“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
✏️ “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 brought my grade from 63 to 100. Enough said.” (Honors Algebra II Student)
✏️ “Math had never been my strong suit, but in only a short time tutoring with George, my math SAT score increased by more math 100 points. More importantly, I find myself realizing that math can, indeed, be fun and interesting. George’s teaching style is engaging and his enthusiasm for even the most mundane math is contagious, spurring me to apply myself to my studies. George delineates even the most impenetrable concepts with patience and clarity. I greatly appreciate the deeper understanding of math that George has imparted to me, and I look forward to the future!” (780 SAT Math)
✏️ “We are absolutely thrilled with what George has done with our son. He has instilled a sense of confidence, made him realize that he can excel academically and allowed him to set his sights on things that he never thought he could achieve. George is incredibly knowledgeable, extremely approachable and a fantastic teacher. He has gone out of his way to make sure that our son is always prepared for his next challenge. George will be part of our family’s academic life for years to come!!”
✏️ “I have always struggled with math, but George has helped me conquer the beast.”
✏️ “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 is a very sound investment for parents seeking to help a struggling student. George genuinely cares about the teaching aspect of education and his concerns are focused on ensuring the student understands each concept thoroughly. He recognizes that while grades are the formal measurement of results, just as important is the student’s confidence level and comfort with the subject matter. As a consequence, our daughter’s grade rose from a C- to an A- in two months, but equally satisfying is seeing her growing confidence in herself and her abilities.”
✏️ “George is a good guy. A+ tutor. Great results, my son scored a 730!”
✏️ “George is an amazing teacher. He is the best tutor a parent can hire to help their child succeed in both mathematics and science. George is true to his thorough teaching; he goes beyond the knowledge taught at school to explain concepts. Having George as a tutor has been invaluable to me throughout high school. Whether you seek to improve grades in school, or simply to study advanced topics, no one can do a better job at helping you than George. George taught me basic calculus the summer before my AP Physics B course, which allowed me to view physics in a whole different perspective than the rest of my classmates, and has led me to decide to major in Biophysics next fall. And as I sit in my AP Calculus class this year, I can only smile and think, ‘George has taught me well.’ ”
✏️ “The best tutor we have ever had, and the nicest!”
✏️ “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)
✏️ “George has worked with our boy for the past eighteen months. The improvement in his grades, as well as his overall approach to school work has been amazing. His own words sum it up ‘George taught me a new way of thinking. He retrained my brain to think the way he does’.”
✏️ “The children never complain that George is boring or off topic or that he is a waste of their time, and they would if they thought that. Almost any other teacher or tutor did elicit those comments sooner or later from the same children. They tell us that even though George makes them work hard, the effort is worthwhile and that they are being exposed to something uniquely valuable and not duplicative of school work.”
✏️ “George has tutored my daughter in Pre-Calculus and Math SAT prep for the past year. George has very impressive credentials, but even more impressive is the math rapport he has with my daughter. Clearly, George understands math at a depth and breadth that few of us do. But his ability to teach it and be a successful tutor is really what impresses me the most. He is a natural teacher. He can see when a student isn’t “getting it” and he can explain a concept in a variety of different ways instead of merely repeating the same explanation again and again. And finally, George truly seems to love his job. He appears to be genuinely happy when my daughter accomplishes her goals or nails down a difficult concept. My daughter feels her time with George is always productive as he’s always prepared for their session.”
✏️ “George has been working with our son for more than a year now. We can’t say enough for George’s abilities to teach – whether it be physics, mathematics or SAT prep, George ensures that our son has a comprehensive understanding of the materials. He challenges him to think through problems and apply concepts. George also has a way of making learning and academic achievement something that our son is proud of. He has instilled in him a level of confidence in his academic abilities that would not have existed absent George. Anyone wanting a truly dedicated teacher and genuinely nice guy to work with their son or daughter should always look to George first.”
✏️ “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 expanded my interest and ability in math while working with him this past school year. I have really learned a lot as well as a positive and reliable approach to math. It has been a great experience working with George and I am looking forward to working with him to prep for the SAT’s.” (790 SAT Math)
✏️ “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.”
✏️ “After the first couple of math tests at the beginning of my sophomore year of high school, I knew I needed help. After just a couple of sessions with George I immediately became a standout in the classroom, consistently on the verge of a perfect test. George rebuilt the foundation of my mathematical skills, allowing me to see the ‘big’ picture and to intertwine new ideas with old concepts. His ability to aid me in understanding the undercurrents of what my teacher was lecturing on in school allowed me to excel in the classroom. I have had George as a tutor for three years and he has inspired a sense of appreciation in the workings of Mathematics that I am now considering pursuing the subject as a major in college.”
✏️ “Before I started working with George, I lacked the confidence and tools to complete my math year with a strong ending. After just three meetings with him I began to receive A’s rather than C’s. Not only does George teach with passion, but he also tailors his explanations and the presentation of the material to fit my specific needs. His commitment to my learning is exemplified by willingness and ability to describe the real content and meaning of the work rather than simply relying on the memorization of formulas. Working with George has made me believe that the key to successful learning is dependent on a great teacher – and George is a great teacher.”
✏️ “Thank you so much for all you do for our son, and for us!”
✏️ “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 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.”
✏️ "George knows exactly how to prepare you for standardized tests. He provides you with more than enough preparation to succeed. I worked with George for about eighteen months, and I got an 800 on the math SAT, a 36 on the ACT math, and a 99% on my final exam in honors pre-calculus. Only George can bring the perfectionist out of you.”
✏️ “I am very impressed and happy with George as a tutor for my daughter. With his extensive knowledge, he can instruct her in both math and science, both for the classroom and SAT prep. I think he is very patient as he works with the student and is able to quickly discover how best to work with them.”
✏️ “George 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.”
✏️ “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 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.”
✏️ “George gave our son the tools and confidence to achieve results above and beyond what he believed was possible. He is a terrific teacher.” (college student parents)
✏️ “Beginning with the very first session, my school work became much easier. George helps me understand math in a way I never did before.”
✏️ “I have been extremely happy with George tutoring my son for honors Geometry in his first year of high school. My son had a difficult transition to the rigor and demands of high school for which he was not prepared coming from a quite weak math background from middle school. George became his tutor in the most complete sense of tutoring, meaning that he did not only teach my son all the concepts in a way he could understand and without memorization but also gave him a method to study and trained him to think and solve problems. This allowed my son to regain his confidence and to learn how to study not just math but other subjects as well. George’s dedication, for all aspects that could benefit my son impressed me from the beginning. He knew from the start how to engage him, how to make him confront difficulty in a rational way, something that requires besides a deep understanding of the technical concepts a strong educational knowledge and experience. I will recommend George without hesitation to anyone that wants to truly understand math and succeed in academics.”
✏️ “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.”
✏️ “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!”
✏️ “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 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 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 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.”
✏️ “You have set the ‘gold standard’ that I don’t think anyone else can approach.”
✏️ “George is a great tutor. His math knowledge and his ability to teach it in such a way that my son understood it was amazing. My son improved his Math SAT score by almost 100 points. I highly recommend George both as a tutor and as a person. He made a huge impression on my son. Thank you so much.”
✏️ “During junior year, Perdocere helped me prepare for several standardized tests in both math and science. Perdocere was distinctly more effective than the other tutoring organizations I tried. With Perdocere’s help, I earned a 740 on the math portion of the SAT I, a 760 on the SAT II Physics, and a 5 on the AP Physics B exam. George helped focus my hard work and succeed where I had to.”
✏️ “We knew our son was brighter than his grades were showing. George did wonders, going back to basics and making sure he really understood the underlying concepts for both math and chemistry. His grades have improved, his confidence is back, and he recently hit the 700 mark on his math SAT. Now, if only we could send George to college with him...”
✏️ “Working with George is fun. Before I started working with him I always hated going to math but not anymore. I enjoy math. I don’t want it to end. He is doing an amazing job getting me up to par with my grade. He is the best math teacher I have ever had and the sooner you start working with him the better. If you put in the time he will be able to catch you up and get you in front of your whole school. If you don’t work with him it’s your loss.”
✏️ “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.”
✏️ “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!’ ”
✏️ “George is hands down the best tutor we have ever encountered. He understands that students cannot excel in math unless their knowledge is built on a solid foundation. In tutoring my daughter, he returned to basics, discovering areas of weakness and explaining misunderstood concepts. A comment that my daughter made in passing, “I can ask George any question about math, and he can answer so that I can understand.” While he is conservative in making promises about outcomes, he committed himself 110% to ensure as successful an outcome for my daughter as possible. Our first goal was to achieve strong performance on the math SAT, where he approached the subject matter in a methodical, knowledgeable way, she scored a 780 on her first math SAT. With that successful experience under our belt, we then wanted to ensure strong classroom performance for the fourth quarter of her junior year. My daughter was receiving B+’s in her honors pre-calculus class (and averaging B’s on her tests and quizzes), but the subject matter became increasingly more challenging, and she was faltering in her ability to grasp concepts, particularly with respect to the topic of probability. George worked week in and week out to review the various chapters with my daughter, preparing her for tests, encouraging her after a difficult test. She received a B+ for her fourth quarter work, which I believe would have been significantly lower without George’s help. In order for my daughter to achieve an A- for the year, she needed a 95% on her final exam. George worked tirelessly to help her achieve this goal, but again was cautious in guaranteeing any results. My daughter and I were thrilled to see her report card a month after her final, with an A marked clearly for her final exam! We look forward to George helping us negotiate BC calculus as well as the Math Subject II test in the fall!”
✏️ “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, over the past few months, we have been amazed at the progress you have made with our daughter. While the improvement in her ‘trial run’ SAT scores has been significant, of equal note has been the change in the way she now approaches math problems: she thinks differently! Your ability to explain the processes behind the formulae, and the way that you teach to each student’s strengths, is a thing of beauty… For a 17 year old to stay focused on math over and entire summer is a testament to your ability to engage someone’s imagination and intellect. I am grateful for all of the encouragement and focus you have provided. And, while I look forward to much improved success in our daughter’s upcoming SAT scores as a direct outcome of your work, I also appreciate the confidence you have helped her build over the summer. She is clearly far more prepared for the tests ahead than she was in early June. My only regret? We didn’t do this sooner.”
✏️ “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!”
✏️ “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 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.”
