Parent and Student Testimonials

✏️ “George is like no teacher I’ve ever had. He takes what looks like a hard Math SAT problem and simplifies it so everyone can understand.”

✏️ “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.”

✏️ “George brought my grade from 63 to 100. Enough said.” (Honors Algebra II Student)

✏️ “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.”

✏️ “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 has been more than just a tutor. He is a friend and a mentor for both our children. Perfect SAT and ACT scores were just the beginning. George is still with them in college. His methods and teaching skills are more than what we imagined. The sooner a child starts with George the better his foundations are made solid, and the confidence the student acquires with his help goes beyond math to encompass all the curriculum.” (800 SAT, 36 ACT)

✏️ “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 is a good teacher because – he makes me think the math out, he is always prepared for what I need to learn, thinks of problems to illustrate a math concept on the spot, drills me on what I do not know, makes me tell him how I arrived at the answer, understands me and how I learn, focuses and encourages me, talks to me.”

✏️ “George is a great tutor and is a great person to work with and not only has helped me learn, but also improve the quality of my work and has helped me change my style of doing math into an easier and more comprehensible method.”

✏️ “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!!”

✏️ “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.”

✏️ “As an extraordinary tutor for classroom math in both middle school and high school, we have now asked George to prepare our daughter for math on the college SAT. We have absolute confidence in George to help our daughter achieve her highest possible SAT math score.”

✏️ “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.”

✏️ “Ever since I began my sessions with George, I have significantly improved my mathematical skills and have consistently been able to maintain high test scores. George has restructured my foundation and constantly solidifies key concepts, which help me to take each problem step-by-step and achieve the correct answer while truly learning the material. George not only helps to get the correct answer but also goes far beyond what is asked and works out multiple solutions to the simplest and most difficult problems. George is able to break down problems into manageable pieces unlike any other math teacher I have ever had. I commend George for his knowledge on the subject. I know with George’s help and positive attitude, I am confident that I will do well. Without George both my algebra and chemistry skills would be nothing like they are today. Thanks George and I can’t wait for another successful year!”

✏️ “Thank you for all that you do for our son!”

✏️ “George has been tutoring our son for over two years now, we are very pleased with the results. Our son has a real appreciation for the method in which George teaches, and is confident in his own abilities now to understand and comprehend challenging concepts. With George the lesson is always positive, focused and thoroughly understood. Besides being such a wonderful tutor, mentor, and motivator, George has encouraged our son to excel in other pursuits as well, always looking toward the future. We highly recommend George!”

✏️ “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!”

✏️ “Our son’s entire success this year is because of Dr. George and his smart and savvy Perdocere Math Tutoring! With Dr. Georges innate knowledge of the academic world we feel confident that we are steering our son in the absolute right direction towards his passion for learning, achieving and most importantly to his happy and bright academic future! We will continue to supplement our child’s education with Perdocere Tutoring because Dr. George has given him the confidence we only dreamed he could achieve! Thank you from the bottom of our hearts!”

✏️ “George has been an invaluable asset to me. Ever since I began seeing George five years ago he has been there to help me through whatever material I was struggling with. Whether is was my eighth grade algebra or my senior year AP calculus George has been able to not only teach me the material but to have me understand it as well. George helped me to get the 800 on the Math SAT and was even able to teach me in biology as well. After trying other tutors I can say without any reservation that George is the best out there. George presents the material in a way that is easily accessible and learnable, making sure that each student is able to learn the material in his/her own way. For my part George has both my thanks and respect for all that he has done. I can’t recommend his services enough and urge you, if you want to see real results George is the one to use.”

✏️ “In a word, George is wonderful! Highly experienced in all branches of mathematics, he also is an exceptionally nice person who cares about his students. Along with solving the problems du jour, he has imparted life lessons about setting goals, working hard, and planning for the future. After working with George for six years, my son will graduate high school with an A in Honors Math and head off to be a math major in college. Back in seventh grade, I wasn’t sure how this was all going to play out. I owe a huge thanks to George for all he’s done for my son. I am so glad I made the call.”

✏️ “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.”

✏️ “Over the past three years, George has become the family’s de facto math and science consiliari. He has not only guided our first son to a string of 800’s but instilled in him a sense of academic confidence and curiosity that will serve him well in college. He also started down the academic path with our second son this year – a very different learner than the first – yet he has struck the appropriate chords with him. George is a born teacher. He is enthusiastic about his subjects, explains and teaches in a clear and logical manner, and patiently drives the learning process. We can always count on George and will continue to rely on him in the future.”

✏️ “The best tutor we have ever had, and the nicest!”

✏️ “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 am getting an A in honors pre-calculus. Not only am I understanding the material fully, I find myself thinking outside the curriculum and trying to learn more advanced math. Only George could have taught me this high a level of math, and he is currently preparing me for advanced placement BC calculus. I am 100% confident George will help me conquer that class too.” (800 SAT Math, 800 SAT Math Level 2 Subject Test, 36 ACT Math)

✏️ “I can always rely on George to help me understand a particularly challenging concept in math.”

✏️ “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.”

✏️ “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.”

✏️ “Our middle school son has a broader, deeper understanding of math concepts since working with George. He no longer memorizes formulas without knowing the why’s and how’s of problem solving. George can teach tough math concepts in an understandable way that translates into learning!! The success our son feels in mastering the math is a great boost to his self esteem. He just got an A+ for the year in eighth grade algebra.”

✏️ “I don’t know how I would get through high school without you.”

✏️ "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.”

✏️ “Our middle school son started to have difficulties in mathematics. After working with him, George was able to assess and pinpoint his areas of difficulty. In addition, George had the patience and teaching strategies that worked with our son. Now he enjoys the challenge of math and feels so much better about his abilities. His grades have gone from a C+ to a B+, and now A’s.”

✏️ “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 was flexible and accommodating when my daughter and I found ourselves overscheduled one month before three scheduled SAT-2 examinations. He organized a study program, identified the appropriate tools, and worked out a mutually acceptable schedule on short notice. His thorough understanding of the information and the test process coupled with his kind and cheerful personal style was very effective. The outcomes met our very high expectations, and we look forward to working with him in the future.”

✏️ "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.”

✏️ “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!”

✏️ “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)

✏️ “With SAT’s looming, I hired George to access and fill in the gaps in my son’s math knowledge. My son scored a 550 on his first practice SAT with George, so there were plenty of areas that needed attention! George came up with a comprehensive plan to rebuild my son’s math knowledge from the ground up. George taught my son to look at math through a completely different lens, which enabled him to think creatively as opposed to mechanically when he approached math problems. This strong foundation coupled with a creative approach to problem solving resulted in a 780 on the SAT. George was professional, methodical, and thoughtful during each session, and knew how to motivate and inspire my son. Although the work was hard at times, my son was always happy and grateful to be working with such a brilliant and kind teacher. I only wish all of my son’s math teachers could be as exceptionally qualified and compassionate as George!” (780 SAT Math)

✏️ “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.”

✏️ “You are the best!”

✏️ “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.”

✏️ “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!”

✏️ “As parents, we all know how different our children are – and this certainly translates to learning styles. George has had to adapt to three very different types of learners over that last seven or eight years. He has successfully navigated one child through a string of 800s… brought another near that coveted goal, thus ensuring his place at the college of that child’s choice (thank goodness!!)… and now has the unenviable task of guiding our daughter through the shoals of high school mathematics and preparation for the SAT. All three of our children have enjoyed working with George; he has related to each one on a very personal level and he has adjusted his teaching style to match how they learn. He is always encouraging and has instilled in all of them the ability to ask questions and explore the whys and wherefores rather than just the answers. At the same time, however, George sets the bar high for each one of them and pushes them to achieve. Not only have they and will they be accountable to Mom and Dad – they are also accountable to George – and they seem to be more concerned about the latter rather than the former (which is fine with us). George has an extraordinary gift for teaching and for instilling a love of learning in his students. He is insistent that fundamentals be strong and he works those so that his students are equipped for higher tasks. On child ended up majoring in math in college and is now doing sophisticated quantitative analysis in an investment firm; another is doing a wonderful job navigating econometrics. We can only hope that our last one can achieve this success. With George on our side we think that this can be achieved. We heartily recommend George to all.”

✏️ “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.”

✏️ “George plainly has a mastery of math and science that runs both broad and deep, and he is very, very good at communicating with both students and parents in clear English pitched to their level of scientific understanding, wherever that may be. He clearly cares about his students, and we feel very confident that he is happy to help any way he can.”

✏️ “You helped our son have a dream come true, thank you.”

✏️ “When I began my sessions with George, I was very apprehensive. I didn’t enjoy math and spending two extra hours outside of school was not something that I looked forward to. As the weeks went on, my confidence in my abilities skyrocketed. George quickly defined my problems, and made a long lasting impression on the work I now do. Not only did my scores dramatically increase but so did my school work. I now approach problems differently and find math to be more enjoyable. George is a wonderful teacher and I cannot explain how much he changed my approach to math. If I have any advice, it would be to listen to everything he says. He knows what he is talking about and the next time I walk into a mathematical minefield I know there will be a trap in the dusty corners that I can conquer. Thanks for everything George!”

✏️ “Before working with George, I thought of math as a drudgery. The subject required a lot of work and study, but it seemed to me that no matter how hard I applied myself, I could not affect a change in my grade. Math was a chore and an ugly spot on my report card. After being taught by George, however, that all changed. George takes the time to explain the mechanics behind a formula, never allowing memorization where there is understanding to be had. Under George’s tutelage, I began to see the beauty of mathematics, and as my interest in the subject grew, I found myself considering it less a boring necessity, but a more rewarding challenge. George’s teaching has turned my opinion of math completely on its head, and also yielded pleasant results during the final exam. Although my term grades before meeting George were not fantastic, I was able to score highly enough on my final exam to bring my overall math grade up to an A-. Without George’s careful guidance, this certainly would not have been possible. I cannot recommend his services highly enough – under George, not only my grades, but also my outlook on math changed 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.”

✏️ “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)
