Proud to provide the best private tutoring available to Winnetka for high school and middle school students. The most important validation is what parents and students have to say, so please read the growing list of hundreds of testimonials with prominent named confirmations. Whether focusing on Schoolwork, SAT, or ACT preparation, I teach and mentor my students to think and become creative problem solvers. A true master apprentice relationship. This is the foundation which results in good grades at school, high standardized test scores, and future success. When our children go to college, if they know how to think on their feet, they will be confident and successful, and we (parents) won’t worry. Perdocere is a true one-person premium tutoring company providing unmatched educational excellence for each and every one of my students, from Winnetka, across the country, and even when they study abroad.


I think George is not merely a tutor – he is a real educator. He knows that what helps students perform well on tests is the same as what makes them good students. A solid academic foundation pays dividends throughout schooling and careers, and George never loses sight of that in his work.

”We are ecstatic about the progress George has made with our daughter’s math scores. He has instilled possibility when she knew only defeat. The experience of success in math has given her tremendous confidence. Higher math had been out of her reach, but now it is easily grasped. George’s knowledge is boundless, not only in math, but also in knowing how and when to motivate psychologically and emotionally. He is always prepared and upbeat, and he keeps each session moving enthusiastically. Our hope was that George would just give our daughter the jump start she needed, but in fact, he has become a part of our lives for years.”
