“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
✏️ “Once your child has worked with George, you realize what an extraordinary teacher he truly is. George not only teaches in a professional and organized manner, he has instilled self-confidence in our son that goes beyond mathematics. Our son respects George not only for his ability to teach him, but also because he takes an interest in him personally. George not only gives careful consideration about what is being taught now, but what skills will be needed in the future. Our son took a higher level mathematics course this year than was recommended, and with George’s help he was very successful! He is a wonderful mentor, something we never expected! Thank you George!!!”
✏️ “Thank you so much for all you do for our son, and for us!”
✏️ “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.”
✏️ “George is a wonderful example of a professional instructor for mathematics and science. The quality of instruction administered in a calm, patient, and open manner reflects his true concern for the student. The dialog that exists between teacher and student is superb, as the knowledge that is sought and shared establishes itself. We are glad that academia has produced such a top notch instructor for our son.”
✏️ “Our daughter would have never gotten accepted to the highly selective college she now attends without George. Meaning she would have missed the opportunity to go to the school that’s turned out to be perfect for her. We thank our lucky stars for George every single day.”
✏️ “George knows his math. His educational accomplishments speak for themselves as does his many years of experience tutoring the subject. He has done a great job with my son. He has awakened his love of math. He simplifies where it is complex and enriches where it is too simple, balancing the subject and keeping my son engaged. This year my son has earned an A in math so obviously he gets results. More than that, George is a great person and my son truly looks forward to and enjoys his sessions. Working with George was one of the best decisions I ever made.”
✏️ “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!”
✏️ “I have had many math teachers in the past, but I have never had a math teacher like George. George is the best math teacher I have ever had; no other teacher I have ever had can even compare. It seems like my other teachers has a lesson plan and tried to make me adapt with the lesson plan. George builds his lessons around what I am capable of, so each lesson is completely learned to its fullest. He has even helped me catch up after past teachers have brought me down and held me back. I am extremely thankful that I was able to meet and learn from George, and I hope I can continue to learn from him.” (‘A’ in Honors Pre-Calculus)
✏️ “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.”
✏️ “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 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)
✏️ “During my sophomore year in high school, before I began tutoring with George, I worried constantly about the effect my math grade would have on my grade point average. George started teaching me during the beginning of my junior year, and now, having graduated from high school, I can look back and say that George’s superb skills as a tutor led me from getting B’s in Algebra II to A’s in BC Calculus. Thanks to George, math stopped being a constant source of worry for me and became a course that helped me maintain my GPA. I studied under George for two years, and my attitude towards mathematics changed immensely during that time. George’s patience and creativity make him an ideal tutor for both struggling students and those who wish to broaden their understanding of mathematical concepts.” (770 SAT Math, 770 SAT Math IIC)
✏️ “George tutored our daughter for almost a year. He is a one of a kind teacher because he is so good as what he does. Our daughter said that George was able to teach her math concepts in such a way that she really understood the topics. Prior to George she was able to get through Algebra and Geometry courses with good grades but without understanding the material. George is very dedicated, very enthusiastic and really knows how to teach for understanding. He is also patient and positive and was good for my daughter’s confidence. She liked him very much which is always important too. I am not a fan of today ‘s highly pressured academic rat race, and I believe children are suffering mentally and physically. However, having a good tutor can really help certain students to succeed rather than just stumble through.” (U.S. exchange student, online tutoring, Viterbo, Italy)
✏️ “In 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.”
✏️ “He has genuine passion for teaching in its most basic sense. His subject knowledge and teaching style encourages our child’s participation in a planned roadmap for success.”
✏️ “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 the best math teacher I have ever had the pleasure of working with. Before I met George I had a 670 on my math SAT, and now I am getting 800’s consistently. I owe it all to George because he is constantly pushing me to work hard to achieve my goals. He teaches me more than I need to know so that I understand all the math on a higher level. George has always supported me and has made me a better learner.” (800 SAT math)
✏️ “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.”
✏️ “It’s a privilege to have Dr. George tutor you.” (800 SAT Math)
✏️ “George’s stand-out credentials and many years of experience made him our first choice when we searched for a math tutor for our high school-aged grandson. As it turns out, George’s singular talents go far beyond these qualifications. He quickly established a genuine rapport with our grandson and made a thorough assessment of his academic strengths and weaknesses. In this context, he went back and rebuilt our grandson’s foundations in math, filling in gaps that would no doubt have become increasingly problematic in the coming years. He improved our grandson’s attitude toward learning and noticeably grew his confidence. He showed him what and how to study and how to apply his new knowledge effectively. George’s mentorship has surpassed our expectations and has proven to be an invaluable asset for our grandson. We are very pleased to have found him and recommend him highly.”
✏️ “The best tutor we have ever had, and the nicest!”
✏️ “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.”
✏️ “My son has been tutored by George for the last three years. During that time he has gone from a struggling student to one who feels a confident mastery of the subject. George has built up his understanding by patiently explaining the basic foundation of math as well as adding enrichment when my son was ready. He now loves math and we owe it all to George!”
✏️ “George is the best math teacher I have ever had and for the first time in my life I can now say I feel confident in math. I get it! He is so organized. He challenged me to really push the limit and had confidence in me that I could achieve the goals we set together. I wasn’t to sure but with his methods, encouragement and great teaching I did it and feel great about it too. I did greats on my SATs, my math grade is an A and I now will enter the honors level. I wish I had met George earlier. Thanks George.”
✏️ “I wish all students could have the opportunity to have such an excellent teacher.”
✏️ “Thank you for all that you do for our son!”
✏️ “Beginning with the very first session, my school work became much easier. George helps me understand math in a way I never did before.”
✏️ “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 have been extremely happy with George tutoring my son for honors Geometry in his first year of high school. My son had a difficult transition to the rigor and demands of high school for which he was not prepared coming from a quite weak math background from middle school. George became his tutor in the most complete sense of tutoring, meaning that he did not only teach my son all the concepts in a way he could understand and without memorization but also gave him a method to study and trained him to think and solve problems. This allowed my son to regain his confidence and to learn how to study not just math but other subjects as well. George’s dedication, for all aspects that could benefit my son impressed me from the beginning. He knew from the start how to engage him, how to make him confront difficulty in a rational way, something that requires besides a deep understanding of the technical concepts a strong educational knowledge and experience. I will recommend George without hesitation to anyone that wants to truly understand math and succeed in academics.”
✏️ “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 has helped me to understand algebra better than my teachers at school ever could!”
✏️ “Having George help me kept a smile on my face. I was never left hanging before a big test.”
✏️ “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!”
✏️ “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’s math skills and patient manner have increased my son’s confidence and competency in his own math skills. He is able to explain complicated math concepts in simple terms while making the process enjoyable. George’s enthusiasm for math is contagious and helps ensure his students to be equally enthusiastic.”
✏️ “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)
✏️ “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’.”
✏️ “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!!”
✏️ “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)
✏️ “Our son was diagnosed with lymphoma during his freshman year and has been out of school for a year and a half. In addition to feeling sick from all of the chemo treatments, he was feeling hopeless that he would ever be able to catch up with his schoolwork. What he wanted the most was to catch up in math – Algebra II. George was the answer. For almost a year now George has been teaching him in our home for 4-6 hours a week. Not only is he catching up but he is also maintaining an A average and he will be able to enter his junior year this fall feeling completely confident in his math knowledge. We are so grateful to George for that. Although he has a long way to go catching up in all his other subjects and he still has another six months on chemo treatment, he is ready to get back to his life as a normal high school student. Couldn’t have done it without George! Thank you for your dedication to our son – mathematically and emotionally!!”
“George is a great tutor and a very nice person to talk to. I would recommend him for anyone.”
✏️ “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!”
✏️ “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 is the best math tutor imaginable.”
✏️ “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)
✏️ “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 great tutor. His math knowledge and his ability to teach it in such a way that my son understood it was amazing. My son improved his Math SAT score by almost 100 points. I highly recommend George both as a tutor and as a person. He made a huge impression on my son. Thank you so much.”
✏️ “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)
✏️ “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!”
✏️ “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!”
✏️ “Thanks again for everything you have done for the boys – you really have a gift!!”
