, he has wrapped himself around it. He teaches with enthusiasm and a deep concern for our son. He genuinely cares that our son not only understands the many different concepts but also makes sure that our son is able to effectively apply them. Our son has 125 new problems every week and George makes sure our son fully understands each and every one. Our son’s grade has improved from a B- to an A- and we expect this trend to continue along with his growing mathematical confidence. Our son smiles broadly at the end of every session. George is the MVP of the academic playing field! Thank you George.”
✏️ “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)
✏️ “We can’t say enough about how good a teacher George has been throughout the years. We feel that our children are well grounded in fundamentals and have the confidence to take on any academic challenge in the future. George is devoted to his craft and a truly unique academic tutor.”
✏️ “George was a wonderful tutor for my daughter’s Math SAT prep. George has a complete understanding of the Math SAT test. He is also skilled in teaching high school students this information. We were thrilled with the results! A very satisfied mom.” (730 SAT 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.”
✏️ “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 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!”
✏️ “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.”
✏️ “George has been tutoring our son for over a year and this year he is the top student in his honors precalculus math class. He’s a more confident student and is willing to help others in his class so they may be successful. That helps to reinforce what he is learning, as well. This year, he has been studying for the ACT and SAT with George and we anticipate good outcomes!”
✏️ “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.”
✏️ “Our son is a very good student but has found that he does not process information as quickly as it’s given in school. George has been tutoring our son for only eight months and already he has seen great improvement. In addition to increasing his math grade to an A, George has been able to increase our son’s confidence in all subjects.”
✏️ “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!”
✏️ “George has been a helpful, effective tutor whom I would recommend to most anyone. He quickly shows you everything there is to know about SAT math and installs it into your memory. Furthermore he is a nice guy who genuinely wants you to improve.”
✏️ “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!”
✏️ “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)
✏️ “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 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 has made such a big difference for our child – academically and personally.”
✏️ “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 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.”
✏️ “When I began my sessions with George, I was very apprehensive. I didn’t enjoy math and spending two extra hours outside of school was not something that I looked forward to. As the weeks went on, my confidence in my abilities skyrocketed. George quickly defined my problems, and made a long lasting impression on the work I now do. Not only did my scores dramatically increase but so did my school work. I now approach problems differently and find math to be more enjoyable. George is a wonderful teacher and I cannot explain how much he changed my approach to math. If I have any advice, it would be to listen to everything he says. He knows what he is talking about and the next time I walk into a mathematical minefield I know there will be a trap in the dusty corners that I can conquer. Thanks for everything George!”
✏️ “George is a great SAT Math tutor. His thorough knowledge of every part of the test definitely helped me to understand how to take the test in a better and more efficient manner. We tackled each problem as it came and not only solved it but broke down each component of the question so that we could easily tackle a harder version of the same problem down the road. In just three sessions of preparation with George my test scores increases by sixty points and branched into the 700 range. I believe that George’s attention to every detail of the test is what sets him apart from other tutors I tried and is what allowed me to do so well.”
✏️ “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 is a pro. He has years of experience tutoring students lacking self confidence in math. He covers all the foundations, enabling the students to succeed. George has tutored my son for two years. In that time, he has grown into a good student who loves math and gets the grades to prove it. His success has been empowering and translated across other subjects. Besides being and excelled teacher, George is a genuinely nice man. My son and I are big fans.”
✏️ “I understand my math now, I can go to class knowing the material on the test and am confident on what I need to know to get a good grade, I have gone from failing in math to being an A student.”
✏️ “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 is a brilliant mathematician who has the rare ability to convey that knowledge to our teenagers. He is an effective communicator who teaches with patience, determination and perseverance. George understands that confidence is the most important ingredient for learning and empowers our children to believe in themselves.”
✏️ “I’m proud of my accomplishments since he has worked with me.”
✏️ “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.”
✏️ “Thank you for your excellent help during our daughter’s absence from school. She returned not missing a beat in Trig and Chemistry. Not only that, your joy in teaching the material and encouragement further increased her interest in both subjects and boosted her confidence. We hope you will be able to continue working with her – it is such a pleasure to watch a child bloom academically!”
✏️ “George is the best math tutor imaginable.”
✏️ “George set an amazing foundation for my AP Physics course, when he taught me some basic calculus, which allowed me to understand how all the formulas interconnected, rather than simply memorizing them.” (AP score 5)
✏️ “We just keep coming back for more! George has been working with at least one of our children for the past five years. He has firmly grounded them in mathematics and physics and has given them the confidence to handle any problem set that is assigned. Perfect or nearly-prefect SAT and SAT-II scores have also come the children’s way during this time – and George can truly take credit for readying them for these standardized tests. He knows that strength in fundamentals and hard work are the most important variables in the success equation. George is an educator first and foremost. He explains concepts in a clear and concise manner and has a way of consistently reinforcing these concepts. He pushes his students to achieve… but always in an extremely supportive manner. George does what is necessary to ensure that his students understand what is being taught. He wants all of his students to succeed – and is truly vested in their success. In sum, we can’t say enough good things about George… now if only we could clone George for the SAT critical reading.”
✏️ “I’m in honors math. However, I couldn’t handle Algebra-II as well as Honors Geometry. So my grade began to slip so my parents called George. It was the best decision. George knows everything about math and he was able to guide me through the daunting path of Algebra-II and Trigonometry. He made everything less intimidating, and within no time, my grade was back up. George is definitely going to be my tutor next year.”
✏️ “George has been more than a math tutor for me. He has not only taught me everything I need to know to succeed in math class and on the SAT, he has also become a best friend during the process.”
✏️ “Frustrated by the lack of tangible Math achievement in my children, who are good students, through their middle and early high school years and with one facing the SATs in the spring I needed to act fast… I decided to tutor them. After trying a few tutors where the fit was never quite right I stumbled on to Perdocere and from day one my problem was solved! George understood completely what I wanted: to improve their math school work, prepare for their SATs, but also to make sure that they knew MATH. I asked George to make sure that all his math tutoring would stick; I didn’t want them to ‘just learn it for the test’. His success is tangible. They have great grades and success with the SAT. One of them said to me ‘Mom I learned more in four hours with George than I did all year in my math class!’ ”
✏️ “We are ecstatic about the progress George has made with our daughter’s math scores. He has instilled possibility when she knew only defeat. The experience of success in math has given her tremendous confidence. Higher math had been out of her reach, but now it is easily grasped. George’s knowledge is boundless, not only in math, but also in knowing how and when to motivate psychologically and emotionally. He is always prepared and upbeat and he keeps each session moving enthusiastically. Our hope was that George would just give our daughter the ‘jump start’ she needed, but in fact, he has become a part of our lives for years.”
✏️ “This year, I am taking the most rigorous math course my school has to offer, AP Calculus BC. BC calc is extremely fast paced because of the AP test in May. Some of the topics are only covered for a fraction of a class; however, with George’s help, I am a month or two in front of the class. Because of the two month lead, George is able to show me more advanced topics that will never be covered in BC calc. The way that George teaches calculus incorporates everything that was previously learned in calc while still covering a lot of material extremely thoroughly. In class, I have done well on all of my tests. George has allowed me to obtain an understanding of calculus which seems impossible to get from the class alone. I am very thankful that I have George guiding me through BC calc.”
✏️ “Working with George has been great and I really look at my classes in school in a different way. I know that I can rely on George to go that extra mile to make sure I really understand what I’m learning, and that makes school much more manageable.”
✏️ “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!”
✏️ “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.”
✏️ “When most people think of a ‘tutor’ they think of an individual that helps with a particular subject area, usually through studying or practice. When I think of George I find the standard definitions of ‘tutor’ no longer apply. Although George is great at ‘traditional’ tutoring he has a skill set that enables him to do so much more. His ability to teach material in a way that is easily comprehensible makes learning material unbelievably easy. I started with George in the 8th grade when my math grades were not so great. He took my grades in my 8th grade algebra course and turned C’s into A’s. Five years later I graduated high school with an 800 in my math SAT, a 790 in my math SAT IIC, and an A- in AP Calculus BC, the most difficult math class ever offered by my high school. George truly is the best, from science, math, and in my personal case, computer programming. George has the esoteric knowledge and raw intellect necessary to come through on his business name and `instruct thoroughly’.”
✏️ “George enabled me to get an 800 on the math SAT and, for most parents, that may be all they need in a tutor. However, George isn’t just an effective tutor, he actually cares about the student. When I first started with George math was my least favorite subject, mainly because I just didn’t ‘get it.’ However, now, math is my strongest subject and I adore the class. George allowed me to not just ‘get by’ in my class, but to understand the material, and, through understanding excel. I can’t recommend George enough on both a professional and personal level.” (800 SAT Math, 36 ACT Math)
✏️ “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.”
✏️ “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!”
