“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
✏️ “Following a couple of years with disappointing math teachers, my son was struggling in his Algebra 2 course – and then the pandemic hit, and distance learning compounded his problems. At this point we reached out to George. George took the time to work back through the older material to build up a strong foundation for future success. The first few months were triage; even so, we noticed improvements in performance almost immediately. In addition to laying a strong mathematical foundation, George has done a great job teaching my son solid study habits and test-taking strategies. My son is comfortable with the material and confident that he will perform well on his tests. I am certain that my son is now on a trajectory that will guarantee success in math through the end of high school and beyond.”
✏️ “A word of advice: start with George early. Building the proper foundation in math is crucial to getting good grades in all years of high school as well as good SAT math scores.”
✏️ “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 SAT 800, 36 on the ACT Math, and 99% in Math Honors Pre-Calculus. In the time that we have worked with George that was the result. I do not believe anybody could have achieved better results. George, however, makes it look easy. What else can you say.”
✏️ “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!”
✏️ “George has been working with my son for the school year and his Math grade has moved up by a full grade. More importantly, he now has a solid understanding of Algebra as he moves on to High School. My son’s confidence level has soared too. George knows what is important and he makes the experience fun as well.”
✏️ “Whether in a group or individually George is by far the best tutor I have had. His knowledge is extensive and he teaches in a way that complex subjects are easy to understand. I’ve used other tutors and centers and none compare to George. He is such a great teacher that I kept bugging him to teach at my high school.”
✏️ “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!’ ”
✏️ “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 brought my daughter’s math grades up from C- to A’s. He works well with my daughter and is very positive.”
✏️ “After reviewing the yellow insert in the newspaper, I made a note to myself: Call Perdocere? I wondered: What does Perdocere mean? After my daughter’s ACT math results, I felt it was important to take action, so yes I did call Perdocere and spoke with George. After listening to our story, George met with my daughter to begin immediate math tutoring. We had limited time, six months, to accomplish a lot of learning in order to achieve a more successful math test score. Equally important, my daughter was to improve on her math for success when at college. George is a brilliant and enthusiastic teacher. He shared his plan with us and we quickly moved ahead. He had my daughter take both the SAT and ACT practice tests to see which would be best for her. He watched her to see how she worked. He prevailed upon our busy schedule for intense tutoring. George expects a lot from his student, but he gives much in return. For my daughter, she learned that math from him, and he instilled confidence. For me, he kept me in the loop and patiently worked with our schedule. At the six month point my daughter retook the test with George’s best wishes (and his calculator as her calculator shut down days before the test), and she exceeded her goal. Perdocere means to instruct thoroughly, Perdocere is George! Thank you!”
✏️ “George has been a helpful, effective tutor whom I would recommend to most anyone. He quickly shows you everything there is to know about SAT math and installs it into your memory. Furthermore he is a nice guy who genuinely wants you to improve.”
✏️ “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’.”
✏️ “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.”
✏️ “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)
✏️ “This is exactly what we have discovered in George – To Teach or Instruct Thoroughly. George not only has read our son’s Advanced Algebra book, he has wrapped himself around it. He teaches with enthusiasm and a deep concern for our son. He genuinely cares that our son not only understands the many different concepts but also makes sure that our son is able to effectively apply them. Our son has 125 new problems every week and George makes sure our son fully understands each and every one. Our son’s grade has improved from a B- to an A- and we expect this trend to continue along with his growing mathematical confidence. Our son smiles broadly at the end of every session. George is the MVP of the academic playing field! 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)
✏️ “I’ve been working with George for close to three years now and he is unlike any other tutor I’ve had previously. With comprehension comes good grades and self satisfaction I can’t get through just memorization. George’s plethora of knowledge has helped me through numerous courses and standardized tests. Whether it be science, math, and even the SATs, George has been there to help me.”
✏️ “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 tutored my daughter in math this summer. He clearly has knowledge and patience to tutor with confidence. He took pride in making sure my daughter understood the material covered, without tests and grades, only with positive feedback and enthusiasm. Thank you.”
✏️ “This year our son attended the Perdocere Math SAT Prep Course. George’s clear, well-presented explanations and thorough review of the SAT Math was very helpful. We finally found someone with a high-level math knowledge base and also with the unique and most important quality – the skill of teaching in a manner that is understandable. George has helped our son gain knowledge, skill and confidence.”
✏️ “George taught me a new way of thinking. He retrained my brain to think the way he does. I never have to memorize formulas, or remember a certain method. George taught me how to analyze the core math behind a problem, and derive how to solve it on the spot. It is a skill that has paid off incredibly. Thank you George!!”
✏️ “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.”
✏️ “My daughter went up two letter grades from a C to an A. In my book George gets an A+.”
✏️ “George has helped me to understand algebra better than my teachers at school ever could!”
✏️ “The SAT Subject Test for Math Level 2C is not like the normal SAT math section. The normal SAT math section has easy math that really just tests one’s problem solving skills. On the Math Level 2C test, both one’s math skills and problem solving skills are tested with more rigor. George taught me how to link all the topics I needed for the test and more to allow me to see many different methods of solving each problem. On top of that, he taught me how to pick the most efficient and accurate method so I would have plenty of time to spare to check my answers of at the end of the test. Because he taught me how to connect so many topics, sometimes solving one problem a certain way would reveal the solution for another problem on the practice tests. On the practice tests I was able to score very high with ample time left, and on the actual test I scored a 780.”
✏️ “When George takes on a student, for him it is not just a job, for him it is a commitment which he honors spectacularly. A commitment to help you do well in school and also a commitment to actually learn the subject matter.”
✏️ “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.”
✏️ “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 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!!”
✏️ “George is the best teacher I ever had.” (780 Math Level IIC, A in Level 1 Precalculus)
✏️ “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 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.”
✏️ “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.”
✏️ “I wish all students could have the opportunity to have such an excellent teacher.”
✏️ “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.”
✏️ “Ever since I began my sessions with George, I have significantly improved my mathematical skills and have consistently been able to maintain high test scores. George has restructured my foundation and constantly solidifies key concepts, which help me to take each problem step-by-step and achieve the correct answer while truly learning the material. George not only helps to get the correct answer but also goes far beyond what is asked and works out multiple solutions to the simplest and most difficult problems. George is able to break down problems into manageable pieces unlike any other math teacher I have ever had. I commend George for his knowledge on the subject. I know with George’s help and positive attitude, I am confident that I will do well. Without George both my algebra and chemistry skills would be nothing like they are today. Thanks George and I can’t wait for another successful year!”
✏️ “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 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.”
✏️ “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 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.”
✏️ “As an extraordinary tutor for classroom math in both middle school and high school, we have now asked George to prepare our daughter for math on the college SAT. We have absolute confidence in George to help our daughter achieve her highest possible SAT math score.”
✏️ “Our middle school son started to have difficulties in mathematics. After working with him, George was able to assess and pinpoint his areas of difficulty. In addition, George had the patience and teaching strategies that worked with our son. Now he enjoys the challenge of math and feels so much better about his abilities. His grades have gone from a C+ to a B+, and now A’s.”
✏️ “Even though my strength has always been in writing and English, I am now an A student in math and science as well because of George.”
✏️ “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)
✏️ “George plainly has a mastery of math and science that runs both broad and deep, and he is very, very good at communicating with both students and parents in clear English pitched to their level of scientific understanding, wherever that may be. He clearly cares about his students, and we feel very confident that he is happy to help any way he can.”
✏️ “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.”
✏️ “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.”
✏️ “George is the real deal. Not only does he have a stellar educational background and a wealth of experience, but he has the tutorial skills to impart various math concepts and a real gift for connecting with students. My son has happily worked with George for five years; during that time, he consistently has brought home A’s. Simply put, George is the best there is.”
