“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 the best teacher I ever had.” (780 Math Level IIC, A in Level 1 Precalculus)
✏️ “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.”
✏️ “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.”
✏️ “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!”
✏️ “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)
✏️ “George recreates the art of tutoring: he is like a muse who inspires learning as an art.”
✏️ “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!’ ”
✏️ “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 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, many, many thanks for all your hard work with our son. You were the only outside tutor we used that truly put your heart and soul into his success – from identifying weak areas to intensively reinforcing all areas. His results speak volumes about how you opened up his understanding of math (and helped jack his score up to a very competitive level). Personally, your commitment and steadfast resolve towards his SAT results was remarkable.” (740 SAT Math)
✏️ “George brought my grade from 63 to 100. Enough said.” (Honors Algebra II Student)
✏️ “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.”
✏️ “I don’t know how we came this far without George. There has been a tremendous improvement in our son’s work. He has the A’s to prove it. George is truly a gem.”
✏️ “Our student’s first week of school vacation has been exciting to say the least! He’s already six chapters into his AP Chemistry book for next fall and because he respects Dr. George very much; he’s enthusiastic about hitting the books. His “A’s” in both Honors Geometry and Honors Chemistry came in the mail yesterday and the smile on his face was priceless! Thank you George!”
✏️ “Thank you so much for all you do for our son, and for us!”
✏️ “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 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.”
✏️ “Every time I see George with my son, I feel very happy and blessed knowing that he is in good hands. My wish is not just for my son to raise the points or grades but also to learn what “study” truly means through Math so that he can apply the concepts and skills across the fields in his lifetime. George is a teacher and mentor who can make my wish come true.”
✏️ “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!”
✏️ “I recently told a professional colleague about the most amazing man, Dr. George. She confessed that her son was bored in math and I shared that our son had admitted the exact same sentiment and that he too didn’t want to approach his math teacher because he would simply receive more homework instead of the progressive math education he was looking for. I told her that Dr. George has come to our house for three years, and every single time he tutors our son he has the same kind, upbeat, prepared approach without fail and that Dr. George is our best resource for MCAS, SAT and test prep hands down. He shows up more than prepared and always with the same sincerity every single time, simply to teach our son in the best way our student can learn. Simply put, we can’t do without Perdocere and our son’s grades are the proof!”
✏️ "George’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.”
✏️ “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 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 quickly and accurately assessed our son’s needs, then put together lesson plans, exercises and study guides geared to address his specific needs. He just came home with his first A.”
✏️ “George has helped my daughter realize that she really could understand math. Her improved test scores inspired her to work harder, not just in math, but also in all her classes. Her confidence and ambition both grew as she realized that she could master a difficult topic. George has the gifts of a good translator and teacher, he listens extremely well and then uses words and descriptions that can help students decipher difficult concepts. George’s approach to learning, studying, and preparing are completely transferable across many subjects.”
✏️ “George has been the best investment we could have made for our son. He has been tutoring him for over two years now and our son has been in honors math ever since. He and George are now in the process of SAT ‘training’, if you will. We just know that his scores will be nothing but impressive. Thank you, George.”
✏️ “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’.”
✏️ “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)
✏️ “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”
✏️ “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.”
✏️ “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.”
✏️ “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.”
✏️ “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.”
✏️ “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 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.”
✏️ “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.”
✏️ “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!’ ”
✏️ “Working with George has been great and I really look at my classes in school in a different way. I know that I can rely on George to go that extra mile to make sure I really understand what I’m learning, and that makes school much more manageable.”
✏️ “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.”
✏️ “George did an excellent job working with our daughter over the past year. He built her confidence and knowledge base so she could execute complex math problems under time pressure. We believe that one of George’s key strengths is his ability to work with strong students in advanced classes to achieve top performance. In addition, our daughter had fun working with George. We will use him in the future.”
✏️ “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 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.”
✏️ “We simply could not do without Dr. George! Our student even requested tutoring over his two week summer vacation to continue to benefit from his one-on-one, personally structured sessions with the wonderful, kind and very smart, Dr. George! Our son’s academic year will begin on a high note as he pushes to remain ahead of the curve in math. A standing ‘O’ is in the highest order for Dr. ‘G’.”
✏️ “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!”
✏️ “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)
✏️ “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 is a good guy. A+ tutor. Great results, my son scored a 730!”
✏️ “George has not just taught me, but he re-wired my brain in a way that allows me to comprehend subjects I haven’t gone over with him. He has given me the tools to understand any math or science problem out there.”
✏️ “The patience, commitment and encouragement of the instructor have helped our son bring his grades up significantly; and as his marks improved, so did his spirits and his confidence.”
✏️ “George is a fun guy who knows his stuff. He is enjoyable to work with and the results are astounding.”
