“I have known George for decades. He has a very clear and dramatic effect enabling students to think and rise to their full potential. George’s influence on so many lives has had significant impact, and I greatly admire him for doing this.”

Parent and Student Testimonials
✏️ “George is the best 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.”
✏️ “After reviewing the yellow insert in the newspaper, I made a note to myself: Call Perdocere? I wondered: What does Perdocere mean? After my daughter’s ACT math results, I felt it was important to take action, so yes I did call Perdocere and spoke with George. After listening to our story, George met with my daughter to begin immediate math tutoring. We had limited time, six months, to accomplish a lot of learning in order to achieve a more successful math test score. Equally important, my daughter was to improve on her math for success when at college. George is a brilliant and enthusiastic teacher. He shared his plan with us and we quickly moved ahead. He had my daughter take both the SAT and ACT practice tests to see which would be best for her. He watched her to see how she worked. He prevailed upon our busy schedule for intense tutoring. George expects a lot from his student, but he gives much in return. For my daughter, she learned that math from him, and he instilled confidence. For me, he kept me in the loop and patiently worked with our schedule. At the six month point my daughter retook the test with George’s best wishes (and his calculator as her calculator shut down days before the test), and she exceeded her goal. Perdocere means to instruct thoroughly, Perdocere is George! Thank you!”
✏️ “I recently told a professional colleague about the most amazing man, Dr. George. She confessed that her son was bored in math and I shared that our son had admitted the exact same sentiment and that he too didn’t want to approach his math teacher because he would simply receive more homework instead of the progressive math education he was looking for. I told her that Dr. George has come to our house for three years, and every single time he tutors our son he has the same kind, upbeat, prepared approach without fail and that Dr. George is our best resource for MCAS, SAT and test prep hands down. He shows up more than prepared and always with the same sincerity every single time, simply to teach our son in the best way our student can learn. Simply put, we can’t do without Perdocere and our son’s grades are the proof!”
✏️ “George has been an inspiration to our son! He now has the confidence that he can actually understand and be successful in math.”
✏️ “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 has been working with my son since June. When I called George we had a great conversation and I explained the math issue my son was having. He understood the issues and had a solution and a game plan to attack the problem. Since working with George my son’s math comprehension and retention has improved. But more importantly, my son looks forward to working with George weekly and requires no prompting to be prepared for tutoring. He uses positive reinforcement to engage my son. Currently, George is working with my son on SAT preparation. The strategies put in place will allow my son to do well on the SAT exam.”
✏️ “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.”
✏️ “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.”
✏️ “In preparing for the SAT, George helped me dissect each problem into its basic parts. There is no better preparation for the Math SAT than with George.”
✏️ “Since I took the hardest math class at my school this year, I was nervous about my math grade. Thanks to George, on my last test I got the first 100% I’ve gotten since freshman year! My math has greatly improved since I started working with George, and for the first time I find that I am genuinely interested in math. I cannot recommend George highly enough!”
✏️ “George started late in the year tutoring our son, in a very short time his grades were up. His scores on the SAT and AP exams were exceptional. However what is more important is that George is coaching him on how to study and not only tutoring him in a subject. He is helping him choose his courses, as well as guiding him through his high school years. The look on both their eyes while studying is one of pure joy. George is an exceptional tutor as well as a dear friend.”
✏️ “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.”
✏️ “George has helped me ace my honors precalculus class and, by doing so, he has rekindled my appreciation for math as well as my confidence.”
✏️ “George has worked with my children on test prep for the SAT, ACT, AP exams, and the SAT subject matter tests. My two oldest — for whom math is their worst subject — scored a 740 and a 790 on the SAT math section. My youngest just scored an 800! I, and they, attribute the high scores to their work with George. He not only helps them with the substantive skills needed for success, but also with the practical hints that come in so handy on standardized tests. He works through many practice exams and works to educate them about their particular strengths and weaknesses so that the right emphasis in studying can be made. All three of my children report that they feel that working with George has made a big difference in their school performance and test scores.”
✏️ “George is a wonderful tutor that has made a significant impact on my daughters learning. He discovered her weaknesses and has worked tirelessly with her to fill in the gaps in her learning and prepare her for the SAT. He cares deeply about his students and communicates weekly with me on her progress. George is like no other!!”
✏️ “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!”
✏️ “Anyone who says that the SAT Mathematics section cannot be taught has not met George. After scoring a low 600 on my first practice exam, George stepped me through the process of learning how to take the test as well as the mathematical concepts behind it. After several months of training, George helped me to receive a perfect 800 on the Math section. And if that wasn’t enough, he also guided me through the SAT Mathematics IIC Subject Test, which, with his aid, I scored another perfect 800. Thanks to George, I was able to conquer the SAT’s.”
✏️ “I could tell, my son really liked you and already is getting huge benefits from working with you. Thank you, thank you, thank you!”
✏️ “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.”
✏️ “I wish we had found George sooner! He has done a wonderful job of not only teaching the current year’s math, but also of going back and filling in the missing pieces of our son’s mathematical foundation. He has helped him in the sciences, and as we move into SATs, I expect to see his positive influence there as well. Our son in a more confident student because of George. However, I think George’s greatest strength may be sensing what learning style fits our son and being able to adapt on a given day to what he needs, both emotionally and scholastically.”
✏️ “George has helped me tremendously. I get a solid A in math since George has started tutoring me. I also am doing much better on my SAT’s. Before George I couldn’t even get passed the first question. George is a great tutor.”
✏️ “George has been tutoring me since the eighth grade. Ever since we started working together, my grades have increased dramatically in math class. I like the approach George takes to tutoring. Unlike the teachers at school, George will teach you thoroughly, no matter how complicated the task. In eighth grade I was barely passing my math class. George has shown me that I am capable of getting A’s; it just depends on how well you’re taught the material. The following year I got a 93% on my Algebra I final. George’s charismatic attitude is a huge part of what makes him so special. Math class in school is generally like going to the dentist. It isn’t remotely pleasant, but you’ve got to do it. George somehow makes the experience an absolute pleasure. I look forward to our meetings. I’m confident that George has the intelligence, experience, and the overall talent to teach most anyone with excellent results. Believe it or not, not everyone is up to the task of teaching math. I can say whole-heartedly that I believe George is, and then some.”
✏️ “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.”
✏️ “Initially we brought to George tutor our daughter in AP physics. He ended up tutoring her in both Physics and Pre-Calculus. He also provided help in preparing for SAT and ACT exams. We were very pleased by his dedication as a teacher. He goes above and beyond the average tutor by following up on exam results and checking in the night before to make sure she was ready or to answer any last minute questions. My daughter truly believes she would not have made it through those classes without George’s help.”
✏️ “I don’t know how we came this far without George. There has been a tremendous improvement in our son’s work. He has the A’s to prove it. George is truly a gem.”
✏️ “Our 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 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)
✏️ “You helped our son have a dream come true, thank you.”
✏️ “Thank you so much for all you do for our son, and for us!”
✏️ “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 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.’ ”
✏️ “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!!”
✏️ “Believe it. It’s true. Before George started tutoring our daughter, I read every single one of the testimonials on this website. It was clear the students and families were overwhelmingly pleased, but could he teach our child? It took mere minutes before I heard our daughter say, "Oh I get it! That’s easy" At that very moment, two things happened. I quietly breathed a sigh of relief because I knew we had found the perfect tutor, and our daughter began to believe in herself. The big question in our house a few months ago was “What are we going to do about math?” Now we’re looking far ahead and wondering to ourselves, “What will she do with math?” ”
✏️ “He has genuine passion for teaching in its most basic sense. His subject knowledge and teaching style encourages our child’s participation in a planned roadmap for success.”
✏️ “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.”
✏️ “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!”
✏️ “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.”
✏️ “You have set the ‘gold standard’ that I don’t think anyone else can approach.”
✏️ “Who would have thought that my son would become a curve breaker! Through the years George has instilled a great store of fundamental mathematical knowledge. On this foundation our son was able to grab Calculus by the horns and completely master it.”
✏️ “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)
✏️ “I’m proud of my accomplishments since he has worked with me.”
✏️ “George has a superior understanding of higher mathematics and science which combined with his ability to communicate abstract subject matter to the kids is like no other teacher we have known. As for results, George has guided our son from mediocre to excelling. His high MCAS scores are a measure of his dramatic improvement. His SAT practice scores steadily climbed to impressive levels, and he gained 240 points on the SAT math. George mentors and provides guidance with understanding to his students. Our son has developed a strong sense of purpose to do well which we attribute in part, to his mentoring. We’ve had George tutor both our sons. George is the best gift you can ever give to your son or daughter.”
✏️ “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.”
✏️ “Our daughter has always struggled with math, especially on standardized tests. Always a good student and hard working, she was always disappointed with her test scores. By working with George, she has grown in her understanding and grasp of the subject. My wife and I are encouraged to see her renewed energetic interest in achieving in math which for too long has been so frustrating and intimidating for her. George, thanks for all your help.”
✏️ “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!”
✏️ “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 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.”
✏️ “I have had many math teachers in the past, but I have never had a math teacher like George. George is the best math teacher I have ever had; no other teacher I have ever had can even compare. It seems like my other teachers has a lesson plan and tried to make me adapt with the lesson plan. George builds his lessons around what I am capable of, so each lesson is completely learned to its fullest. He has even helped me catch up after past teachers have brought me down and held me back. I am extremely thankful that I was able to meet and learn from George, and I hope I can continue to learn from him.” (‘A’ in Honors Pre-Calculus)
✏️ "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.”
✏️ “In my junior year in high school I was taking some challenging courses, courses which on my own I would have had trouble handling in combination with SATs and AP exams. However, George helped me manage not only my classes but also my standardized tests. I ended up with solid grades in my math and science classes as well as an 800 in the math portion of the SAT and a 780 in the SAT IIC for math. Without George’s tireless enthusiasm and unstoppable will to help me I don’t know how well I would have done.”
