Parent and Student Testimonials

✏️ “We can’t say enough about how good a teacher George has been throughout the years. We feel that our children are well grounded in fundamentals and have the confidence to take on any academic challenge in the future. George is devoted to his craft and a truly unique academic tutor.”

✏️ “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!!”

✏️ “We have had many tutors in the past and George by comparison is extraordinary. George’s weekly sessions helped my high school boys achieve never before A’s in their math classes. My husband and I were so impressed with his intelligence, dedication and patience. These qualities allowed my boys to truly understand SAT test taking and math strategies. We highly recommend George!”

✏️ “George is the best math tutor our daughter has ever had. He has given her the critical skills to understand, encode and recall mathematic principles to achieve her best possible classroom scores.”

✏️ “George enthusiastically provides the most positive atmosphere for thorough understanding, solid development and concrete achievement in mathematics. He teaches in the spirit of a love for learning and instills an intrinsic desire for continued learning and understanding. George holds our daughter to a higher standard of achievement which she reaches for with great pride in accomplishment.”

✏️ “George has been active in the academic lives of our two sons for the last four years. Each learns in a very different manner but, amazingly, George has been able to unlock both of their intellectual personalities. He consistently gets to the whys and wherefores of mathematics and is tireless in ensuring that his students’ math foundations are strong. He motivated our oldest son so much that he now is majoring in math in college. He has guided our second son to the top of his math class and now beginning to guide his SAT studies. George proved that an ‘800’ was possible; perhaps he can make it two in a row. George is always willing to go the extra yard to help his students and takes a sincere interest in their success. George has a gift that few have – a brilliant intellect coupled with an intuitive ability to teach. I count on him as part of our family because of the time and effort he has devoted to the education of our children.”

✏️ “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 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.”

✏️ “Thanks to George I not only feel more confident in math, but I also feel like I am receiving a strong education from someone who is dedicated to helping people learn. Every lesson is based on what I need, and he never disappoints. His approach to math is both fun and engaging. He helps me get the results I want without substituting memorization for learning.”

✏️ “George made it possible for my son to go to the best college for him. George is the best teacher and mentor my son could have. We cannot thank him enough. I cannot wait to see my other children grow as learners with knowledge and strategies taught by George.”

✏️ “When most people think of a ‘tutor’ they think of an individual that helps with a particular subject area, usually through studying or practice. When I think of George I find the standard definitions of ‘tutor’ no longer apply. Although George is great at ‘traditional’ tutoring he has a skill set that enables him to do so much more. His ability to teach material in a way that is easily comprehensible makes learning material unbelievably easy. I started with George in the 8th grade when my math grades were not so great. He took my grades in my 8th grade algebra course and turned C’s into A’s. Five years later I graduated high school with an 800 in my math SAT, a 790 in my math SAT IIC, and an A- in AP Calculus BC, the most difficult math class ever offered by my high school. George truly is the best, from science, math, and in my personal case, computer programming. George has the esoteric knowledge and raw intellect necessary to come through on his business name and `instruct thoroughly’.”

✏️ “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)

✏️ “Math has never been my forte – even though George tells me I’m good at it every time I meet with him. Which in a way is true – because when George is teaching me I am good at math. Instead of only showing me how something works, he’ll explain why it works, which is exactly the teaching style I need. The difference in style, and therefore effectiveness, between George and my teachers at school is so vast that there’s a distinct possibility I would be failing math without him.”

✏️ “Our son was diagnosed with lymphoma during his freshman year and has been out of school for a year and a half. In addition to feeling sick from all of the chemo treatments, he was feeling hopeless that he would ever be able to catch up with his schoolwork. What he wanted the most was to catch up in math – Algebra II. George was the answer. For almost a year now George has been teaching him in our home for 4-6 hours a week. Not only is he catching up but he is also maintaining an A average and he will be able to enter his junior year this fall feeling completely confident in his math knowledge. We are so grateful to George for that. Although he has a long way to go catching up in all his other subjects and he still has another six months on chemo treatment, he is ready to get back to his life as a normal high school student. Couldn’t have done it without George! Thank you for your dedication to our son – mathematically and emotionally!!”
“George is a great tutor and a very nice person to talk to. I would recommend him for anyone.”

✏️ “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!!!”

✏️ “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 has made such a big difference for our child – academically and personally.”

✏️ “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.”

✏️ “This year, I am taking the most rigorous math course my school has to offer, AP Calculus BC. BC calc is extremely fast paced because of the AP test in May. Some of the topics are only covered for a fraction of a class; however, with George’s help, I am a month or two in front of the class. Because of the two month lead, George is able to show me more advanced topics that will never be covered in BC calc. The way that George teaches calculus incorporates everything that was previously learned in calc while still covering a lot of material extremely thoroughly. In class, I have done well on all of my tests. George has allowed me to obtain an understanding of calculus which seems impossible to get from the class alone. I am very thankful that I have George guiding me through BC calc.”

✏️ “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.”

✏️ “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.”

✏️ “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.”

✏️ “Before I began working with George, I was getting good grades in math but much of the time I didn’t really understand what I was doing or why I was doing it. After my first session with George, I could tell he was a different kind of teacher. He really explained the concepts instead of just teaching me steps that I had to memorize. George always makes sure that I completely understand what I am working on before we move on to a new concept. I look forward to my sessions with George. George makes the sessions fun, interesting, and challenges me to think in ways that I haven’t been taught in school. George also happens to be funny and kind and I feel he really cares about me as a student.” (96% Final Math Assessment)

✏️ “We would heap praises, but facts speak better. With a ‘C’ in 8th grade math, and teachers happy with ‘the C’, which translates to just passing 8th grade MCAS at the cut-off grade, we looked to George to teach our child. The weekly two-hour session is productive and fun for our child! We would never have imagined our child sitting for two hours on High School Algebra – but it happens every week – only with George. George finds a way to teach and convey concepts in math – overcoming our child’s learning disabilities. Our child brought home a B+ in Algebra, and in one Algebra quiz, got the first time ever 100%. Our child has gained confidence which beats the frustration and ‘I hate math’ during 8th grade.”

✏️ “In preparation for high school, I asked George to find and patch the holes that we knew existed in my daughter’s math knowledge. Although my daughter has been an A student in math, it was apparent to me that she was getting by without really understanding the logic and meaning behind what she was doing in math. Because of this mechanics, memorization based approach to math, she found the subject to be her least favorite. George promised that he would find the holes in her knowledge and would then equip her with a deeper, more functional way of attacking math problems. In only a few sessions, the change in my daughter was evident. Her test grades improved, but most importantly, so did her confidence and creativity in finding solutions to math problems. My daughter happily sits through her sessions with George and is 100% engaged and happy. George is brilliant, thoughtful and kind and really understands how to work with kids. I feel that George is fully invested in my daughter’s success. I wish that all teachers were as wonderful and George!”

✏️ “I have always struggled with math, but George has helped me conquer the beast.”

✏️ “The SAT Subject Test for Math Level IIC is not an easy test. One must completely understand the topics that are covered to complete the problems, and one must have precision and speed to score high on the test. With George’s help, I was able to get high scores on many of the practice tests which reflected my real score. George has taught me the best ways to approach each problem; I can now solve each question quickly while understanding the math behind each question completely. I am very thankful that I was able to meet George, for his teachings and support allowed me to success on the SAT Math Level IIC test.” (780 SAT Math Level IIC)

✏️ “I’ve always struggled with pre-calculus and calculus. My teachers never taught the theory behind the problems, or how it was connected to the big picture. George makes it his mission to make sure you thoroughly understand the concepts of the subject.” (college calculus student)

✏️ “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!”

✏️ “George has an amazing amount of patience and challenges me at every turn. The truth is in the results! I am a more confident learner and that carries over to my other courses, as well. I got an A in my Honors Algebra class and look forward to working with George as I prepare for the PSAT/SAT/ACT tests.”

✏️ “George made a huge difference in how our son approached math problem solving, as well as in how to take the SAT. George quickly identified fundamental mathematic deficiencies and provided the education required so that these principles can now be applied in any setting, not just in taking the SAT. We look forward to working with George again next year. Thanks George from all of us!!!”

✏️ “George is a great man! In my time working with him I have learned VERY much! I believe that George’s help is of the utmost benefit for anyone who wishes to enrich themselves and to be successful in math!” (800 Math SAT)

✏️ “George, you are perpetually a star! Thanks so much for all your help with our son. We are so very appreciative.”

✏️ “During my sophomore year in high school, before I began tutoring with George, I worried constantly about the effect my math grade would have on my grade point average. George started teaching me during the beginning of my junior year, and now, having graduated from high school, I can look back and say that George’s superb skills as a tutor led me from getting B’s in Algebra II to A’s in BC Calculus. Thanks to George, math stopped being a constant source of worry for me and became a course that helped me maintain my GPA. I studied under George for two years, and my attitude towards mathematics changed immensely during that time. George’s patience and creativity make him an ideal tutor for both struggling students and those who wish to broaden their understanding of mathematical concepts.” (770 SAT Math, 770 SAT Math IIC)

✏️ “George knows his stuff! He’s helped me go from an average student to an above average student in my Advanced Algebra class. He has improved my study habits and mathematical confidence.”

✏️ “George’s results have been spectacular in terms of overall grasp of subjects and preparation for specific exams. He is the cause of one or more of our children getting perfect or nearly perfect scores on SAT or AP tests where, in some instances, the effort was there but, prior to George, not much interest or aptitude a specific subject. He visibly changes good students into superlative students.”

✏️ “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 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.”

✏️ “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 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.”

✏️ “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 enabled me to get an 800 on the math SAT and, for most parents, that may be all they need in a tutor. However, George isn’t just an effective tutor, he actually cares about the student. When I first started with George math was my least favorite subject, mainly because I just didn’t ‘get it.’ However, now, math is my strongest subject and I adore the class. George allowed me to not just ‘get by’ in my class, but to understand the material, and, through understanding excel. I can’t recommend George enough on both a professional and personal level.” (800 SAT Math, 36 ACT Math)

✏️ “Perdocere Math Tutoring with Dr. George was the best decision we ever made for our son. George has not only given our son the knowledge and understanding of math, but the confidence to master it. He has given him the skills and confidence he needs to truly be a success. We can thank him for not only the math skills learned but also his advice in SAT management and preparedness and in interview techniques. We give Dr. George a perfect score!”

✏️ “Although I’ve only been with George for a short while, the most important thing I have discovered about him is that his teaching style is highly effective. Not only does he teach you how to do something, he teaches you why it is done that way. He is able to show you how basic concepts can be used to solve highly complex problems. Now, I am able to see the building blocks of each individual problem, and, from there, I am able to find the solution. He is totally approachable and will help you with anything. I know on countless occasions he has also given me advice that I find applicable to my physics homework. He truly does instruct his students very thoroughly, and if you are unsure of something, he will go over it as many times as you need. Because of him, I feel thoroughly prepared to take my SAT exam.” (700 SAT Math)

✏️ “It is with both pleasure and sadness that I write this testimonial for George who has tutored my three children over the last five years in a wide range of subjects (math, pre-calculus, chemistry, physics, biology, computer science, and a little engineering on occasion). George has been an extraordinary resource and has become an honorary family member and a dear friend to me and all my children. He has seen my children through quizzes and tests, helped with tricky homework assignments, and led them to superlative performances on their SATs, APs and ACTs. George has been a terrific mentor as well as a tutor, giving advice on school, the college application process, and the like. George keeps up to date with all assignments posted by the school and helps even disorganized kids get organized. He is terrific at reminding the kids of deadlines for projects, assignments, quizzes and standardized tests. He has always made time in his busy schedule for extra sessions when a big test or project is due, he explains why and how rather than tell a student just to apply the formula, he adjusts his method and style of tutoring to each individual child, he is reliable and efficient and always pleasant, and his range of subject matter knowledge is superb. I honestly believe that George’s tutoring has had a big and most positive impact on my children in many ways. On the most obvious level, he truly did help boost their test scores and probably did impact the level of college to which they were admitted. Beyond that, however, he really gave them a greater appreciation and understanding of subject matters that they were not as comfortable with, and gave them the tools to help them think, analyze and solve. These are tools that they will carry with them and use all their lives, whether they ever take another math course or not. That is what a real tutor does not just get you through the next exam. And even further, George honestly cares about his students not just their performance but also their minds, their interests, and their character. Whenever my two oldest are home from college, they are delighted to see George again, and I know that my youngest will miss George when he starts college this year, as will I. George has been a big part of our lives. We are better of for the experience in many, many ways. Thank you, George.”

✏️ “Our daughter would have never gotten accepted to the highly selective college she now attends without George. Meaning she would have missed the opportunity to go to the school that’s turned out to be perfect for her. We thank our lucky stars for George every single day.”

✏️ “George is a great SAT Math tutor. His thorough knowledge of every part of the test definitely helped me to understand how to take the test in a better and more efficient manner. We tackled each problem as it came and not only solved it but broke down each component of the question so that we could easily tackle a harder version of the same problem down the road. In just three sessions of preparation with George my test scores increases by sixty points and branched into the 700 range. I believe that George’s attention to every detail of the test is what sets him apart from other tutors I tried and is what allowed me to do so well.”

✏️ “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.”

✏️ “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.”
