“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
✏️ “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 by far the best teacher I’ve ever had! The way he teaches and presents the material is unlike anything I’ve come across. I’m not sure why I’ve never witnessed this way of teaching before, because it clearly works! The math really does become clear with George at the reins. When I look at any sort of math problem, I can truly say I understand all the pieces and how they interact. My way of thinking about math has always been a way that has irritated and frustrated my teachers because I don’t always catch on as fast as the other students would. George is able to pick up on this and teach the math at any angle to suite my learning style. I am highly confident that he will do the same for you!”
✏️ “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 been working with my son for the school year and his Math grade has moved up by a full grade. More importantly, he now has a solid understanding of Algebra as he moves on to High School. My son’s confidence level has soared too. George knows what is important and he makes the experience fun as well.”
✏️ “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 started working with our teen last year after being recommended (highly) from a friend. We were impressed immediately – he connected with our son and tuned into his style of learning from the very first session. Not only has our son improved in math, but the PSAT/SAT prep work he is doing now is sure to reap benefits during this coming year. We just wish we had found George years ago!” (700 SAT Math)
✏️ “George re-defines the definition of tutor. We have never met anyone with his credentials, mastery of the subject and infinite sense of caring and can-do attitude. The stress level as it relates to school work has gone way down in our home since he began tutoring our daughter. We only wish we had met him years sooner.”
✏️ “George is a good guy. A+ tutor. Great results, my son scored a 730!”
✏️ “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.”
✏️ “Our middle school son has a broader, deeper understanding of math concepts since working with George. He no longer memorizes formulas without knowing the why’s and how’s of problem solving. George can teach tough math concepts in an understandable way that translates into learning!! The success our son feels in mastering the math is a great boost to his self esteem. He just got an A+ for the year in eighth grade algebra.”
✏️ “When I first met George, he gave me a diagnostic practice SAT math, and I scored a 530 on the SAT. Now, I can hit 800’s with time to spare. George has taught me new math topics, but he has mainly taught me how to think. He has shown me that each math problem can relate to the other, so you can solve each problems in a myriad of ways. We have sat down together and searched for new ways to solve the most difficult problems. It is almost like George unlocked something in my brain that now allows me to see all of the different solutions to each problem. Once I see all the possibilities, I can choose the most efficient and safe solution which now allows me to score 800’s.”
✏️ "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.”
✏️ “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)
✏️ “Thanks to George I not only feel more confident in math, but I also feel like I am receiving a strong education from someone who is dedicated to helping people learn. Every lesson is based on what I need, and he never disappoints. His approach to math is both fun and engaging. He helps me get the results I want without substituting memorization for learning.”
✏️ “We are absolutely thrilled with what George has done with our son. He has instilled a sense of confidence, made him realize that he can excel academically and allowed him to set his sights on things that he never thought he could achieve. George is incredibly knowledgeable, extremely approachable and a fantastic teacher. He has gone out of his way to make sure that our son is always prepared for his next challenge. George will be part of our family’s academic life for years to come!!”
✏️ “We have had many tutors in the past and George by comparison is extraordinary. George’s weekly sessions helped my high school boys achieve never before A’s in their math classes. My husband and I were so impressed with his intelligence, dedication and patience. These qualities allowed my boys to truly understand SAT test taking and math strategies. We highly recommend George!”
✏️ “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 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.”
✏️ “George has been tutoring our son for over two years now, we are very pleased with the results. Our son has a real appreciation for the method in which George teaches, and is confident in his own abilities now to understand and comprehend challenging concepts. With George the lesson is always positive, focused and thoroughly understood. Besides being such a wonderful tutor, mentor, and motivator, George has encouraged our son to excel in other pursuits as well, always looking toward the future. We highly recommend George!”
✏️ “We would heap praises, but facts speak better. With a ‘C’ in 8th grade math, and teachers happy with ‘the C’, which translates to just passing 8th grade MCAS at the cut-off grade, we looked to George to teach our child. The weekly two-hour session is productive and fun for our child! We would never have imagined our child sitting for two hours on High School Algebra – but it happens every week – only with George. George finds a way to teach and convey concepts in math – overcoming our child’s learning disabilities. Our child brought home a B+ in Algebra, and in one Algebra quiz, got the first time ever 100%. Our child has gained confidence which beats the frustration and ‘I hate math’ during 8th grade.”
✏️ “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)
✏️ “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 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.”
✏️ “The best tutor we have ever had, and the nicest!”
✏️ “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!”
✏️ “George was flexible and accommodating when my daughter and I found ourselves overscheduled one month before three scheduled SAT-2 examinations. He organized a study program, identified the appropriate tools, and worked out a mutually acceptable schedule on short notice. His thorough understanding of the information and the test process coupled with his kind and cheerful personal style was very effective. The outcomes met our very high expectations, and we look forward to working with him in the future.”
✏️ “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.”
✏️ “Thank you so much for all you do for our son, and for us!”
✏️ “George is the real deal. Not only does he have a stellar educational background and a wealth of experience, but he has the tutorial skills to impart various math concepts and a real gift for connecting with students. My son has happily worked with George for five years; during that time, he consistently has brought home A’s. Simply put, George is the best there is.”
✏️ “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.”
✏️ “George is very patient and explains everything in language that I can understand. He always encourages me and praises my accomplishments. I know that my SAT scores will be the best I am capable of. George has really made a difference!”
✏️ “I missed a year and a half of school and George has been very helpful in getting me caught up in math.”
✏️ “George is a wonderful tutor that has made a significant impact on my daughters learning. He discovered her weaknesses and has worked tirelessly with her to fill in the gaps in her learning and prepare her for the SAT. He cares deeply about his students and communicates weekly with me on her progress. George is like no other!!”
✏️ “I wish we had found George sooner! He has done a wonderful job of not only teaching the current year’s math, but also of going back and filling in the missing pieces of our son’s mathematical foundation. He has helped him in the sciences, and as we move into SATs, I expect to see his positive influence there as well. Our son in a more confident student because of George. However, I think George’s greatest strength may be sensing what learning style fits our son and being able to adapt on a given day to what he needs, both emotionally and scholastically.”
✏️ “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, 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.”
✏️ “I recently told a professional colleague about the most amazing man, Dr. George. She confessed that her son was bored in math and I shared that our son had admitted the exact same sentiment and that he too didn’t want to approach his math teacher because he would simply receive more homework instead of the progressive math education he was looking for. I told her that Dr. George has come to our house for three years, and every single time he tutors our son he has the same kind, upbeat, prepared approach without fail and that Dr. George is our best resource for MCAS, SAT and test prep hands down. He shows up more than prepared and always with the same sincerity every single time, simply to teach our son in the best way our student can learn. Simply put, we can’t do without Perdocere and our son’s grades are the proof!”
✏️ “George hands down takes the prize for the best overall math tutor. He brought my math SAT score up 220 points while maintaining my honor role status. George is an authentic man who truly cares about his students.”
✏️ “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.”
✏️ “Along with information, George offers support, encouragement and understanding. He communicates complex ideas in a very comprehensible way.”
✏️ “What would our schools be like is we could witness George’s way of teaching there? Quality, it works!”
✏️ “George, you are perpetually a star! Thanks so much for all your help with our son. We are so very appreciative.”
✏️ “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)
✏️ “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.”
✏️ “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!”
✏️ “Believe it. It’s true. Before George started tutoring our daughter, I read every single one of the testimonials on this website. It was clear the students and families were overwhelmingly pleased, but could he teach our child? It took mere minutes before I heard our daughter say, "Oh I get it! That’s easy" At that very moment, two things happened. I quietly breathed a sigh of relief because I knew we had found the perfect tutor, and our daughter began to believe in herself. The big question in our house a few months ago was “What are we going to do about math?” Now we’re looking far ahead and wondering to ourselves, “What will she do with math?” ”
✏️ “In my junior year in high school I was taking some challenging courses, courses which on my own I would have had trouble handling in combination with SATs and AP exams. However, George helped me manage not only my classes but also my standardized tests. I ended up with solid grades in my math and science classes as well as an 800 in the math portion of the SAT and a 780 in the SAT IIC for math. Without George’s tireless enthusiasm and unstoppable will to help me I don’t know how well I would have done.”
✏️ “I’ve been a student of George’s now for four years going on five. I tried other tutors but no one really does it quite as well as George. He does his best to help the student and to ensure their good performance. One night, before the SAT George stayed with me for roughly six hours to ensure that I got my 800 on the math portion of the SAT. Overall George is the best tutor I’ve had thus far, and if you are looking for honest results George is the way to go.”
✏️ “Thanks again for everything you have done for the boys – you really have a gift!!”
✏️ “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.”
