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.

Proud to provide outstanding private tutoring for high school and middle school students. Customized instruction for Schoolwork, SAT & ACT, and SAT Subject Test preparation. I empower my students with knowledge and comprehension, teaching them to think clearly, become creative problem solvers, and excel with competitive advantage. This results in top grades at school, highest standardized test scores, and future success. When our children go to college, if they have the best foundation and know how to think on their feet, they will be confident and successful, and we parents won’t worry. Please visit the about page to learn more about me. I have educated high school and middle school students online for years, and my expertise includes the rare art of properly crafting minds at these important stages. My goal is not just to have set the bar for the best private instruction available, but to continuously raise it.

Hundreds of testimonials with prominent named verifications for my own work with students. Please take a moment to read them. I prefer no hype, and what matters is a long-term track record of successful students.

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!!
