“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 is fun. Before I started working with him I always hated going to math but not anymore. I enjoy math. I don’t want it to end. He is doing an amazing job getting me up to par with my grade. He is the best math teacher I have ever had and the sooner you start working with him the better. If you put in the time he will be able to catch you up and get you in front of your whole school. If you don’t work with him it’s your loss.”
✏️ “George works miracles! When I first started with George, I took a practice SAT and sadly got a 550. George explained that he was going to rebuild my math knowledge and rewire how I looked at math problems. Over the course of the summer and fall, George continued to work with me and with his careful instruction, guidance, and support I was able to get a 780 on the real SAT. George taught me to think differently and to approach math problems in creative ways. George pushed me to be the best student I could be, but never pushed me in a way that was counterproductive. Though I was not confident at the start, George’s never ending encouragement and faith in me allowed me to finally recognize my full potential in the SAT and in my math classes at school. I can’t thank George enough!” (780 Math SAT)
✏️ “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.”
✏️ “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.”
✏️ “You have set the ‘gold standard’ that I don’t think anyone else can approach.”
✏️ “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 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 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, 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)
✏️ “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!”
✏️ “George has tutored my daughter in Pre-Calculus and Math SAT prep for the past year. George has very impressive credentials, but even more impressive is the math rapport he has with my daughter. Clearly, George understands math at a depth and breadth that few of us do. But his ability to teach it and be a successful tutor is really what impresses me the most. He is a natural teacher. He can see when a student isn’t “getting it” and he can explain a concept in a variety of different ways instead of merely repeating the same explanation again and again. And finally, George truly seems to love his job. He appears to be genuinely happy when my daughter accomplishes her goals or nails down a difficult concept. My daughter feels her time with George is always productive as he’s always prepared for their session.”
✏️ “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.”
✏️ “Having George help me kept a smile on my face. I was never left hanging before a big test.”
✏️ “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?” ”
✏️ “You helped our son have a dream come true, thank you.”
✏️ “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’s influence was not only on math but his success comes from the universality of his was of thinking. George has become a good friend and has really changed our boy’s life for the better.”
✏️ “George is a fun guy who knows his stuff. He is enjoyable to work with and the results are astounding.”
✏️ “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.”
✏️ “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.”
✏️ “Working with George has changed my life for the best. When I first started High School, I was still overcoming many challenges involving my health – which had been affecting my grades as well as what classes I had to take. Once I met George tough, I knew he was different than the countless other tutors that had come and gone through my life. George was able to get me to heights I’d never even believed I could reach. The passion that he has for mathematics and his endless dedication to his students is visibly seen every time he’s doing a lesson. Not only has George been a fantastic tutor but he has also been a great friend. He’s given me important input to major decisions I’ve had to make in my life whether it’s what college or even what classes I should take. There’s nobody I can credit more when it comes to the straight A’s in math classes I’ve taken these past four years and the 710 & 750 I received on the SAT and SAT Math IIC than him. I would have never believed back then that George would’ve had the impact that he has now on my life. Thanks for everything, George.”
✏️ “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.”
✏️ “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.”
✏️ “He takes the time to understand the individual needs of our child, and goes the extra mile to make sure our son has all the material needed to be successful. He builds a clear picture for success with forward thinking and planning, makes sure the child is at ease, and provides great feedback on each lesson.”
✏️ “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!”
✏️ “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 brought my grade from 63 to 100. Enough said.” (Honors Algebra II Student)
✏️ “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!”
✏️ “Thank you so much for all you do for our son, and for us!”
✏️ “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 has helped me to understand algebra better than my teachers at school ever could!”
✏️ “George is a good teacher because – he makes me think the math out, he is always prepared for what I need to learn, thinks of problems to illustrate a math concept on the spot, drills me on what I do not know, makes me tell him how I arrived at the answer, understands me and how I learn, focuses and encourages me, talks to me.”
✏️ “George is like no teacher I’ve ever had. He takes what looks like a hard Math SAT problem and simplifies it so everyone can understand.”
✏️ “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!’ ”
✏️ “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.”
✏️ “With SAT’s looming, I hired George to access and fill in the gaps in my son’s math knowledge. My son scored a 550 on his first practice SAT with George, so there were plenty of areas that needed attention! George came up with a comprehensive plan to rebuild my son’s math knowledge from the ground up. George taught my son to look at math through a completely different lens, which enabled him to think creatively as opposed to mechanically when he approached math problems. This strong foundation coupled with a creative approach to problem solving resulted in a 780 on the SAT. George was professional, methodical, and thoughtful during each session, and knew how to motivate and inspire my son. Although the work was hard at times, my son was always happy and grateful to be working with such a brilliant and kind teacher. I only wish all of my son’s math teachers could be as exceptionally qualified and compassionate as George!” (780 SAT Math)
✏️ “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 is not an ordinary math teacher. Not only did my son receive phenomenal math tutoring, but George also boosted his confidence. I’d overhear George encouraging my son, ‘Let’s look at the problem carefully, it’s easy…’ By upping my son’s self esteem, George was able to improve his score. George also built up my son’s stamina by having him take full length practice tests so he’d be prepared for the actual SAT.”
✏️ “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.”
✏️ “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!”
✏️ “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.”
✏️ “I don’t know how we came this far without George. There has been a tremendous improvement in our son’s work. He has the A’s to prove it. George is truly a gem.”
✏️ “Initially we brought to George tutor our daughter in AP physics. He ended up tutoring her in both Physics and Pre-Calculus. He also provided help in preparing for SAT and ACT exams. We were very pleased by his dedication as a teacher. He goes above and beyond the average tutor by following up on exam results and checking in the night before to make sure she was ready or to answer any last minute questions. My daughter truly believes she would not have made it through those classes without George’s help.”
✏️ “George taught me the difference between wisdom and knowledge, and George is by far the most experienced and intelligent teacher I have had the pleasure of working with.” (800 Math SAT, 800 SAT Math IIC, 36 ACT)
✏️ “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)
✏️ “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.”
✏️ “Our daughter was transferred to Dover-Sherborn High School as a sophomore last year. We thought she needed some math guidance before taking the ACT/SAT, and discovered Perdocere Math Tutoring while searching online. George turned out to be the best discovery we made. His brilliance, patience, and structured tutoring style made our daughter feel at ease with the fundamental concepts of math. Needless to say, George’s guidance was reflected by an outstanding score last month. For math tutoring, George should be your first and final contact.”
✏️ “SAT, PreCalculus, Mid Year Exams – not something you want to think about, especially not all three and trying to cram all of them in less than five months. Before George I can say that to do all this and do well would be impossible; I had no confidence in myself. Finding George and getting tutored by him has been one of the best decisions my family made as he turned something that seemed hopeless to something achievable. As a student, I know that schools have a set curriculum where their goal is to teach everything they need in one school year, but sadly in doing so they rush; they teach their students to solve things a certain way with the no explanation of why or how they got there. So before George I was basically a robot taught to memorize everything with the explanation of ‘because that’s just what you do’. George, on the other hand taught me the basics, teaching how and why things worked, what is really going on in a formula or an equation. He taught me each and every bits and pieces of math to help understand why things are the way they are. I now understand math more that I have ever did. Not only that but after really understanding something he goes above that to where he introduces more complex things to keep the mind going, building on the strong foundation that he has created. This showed its work on the SAT and in school. The SAT (Math) is all about understanding and thinking skills; George helped me to improve my thinking skills and understand math problems. At the same time he help me to easily do things in school with his teaching; things that seemed difficult before are now much easier to where now I can see how it works, identifying the building blocks of math to help me solve the equation. George is the best tutor and teacher I have ever had in my life; he has a superior understanding of math and he used it to help me get high scores on the SAT and high grades in school. He has proven to me that he loves his job, to help and see his students succeed, using every bit of time productively, encouraging his students that they can succeed with his teachings and hard work. George has done so much to help me succeed in school and on the SAT. I could not have asked for a better tutor. Now it is time for SAT II, where I am certain that George will help me achieve a high score.”
✏️ “Before I met George, math was just another subject to painfully struggle through in order to achieve passable results. Once he and I began working together, it opened my mind to the possibilities that I could have with the joy of math. As my ACT math tutor, George made me realize how important a good work ethic, fun spirit, and a willingness to learn can create a love for something that I never thought I would’ve enjoyed. Now I can say that I am confident and happy in doing math not only for the sake of learning something new everyday, but also because George showed me how to take pride in something that I can do.”
✏️ “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.”
