“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
✏️ “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.”
✏️ “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.”
✏️ “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!”
✏️ “The best tutor we have ever had, and the nicest!”
✏️ “George is by far the best teacher I’ve ever had! The way he teaches and presents the material is unlike anything I’ve come across. I’m not sure why I’ve never witnessed this way of teaching before, because it clearly works! The math really does become clear with George at the reins. When I look at any sort of math problem, I can truly say I understand all the pieces and how they interact. My way of thinking about math has always been a way that has irritated and frustrated my teachers because I don’t always catch on as fast as the other students would. George is able to pick up on this and teach the math at any angle to suite my learning style. I am highly confident that he will do the same for you!”
✏️ “Throughout the SAT math class, George has made all the questions that are considered hard seem so easy. He has also shown me different ways to come up with an answer for each question. This has caused my math grades to improve!”
✏️ “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.”
✏️ “Far more than a brilliant teacher, George’s warm and positive attitude has been truly therapeutic by giving our daughter a new confidence and competence in math.”
✏️ “George is the best teacher I ever had.” (780 Math Level IIC, A in Level 1 Precalculus)
✏️ “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 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.”
✏️ “George is a good guy. A+ tutor. Great results, my son scored a 730!”
✏️ “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.”
✏️ “What a revelation to learn that instead of being bad in math, our daughter just wasn’t being taught in the manner in which she learns best. George identified her individual learning style and the results have been astonishing. He does a superb job of dovetailing his tutoring of math at the high school level with his preparatory course for the math portion of the SAT.”
✏️ “George is the best math tutor imaginable.”
✏️ “George gave me the confidence to believe that I could succeed in exams. He is a very patient teacher and is just the best at explaining difficult concepts. He makes it easy to concentrate and focus on the key parts of the course content.”
✏️ “Dr. George is one smart man! Not only has he brought our son’s math and science grades up to A’s, but he also shows our son the possibilities for his future! While some students crave the latest video games our son craves knowledge that Dr. George unfolds for him every week in a kind and consistent manner. Our student is looking forward to taking the SAT’s because Dr. George is preparing him fully! We know you can’t ‘cram’ for these tests and we feel privileged to have Dr. George teach our son now while he has ample time to prepare fully!”
✏️ “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.”
✏️ “I got a perfect PSAT math score, thank you!”
✏️ “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 started working with our teen last year after being recommended (highly) from a friend. We were impressed immediately – he connected with our son and tuned into his style of learning from the very first session. Not only has our son improved in math, but the PSAT/SAT prep work he is doing now is sure to reap benefits during this coming year. We just wish we had found George years ago!” (700 SAT Math)
✏️ “George is a fun guy who knows his stuff. He is enjoyable to work with and the results are astounding.”
✏️ “George is the best math teacher I have ever had and for the first time in my life I can now say I feel confident in math. I get it! He is so organized. He challenged me to really push the limit and had confidence in me that I could achieve the goals we set together. I wasn’t to sure but with his methods, encouragement and great teaching I did it and feel great about it too. I did greats on my SATs, my math grade is an A and I now will enter the honors level. I wish I had met George earlier. Thanks George.”
✏️ “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.”
✏️ “George has been more than a math tutor for me. He has not only taught me everything I need to know to succeed in math class and on the SAT, he has also become a best friend during the process.”
✏️ “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.”
✏️ “We first looked for a tutor when it became clear that our son did not understand the material in his honors pre-calculus class and was moving from a passing grade to a failing grade as the material became more difficult. We asked George to work with our son. He first worked to stop the immediate problem by working with him on a quiz by quiz basis. As this crisis diminished, he has devised a longer-range plan to bring our son up to the point where he can achieve on his own. George has a rare skill of understanding the material and being able to communicate it in a way that our son could understand. Thanks to George, our son has renewed his confidence and improved his grades enough that he is now on a course to respectfully pass his honors pre-calculus course.”
✏️ “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.”
✏️ “He is very patient and explains complex terms in simple English. He also works hard to keep a smile on your face even when things are difficult.”
✏️ “George taught me the difference between wisdom and knowledge, and George is by far the most experienced and intelligent teacher I have had the pleasure of working with.” (800 Math SAT, 800 SAT Math IIC, 36 ACT)
✏️ “Thank you for all that you do for our son!”
✏️ “I love working with George. He is so intelligent and can explain concepts in so many ways that it is easy for me to understand. What I appreciated the most is how supportive he is. He makes me feel that I can achieve anything!”
✏️ “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.”
✏️ “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)
✏️ “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.”
✏️ “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 working math-a-magic with my daughter! She so enjoys her sessions that she not only laughs with interest as she progresses, but she also giggles in surprise as she learns from her mistakes. She is advancing at a tremendous rate; and this from a child who never before knew math without tears.”
✏️ “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.”
✏️ “George has been an amazing tutor who has helped me accomplish my goals in both school and the SATs. He has the unique ability to teach one concept in many ways, which is rare to find among teachers. Overall, it has been a very positive experience.”
✏️ “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!’ ”
✏️ “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.”
✏️ “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’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.”
✏️ “Not only has George quickly and effectively helped my daughter to significantly raise her ACT math scores but he has boosted her confidence ten fold!”
✏️ “I cannot express my gratitude to George who is devoted to my son’s education. George ensures that the time spent is productive. My son’s experience has been excellent, and the results were exceptional. George is not only the best math teacher for my son but also a mentor who helps him open new doors for the future.”
✏️ “George was a great teacher to have while I was preparing for the SAT. He really took the time to get to know what my strengths and weaknesses were, how I worked under test conditions, how I approached problems, etc. Just after one session he knew how to guide me and helped me set realistic but challenging goals. George made sure that I had clear and basic foundations for solving problems and then worked with me step by step until everything was clear and I was confident about how to handle similar problems. His teaching not only helped me through the SAT but has also followed through into my everyday school work. His enthusiasm and dedication is really meaningful and one thing for sure is that George knows how to teach.” (280 point SAT math increase)
✏️ “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.”
✏️ “I can always rely on George to help me understand a particularly challenging concept in math.”
✏️ “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 has been an inspiration to our son! He now has the confidence that he can actually understand and be successful in math.”
