“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 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.”
✏️ “What would our schools be like is we could witness George’s way of teaching there? Quality, it works!”
✏️ “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.”
✏️ “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 knows exactly how to prepare you for standardized tests. He provides you with more than enough preparation to succeed. I worked with George for about eighteen months, and I got an 800 on the math SAT, a 36 on the ACT math, and a 99% on my final exam in honors pre-calculus. Only George can bring the perfectionist out of you.”
✏️ “Thank you so much for all you do for our son, and for us!”
✏️ “Dear George. You saved the day. Or rather, the semester. The few sessions you spent with our son made a world of difference – not only to his grade but to his state of mind. You showed him not only that he could grasp the concepts of his math class, but that he could enjoy the process. Thank you, thank you, thank you. We are forever grateful.”
✏️ “Along with information, George offers support, encouragement and understanding. He communicates complex ideas in a very comprehensible way.”
✏️ “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.”
✏️ “It’s a privilege to have Dr. George tutor you.” (800 SAT Math)
✏️ “George is awesome. He pushes me hard, but it is because he knows I can do it. George is so smart. He has a thorough knowledge of all the material and he makes sure that I learn it just as completely. His one-on-one sessions really give me a chance to get a better grip on what we are learning in class and to explore deeper some of the things we do not get a chance to spend a lot of time on in school. As a result, I am a very confident math student.”
✏️ “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.”
✏️ “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)
✏️ “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.”
✏️ “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.”
✏️ “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.”
✏️ “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.”
✏️ “George re-defines the definition of tutor. We have never met anyone with his credentials, mastery of the subject and infinite sense of caring and can-do attitude. The stress level as it relates to school work has gone way down in our home since he began tutoring our daughter. We only wish we had met him years sooner.”
✏️ “Within the last two years, George not only fulfilled his duties as a tutor by helping me excel in Calculus and on the SAT’s but went beyond by helping me with the college application process and advising me based on my academic goals. Through out George mentored me and helped me to grow and develop the strong work ethic and skills that I have today and use every day in college.”
✏️ “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)
✏️ “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 son’s entire success this year is because of Dr. George and his smart and savvy Perdocere Math Tutoring! With Dr. Georges innate knowledge of the academic world we feel confident that we are steering our son in the absolute right direction towards his passion for learning, achieving and most importantly to his happy and bright academic future! We will continue to supplement our child’s education with Perdocere Tutoring because Dr. George has given him the confidence we only dreamed he could achieve! Thank you from the bottom of our hearts!”
✏️ “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 has been an excellent tutor and mentor to me. When I started with him I was failing my geometry class. Within only a couple months he helped my grade go up by three grade letters. Thanks to him I will be finishing the years with a solid grade. Not only has he helped me academically but he has also made me more confident in my classes and work. At my hardest struggle, George took his time to spend many extra hours with me. He teachers like no other teacher and is able to make strong connections with his students while teaching the best techniques and strategies to solving problems.”
✏️ “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 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.”
✏️ “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.”
✏️ “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.”
✏️ “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.”
✏️ “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 was everything we’d hoped for in an SAT tutor – and more. Just by the enthusiasm our son had for completing the between-session assignments (‘George work’ often came before homework!), we knew we’d made the right choice. Not only did he feel totally confident taking the SAT, his time with George helped him sharpen his ability to complete regular school assignments, as well; he is now tackling honors calculus with ease. Our son fully recognizes how much he benefited from George’s coaching: when his math SAT score came back 130 points over his first attempt, he said: ‘Way to go, George!’ ”
✏️ “Who you gonna call?? We have relied on George for both of our daughters in tutoring Mathematics and Chemistry. I noticed George’s ads, called him and the rest is history. For my older daughter, we began seeing George in the second half of her junior year. She needed a quick review for her upcoming SAT, after having scored in the 600’s for her PSAT. She received a 730 on her first try. In addition, my daughter was struggling in her Precalculus course, despite studying under a different tutor earlier in the year. George salvaged my daughter’s junior year math grade, and she ended the year with an A-, after a rocky first half. He takes a very methodical approach to teaching, and doesn’t believe in shortcuts. To excel, the student must understand the concepts, and not simply memorize rules. We called on George again to help my daughter through her senior year Calculus BC course, as well as to tutor her for the retest of the SATs, for the Math II exam and for her AP exam in BC Calculus. Needless to say, the results were stellar. She improved her SAT math score to a 780; received a 790 on her Math IIC exam; eeked out an A- in her BC Calculus course for the year, and topped it off with a 5 on her AP BC Calculus exam. She was thrilled particularly with the AP score, because it satisfied her Math requirement in college. But guess what? She may become a Computer Sciences major, and is probably going to have to take a lot more math. And she can approach college math with confidence, given the solid foundation George provided her. My younger daughter is a junior in high school and is taking AP Chemistry. She loves the subject, but was finding the subject matter increasingly challenging during the fall semester. We called George, he taught her for three sessions and she was thrilled to get an A on her mid-term, and an A for the fall semester. She was impressed with his thorough understanding not only of the subject matter, but of how the teacher required questions to be answered. He discerned that the teacher required responses that exactly followed the AP test… my daughter adjusted her answers accordingly. I think we are going to have to call on George again soon…the material is becoming challenging again, significantly more difficult than the questions on the Chemistry AP exam, and we take comfort in knowing he has complete mastery of the material and boy, does he know how to teach! — A happy parent.”
✏️ “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.”
✏️ “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.”
✏️ “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.”
✏️ “George has reinvigorated my son’s interest in math and confidence in his abilities. Each week, George would carefully focus on classroom assignments, while bolstering broader areas of study. Lessons were purposeful, positive experiences, which immediately translated into improved test scores and a more meaningful understanding of concepts. My son was able to introduce advanced strategies in the classroom, and his teachers consistently remarked that his contributions greatly enhanced their class discussions. George has a warm personality and a true gift for teaching material in a compelling, yet fun, manner. My son truly enjoyed the experience of working with George, and has emerged as a far stronger student for it.”
✏️ “Working with George has improved my math skills immeasurably. I was able to achieve a near perfect score on my Math SAT as a result of George’s dedication, patience, and skill in our tutoring sessions. He made sure I not only understood the concepts but had a deep knowledge of them. I also worked on my school work with George and felt that our work together put me well ahead of my fellow students.” (790 SAT Math)
✏️ “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 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.”
✏️ “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.”
✏️ “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!!!”
✏️ “George’s capabilities extend well through college topics. After taking BC calculus my senior year of high school, I took a semester off before taking Calculus III in the spring term. What began as a speed review of single-variable calculus expanded to encompass numerous topics neglected in the high school curriculum, as well as proper explanations and proofs of many other topics. George’s first goal is to establish a solid mathematical foundation; or in a case like mine, backfill the incomplete foundation. From there, working into sciences or high level math becomes far easier.” (800 SAT Math)
✏️ “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.”
✏️ “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.”
✏️ “The best tutor we have ever had, and the nicest!”
✏️ “George has been one of the greatest things to ever happen to me. Before George, I was struggling and basically failing math. Since I’ve worked with so many other tutors who completely failed me, I was a little apprehensive when I first met George but we soon became totally comfortable working with each other and even have inside jokes. He’s helped me in math so much. I used to hate math with a passion, but now it’s one of my easiest and most enjoyable subjects. George and I work together even if I’m sick. He makes me feel better, instead of wearing me out. If I have a bad day at school, George cheers me up. He’s basically your best friend and the best tutor. I love him! Thank you George!”
✏️ “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.”
✏️ “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.”
✏️ “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.”
✏️ “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.”
