Parent and Student Testimonials
✏️ “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.”
✏️ “It is with both pleasure and sadness that I write this testimonial for George who has tutored my three children over the last five years in a wide range of subjects (math, pre-calculus, chemistry, physics, biology, computer science, and a little engineering on occasion). George has been an extraordinary resource and has become an honorary family member and a dear friend to me and all my children. He has seen my children through quizzes and tests, helped with tricky homework assignments, and led them to superlative performances on their SATs, APs and ACTs. George has been a terrific mentor as well as a tutor, giving advice on school, the college application process, and the like. George keeps up to date with all assignments posted by the school and helps even disorganized kids get organized. He is terrific at reminding the kids of deadlines for projects, assignments, quizzes and standardized tests. He has always made time in his busy schedule for extra sessions when a big test or project is due, he explains why and how rather than tell a student just to apply the formula, he adjusts his method and style of tutoring to each individual child, he is reliable and efficient and always pleasant, and his range of subject matter knowledge is superb. I honestly believe that George’s tutoring has had a big and most positive impact on my children in many ways. On the most obvious level, he truly did help boost their test scores and probably did impact the level of college to which they were admitted. Beyond that, however, he really gave them a greater appreciation and understanding of subject matters that they were not as comfortable with, and gave them the tools to help them think, analyze and solve. These are tools that they will carry with them and use all their lives, whether they ever take another math course or not. That is what a real tutor does not just get you through the next exam. And even further, George honestly cares about his students not just their performance but also their minds, their interests, and their character. Whenever my two oldest are home from college, they are delighted to see George again, and I know that my youngest will miss George when he starts college this year, as will I. George has been a big part of our lives. We are better of for the experience in many, many ways. Thank you, George.”
✏️ “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!”
✏️ “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.”
✏️ “I got a perfect PSAT math score, thank you!”
✏️ “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!!”
✏️ “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!”
✏️ “We give high praise and appreciation to Dr. George for the effort and care he has put into our son’s math and science tutoring! Our 8th grade son just received his SSAT score report and is in the 99% of the Estimated National Percentile! Also, just as wonderful, is the noticeable increase in our son’s self-esteem and confidence! Dr. George has shown that his consistent and kind approach to teaching can lead to a strong sense of self! Thank you so much Dr. George!”
✏️ “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.”
✏️ “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.”
✏️ “George was everything we’d hoped for in an SAT tutor – and more. Just by the enthusiasm our son had for completing the between-session assignments (‘George work’ often came before homework!), we knew we’d made the right choice. Not only did he feel totally confident taking the SAT, his time with George helped him sharpen his ability to complete regular school assignments, as well; he is now tackling honors calculus with ease. Our son fully recognizes how much he benefited from George’s coaching: when his math SAT score came back 130 points over his first attempt, he said: ‘Way to go, George!’ ”
✏️ “Within the last two years, George not only fulfilled his duties as a tutor by helping me excel in Calculus and on the SAT’s but went beyond by helping me with the college application process and advising me based on my academic goals. Through out George mentored me and helped me to grow and develop the strong work ethic and skills that I have today and use every day in college.”
✏️ “George is a 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.”
✏️ “Whether in a group or individually George is by far the best tutor I have had. His knowledge is extensive and he teaches in a way that complex subjects are easy to understand. I’ve used other tutors and centers and none compare to George. He is such a great teacher that I kept bugging him to teach at my high school.”
✏️ “George has been an inspiration to our son! He now has the confidence that he can actually understand and be successful in math.”
✏️ “When George takes on a student, for him it is not just a job, for him it is a commitment which he honors spectacularly. A commitment to help you do well in school and also a commitment to actually learn the subject matter.”
✏️ “I used to hate math and everything to do with it. But now that I’ve been working with George and I am ahead in my work, I absolutely love math now. I can’t even tell you the satisfaction I get when I know all the math in class the first time the teacher tells us. Also, my grades couldn’t be better right now, and it is all due to George”
✏️ “George is not an ordinary math teacher. Not only did my son receive phenomenal math tutoring, but George also boosted his confidence. I’d overhear George encouraging my son, ‘Let’s look at the problem carefully, it’s easy…’ By upping my son’s self esteem, George was able to improve his score. George also built up my son’s stamina by having him take full length practice tests so he’d be prepared for the actual SAT.”
✏️ “George is a good guy. A+ tutor. Great results, my son scored a 730!”
✏️ “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 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.”
✏️ “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 has a very nice personality and is very smart. He has a nice way of conveying information to hold my son’s attention. George has been very helpful to my son, bringing his grades to a passing A and building his confidence in math.”
✏️ “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.”
✏️ “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.”
✏️ “We simply could not ask for a better qualified, kind and sincere educator for our son.”
✏️ “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 set an amazing foundation for my AP Physics course, when he taught me some basic calculus, which allowed me to understand how all the formulas interconnected, rather than simply memorizing them.” (AP score 5)
✏️ “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.”
✏️ “Even though my strength has always been in writing and English, I am now an A student in math and science as well because of George.”
✏️ “George brought my daughter’s math grades up from C- to A’s. He works well with my daughter and is very positive.”
✏️ “You have set the ‘gold standard’ that I don’t think anyone else can approach.”
✏️ “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)
✏️ “My son has been tutored by George for the last three years. During that time he has gone from a struggling student to one who feels a confident mastery of the subject. George has built up his understanding by patiently explaining the basic foundation of math as well as adding enrichment when my son was ready. He now loves math and we owe it all to George!”
✏️ “This is exactly what we have discovered in George – To Teach or Instruct Thoroughly. George not only has read our son’s Advanced Algebra book, he has wrapped himself around it. He teaches with enthusiasm and a deep concern for our son. He genuinely cares that our son not only understands the many different concepts but also makes sure that our son is able to effectively apply them. Our son has 125 new problems every week and George makes sure our son fully understands each and every one. Our son’s grade has improved from a B- to an A- and we expect this trend to continue along with his growing mathematical confidence. Our son smiles broadly at the end of every session. George is the MVP of the academic playing field! Thank you George.”
✏️ “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.”
✏️ “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.”
✏️ “Beginning with the very first session, my school work became much easier. George helps me understand math in a way I never did before.”
✏️ “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 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.”
✏️ “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)
✏️ "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.”
✏️ “You are the best!”
✏️ “I wish all students could have the opportunity to have such an excellent teacher.”
✏️ “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 did an excellent job working with our daughter over the past year. He built her confidence and knowledge base so she could execute complex math problems under time pressure. We believe that one of George’s key strengths is his ability to work with strong students in advanced classes to achieve top performance. In addition, our daughter had fun working with George. We will use him in the future.”
✏️ “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!”
✏️ “My son is a typical middle school boy – more interested in sports than school. George has been able to motivate him to want to learn and excel in math. His teaching approach has been tailored to my son’s learning style with good results. His enjoyment, understanding, and confidence in math has increased significantly. To realize that my son’s math foundation is solidifying for the high school years is a comfort.”
✏️ “Following a couple of years with disappointing math teachers, my son was struggling in his Algebra 2 course – and then the pandemic hit, and distance learning compounded his problems. At this point we reached out to George. George took the time to work back through the older material to build up a strong foundation for future success. The first few months were triage; even so, we noticed improvements in performance almost immediately. In addition to laying a strong mathematical foundation, George has done a great job teaching my son solid study habits and test-taking strategies. My son is comfortable with the material and confident that he will perform well on his tests. I am certain that my son is now on a trajectory that will guarantee success in math through the end of high school and beyond.”
