“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
✏️ “George’s results have been spectacular in terms of overall grasp of subjects and preparation for specific exams. He is the cause of one or more of our children getting perfect or nearly perfect scores on SAT or AP tests where, in some instances, the effort was there but, prior to George, not much interest or aptitude a specific subject. He visibly changes good students into superlative students.”
✏️ “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.”
✏️ “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 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.”
✏️ “George has not just taught me, but he re-wired my brain in a way that allows me to comprehend subjects I haven’t gone over with him. He has given me the tools to understand any math or science problem out there.”
✏️ “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.”
✏️ “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.”
✏️ “I’m proud of my accomplishments since he has worked with me.”
✏️ “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.”
✏️ “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’.”
✏️ “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.”
✏️ “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.”
✏️ “George is a miraculous Math tutor. At the end of December I called George and told him my predicament, that my son was doing his mid-terms in a few weeks time and that he needed immediate Math tutoring. George tutored him five times before his mid-terms and he did very well. I’m grateful to George for coming to our assistance at such short notice. In addition to doing so well in his mid-terms my son has gained much more self-esteem in himself as George taught him how to approach doing Math homework and prepare for quizzes and tests.”
✏️ "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.”
✏️ “Math has always been an interesting topic to me; however, I never liked math class and the ways most of my teachers taught. George has been teaching me for two months so far and I feel like he has opened a whole new door of math for me. He has taught me many new topics and new ways to think. I really enjoy learning from George and I am very thankful that I was able to meet such a great teacher.”
✏️ “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.”
✏️ “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!”
✏️ “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!”
✏️ “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!”
✏️ “The first time I took an SAT math practice test, I scored a 540. I was confident in my math skills, but I still scored quite low. After learning with George, I realized that my problem solving skills were not refined. George taught me how to think. The SAT math section does not actually have any extremely difficult math. The real tough part is solving a problem efficiently and accurately. George taught me how to connect many topics of math together to do this. By the time I was ready to take the real SAT, I was scoring 800’s on the practice tests.” (800 Math SAT)
✏️ “George worked with my son all summer to help him improve his math skills for the SAT’s. He’s enabled my son to feel more confident, and he has certainly instilled him with stronger math skills in preparation for the test – and equally important – for his future education. We’re hoping for good results on the SAT! We thank George for his ability to provide personal individual attention to our son.”
✏️ “Anyone who says that the SAT Mathematics section cannot be taught has not met George. After scoring a low 600 on my first practice exam, George stepped me through the process of learning how to take the test as well as the mathematical concepts behind it. After several months of training, George helped me to receive a perfect 800 on the Math section. And if that wasn’t enough, he also guided me through the SAT Mathematics IIC Subject Test, which, with his aid, I scored another perfect 800. Thanks to George, I was able to conquer the SAT’s.”
✏️ “I have been working with George for about six months and I have never seen myself improve this drastically. I achieved a 5 on my AP exam and a 770 on my SAT Math. I truly owe it all to George.”
✏️ “In preparing for the SAT, George helped me dissect each problem into its basic parts. There is no better preparation for the Math SAT than with George.”
✏️ “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!”
✏️ “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.”
✏️ “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.”
✏️ “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 is a very sound investment for parents seeking to help a struggling student. George genuinely cares about the teaching aspect of education and his concerns are focused on ensuring the student understands each concept thoroughly. He recognizes that while grades are the formal measurement of results, just as important is the student’s confidence level and comfort with the subject matter. As a consequence, our daughter’s grade rose from a C- to an A- in two months, but equally satisfying is seeing her growing confidence in herself and her abilities.”
✏️ “During junior year, Perdocere helped me prepare for several standardized tests in both math and science. Perdocere was distinctly more effective than the other tutoring organizations I tried. With Perdocere’s help, I earned a 740 on the math portion of the SAT I, a 760 on the SAT II Physics, and a 5 on the AP Physics B exam. George helped focus my hard work and succeed where I had to.”
✏️ “George has made such a big difference for our child – academically and personally.”
✏️ “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.”
✏️ “George makes sure his students believe in themselves and their abilities, thus setting the stage for academic success. He also takes the time to emphasize that it isn’t inspiration that creates success, it is perspiration. It is the mantra that is followed as he prepares students for the SAT. And there is success; both of our sons have done extremely well on both the SAT and SAT Subject Tests – and by extremely well, we mean a consistent pattern of scores at or just below 800.”
✏️ “I am happy to have George as my daughter’s tutor. He is thorough and organized and has helped my daughter understand the subject better. I am pleased with my daughter’s improved performance in her school quizzes and tests. I highly recommend George.”
✏️ “George brought my daughter’s math grades up from C- to A’s. He works well with my daughter and is very positive.”
✏️ “Thank you for all that you do for our son!”
✏️ “I missed a year and a half of school and George has been very helpful in getting me caught up in math.”
✏️ “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)
✏️ “It is with both pleasure and sadness that I write this testimonial for George who has tutored my three children over the last five years in a wide range of subjects (math, pre-calculus, chemistry, physics, biology, computer science, and a little engineering on occasion). George has been an extraordinary resource and has become an honorary family member and a dear friend to me and all my children. He has seen my children through quizzes and tests, helped with tricky homework assignments, and led them to superlative performances on their SATs, APs and ACTs. George has been a terrific mentor as well as a tutor, giving advice on school, the college application process, and the like. George keeps up to date with all assignments posted by the school and helps even disorganized kids get organized. He is terrific at reminding the kids of deadlines for projects, assignments, quizzes and standardized tests. He has always made time in his busy schedule for extra sessions when a big test or project is due, he explains why and how rather than tell a student just to apply the formula, he adjusts his method and style of tutoring to each individual child, he is reliable and efficient and always pleasant, and his range of subject matter knowledge is superb. I honestly believe that George’s tutoring has had a big and most positive impact on my children in many ways. On the most obvious level, he truly did help boost their test scores and probably did impact the level of college to which they were admitted. Beyond that, however, he really gave them a greater appreciation and understanding of subject matters that they were not as comfortable with, and gave them the tools to help them think, analyze and solve. These are tools that they will carry with them and use all their lives, whether they ever take another math course or not. That is what a real tutor does not just get you through the next exam. And even further, George honestly cares about his students not just their performance but also their minds, their interests, and their character. Whenever my two oldest are home from college, they are delighted to see George again, and I know that my youngest will miss George when he starts college this year, as will I. George has been a big part of our lives. We are better of for the experience in many, many ways. Thank you, George.”
✏️ “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.”
✏️ “George is a very relaxed, but serious tutor, making every session fun while also imparting incredible amounts of math knowledge. It is because of my sessions with George that I realized how much I love math and it is now my favorite subject. I have earned a straight A in math this year thanks to George.”
✏️ “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)
✏️ “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!’ ”
✏️ “Math has never been my forte – even though George tells me I’m good at it every time I meet with him. Which in a way is true – because when George is teaching me I am good at math. Instead of only showing me how something works, he’ll explain why it works, which is exactly the teaching style I need. The difference in style, and therefore effectiveness, between George and my teachers at school is so vast that there’s a distinct possibility I would be failing math without him.”
✏️ “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)
✏️ “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 is a godsend. He breaks math down in a language students understand while making the process enjoyable. By laying out the mechanics of math, he lays down a foundation for comprehension the student carries forward throughout their academic career. He also gets results. My son quickly grasped the concepts and went from a C+/B- student to an A student. He also moved up two class levels in his math placement. His improvement correlated directly with his confidence, which soared. He now thinks of himself as the math guy. The greatest compliment is that I recently asked him what he wants to be when he grows up and he said a math teacher.”
✏️ “George has expanded my interest and ability in math while working with him this past school year. I have really learned a lot as well as a positive and reliable approach to math. It has been a great experience working with George and I am looking forward to working with him to prep for the SAT’s.” (790 SAT Math)
✏️ “You are the best!”
