“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 is a great tutor and is a great person to work with and not only has helped me learn, but also improve the quality of my work and has helped me change my style of doing math into an easier and more comprehensible method.”
✏️ “George has worked with our boy for the past eighteen months. The improvement in his grades, as well as his overall approach to school work has been amazing. His own words sum it up ‘George taught me a new way of thinking. He retrained my brain to think the way he does’.”
✏️ “Far more than a brilliant teacher, George’s warm and positive attitude has been truly therapeutic by giving our daughter a new confidence and competence in math.”
✏️ “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?” ”
✏️ “I’m in honors math. However, I couldn’t handle Algebra-II as well as Honors Geometry. So my grade began to slip so my parents called George. It was the best decision. George knows everything about math and he was able to guide me through the daunting path of Algebra-II and Trigonometry. He made everything less intimidating, and within no time, my grade was back up. George is definitely going to be my tutor next year.”
✏️ “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.”
✏️ “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.”
✏️ “I am very impressed and happy with George as a tutor for my daughter. With his extensive knowledge, he can instruct her in both math and science, both for the classroom and SAT prep. I think he is very patient as he works with the student and is able to quickly discover how best to work with them.”
✏️ “Thanks to George I am getting an A in honors pre-calculus. Not only am I understanding the material fully, I find myself thinking outside the curriculum and trying to learn more advanced math. Only George could have taught me this high a level of math, and he is currently preparing me for advanced placement BC calculus. I am 100% confident George will help me conquer that class too.” (800 SAT Math, 800 SAT Math Level 2 Subject Test, 36 ACT Math)
✏️ “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 instructed our son and now our daughter. We have found that George tailors his teachings to meet our children’s individual needs and not just the ‘text book’. George covers everything and then he covers it again making sure they understand thoroughly. It is with great confidence and pleasure that we recommend George to be the very best available!”
✏️ “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.”
✏️ “George is a truly amazing teacher. Not only is he incredible capable and knowledgeable but also sincere and caring. He knows how to captivate a student’s focus and how to motivate them. There is nobody better than George!”
✏️ “I cannot express my gratitude to George who is devoted to my son’s education. George ensures that the time spent is productive. My son’s experience has been excellent, and the results were exceptional. George is not only the best math teacher for my son but also a mentor who helps him open new doors for the future.”
✏️ “George is an excellent teacher because my daughter’s grade in math has gone from a C+ to an A through out the school year.”
✏️ “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 is very involved in making sure our son is studying the material he needs to succeed and getting a clear understanding of what is expected of him. George takes time each week to prepare for our son as an individual. Our son enjoys the way George teaches him; it’s a great mix of teaching and really caring about the student. We know George was the right choice, our son went from failing to passing with an A.”
✏️ “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 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 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!”
✏️ “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 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!”
✏️ “George is the best tutor out there. With his thorough teaching, he has increased my Math SAT score by over 200 points in the past year. Since the eighth grade, George and I have been working to increase my math grades at school, and together we have been nothing but a great success. George is extremely talented. I think that to him, Perdocere is more than a clever Latin name for his tutoring business, it’s a philosophy. George knows everything about the system, whether it be public school, the SAT, or math in general. He didn’t acquire this knowledge through tricks and memorization. He learned it through simply learning the math thoroughly. I can speak from experience. Once George and I had conquered Algebra, I had the skills to conquer problems that would have been insurmountable to me just a few months before. It’s quite simple. It all comes down to his philosophy of teaching thoroughly. George produces results.”
✏️ “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 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.”
✏️ “George is a natural; he not only tutors but teaches the student how to study and how to approach each subject. Math becomes an enjoyable experience. His teaching habits take over and the student shows a remarkable improvement in his all around school work. His method of cultivating a close relation with the student and his involvement in their overall school work is producing great results. I only wish we had someone like George when I went to school.”
✏️ “My senior year brought with it an abundance of math challenges. I had decided to enroll in BC Calculus, as well as take the Math II SAT2. I never considered myself to be particularly good at math, so I was very worried about how my various math undertakings would pan out – but, under George’s tutelage, I ended up doing better than I could have ever expected. Often investing extra time into lessons, George Patiently taught me enough about precalculus and calculus to raise my average SAT2 by more than 180 points and nudge my math grade to an A. George takes the time to explain the underpinnings of each theorem, never resorting to memorization when there is understanding to be had. Whenever I brought my confusions to George, he could explain with perfect clarity what had gone wrong in my calculations. Two years ago, I never would have envisioned myself having my current relationship with math – one where I can look forward to new challenges rather than dread tests and quizzes. Without George’s unparalleled skill as a teacher, I would never have improved in math to the point that I have. As a student, I cannot recommend George highly enough. More than achieve tangible results in terms of grades and numbers, I have developed an entirely new attitude towards mathematics thanks to George.”
✏️ “George has 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.”
✏️ “Having George as my math and chemistry tutor was a very very different experience compared to other tutors. He could identify exactly what I needed not just in terms of the things I was studying but also in terms of the broader plan. His teaching method was also very patient, effective, and thorough, and I could understand all the material with ease. Having tutoring sessions with him has taught me much more than math and chemistry. I also learned many other things such as study methods. He is a highly recommended tutor.”
✏️ “In teaching me how to do math for the SAT’s, George has taught how to work around any math problem that I may come across.”
✏️ “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)
✏️ “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 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.”
✏️ “I love working with George. He is so intelligent and can explain concepts in so many ways that it is easy for me to understand. What I appreciated the most is how supportive he is. He makes me feel that I can achieve anything!”
✏️ “My son is a freshman in honors geometry – a really tough course!! George has been instrumental in explaining the concepts, teaching him how to solve the theorems and encouraging him throughout the year. Without this assistance – this year would have been much tougher. The insight into my son’s learning style and his clear and thorough explanations of each concept have given my son the confidence to tackle this vigorous course. He looks forward to meeting with George and doing his math.”
✏️ “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.”
✏️ “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.”
✏️ “George is the best math teacher I have ever had. Nearly all of my math teachers in the past either just read the textbook to the class or followed a set of curriculum notes so closely that all you had to do was memorize then regurgitate exactly what you just learned to get an A. In the past, math class was no less than a memory game where each problem only had one solution which was shown by the teacher. George does not follow a textbook and he can create a lesson around a single problem. He shows many solutions to the simplest of problems and show how to connect every topic to each other, so I can fully understand each aspect of the topic we are focusing on.” (perfect score, freshman college math placement)
✏️ “What a revelation to learn that instead of being bad in math, our daughter just wasn’t being taught in the manner in which she learns best. George identified her individual learning style and the results have been astonishing. He does a superb job of dovetailing his tutoring of math at the high school level with his preparatory course for the math portion of the SAT.”
✏️ “I’m proud of my accomplishments since he has worked with me.”
✏️ "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 gave our son the tools and confidence to achieve results above and beyond what he believed was possible. He is a terrific teacher.” (college student parents)
✏️ “Throughout the SAT math class, George has made all the questions that are considered hard seem so easy. He has also shown me different ways to come up with an answer for each question. This has caused my math grades to improve!”
✏️ “800 – we thought that sort of score was something unattainable – something that only a few gifted students achieved. And now our son (who we love dearly but never considered to be a particularly gifted math student) has brought home 800s twice – once on the SAT and once on the SAT II. We attribute so much of this achievement to George. He restructured fundamentals and taught our son to enjoy math once again. George consistently challenged and pushed – but never too much. He displayed patience and a wonderful gift for explaining things. As our son told us, George not only works through problems but teaches how everything evolved and why everything is what it is. We couldn’t ask for a better teacher. We really don’t have enough adjectives to describe George’s teaching ability. He is absolutely the best teacher that we have ever seen!!! George – your job with number one son is almost done – it is now time to move to number two.” (800 Math SAT, 800 Math IIC Subject Test)
✏️ “George’s teaching has not only allowed me to conquer complex calculus problems, but has also taught me the specific processes needed in order to crack several SAT problems. Immediately after entering Advanced Pre-Calculus my junior year I fell behind, unable to solve problems and make critical connections. However, with George’s help, I improved dramatically, impressing not only myself, but also my teacher. I ended up finishing the year with an A, a real feat in the challenging math department at my school. After George boosted my confidence in solving problems, particularly by breaking them down into manageable pieces and explaining proofs behind equations, I knew I could take on the rigorous AP Calculus course at my high school. Sure enough, his relentless attitude and determined spirit earned me an A for the first trimester and on my midterm exam. After starting with George in the 9th grade, I would have never thought that I could make it this far. Our compatible personalities and George’s vested interest in my success led me to gain a high SAT score and consistently excellent grades. For George it is never ‘I can’t do this,’ but rather ‘how can we solve this problem in more than one way to truly understand the concept?’ I am confident that George has provided me with a solid foundation that will allow me to succeed in college mathematics and ultimately my desired career path.”
✏️ “I used to hate math and everything to do with it. But now that I’ve been working with George and I am ahead in my work, I absolutely love math now. I can’t even tell you the satisfaction I get when I know all the math in class the first time the teacher tells us. Also, my grades couldn’t be better right now, and it is all due to George”
✏️ “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)
✏️ “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.”
✏️ “I met George in February of my junior year. Earlier in my junior year and sophomore spring, I had been bounced between countless math tutors who seemed uninterested in actually changing the way I learn and comprehend math on different levels, which is a necessary transition from my school math course work to solving problems on the ACT. A few had deemed me incapable of ever truly raising my math IQ and relied heavily on strategy to get me through standardized testing problems. Yet with George, everything changed. He studied the way I learned and took tests, and synthesized the information I gleaned from each of our sessions. He then broke down my entire bank of knowledge in the realm of mathematics and we started from the bottom, building our way up. As each new brick was laid in the foundation, my confidence grew and my ability to take control of the ACT in a way that worked for me was apparent. I no longer fear ACT test day, new units in Pre-calculus or a problem that seems overwhelmingly difficult based on its exterior. George became my math savior and I can not thank him enough.”
✏️ “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.”
