An unparalleled online tutoring experience. Outstanding teaching (forgive the immodesty, but what’s true is true) together with real-time two-way writing and other interactive technologies. The photographs show Perdocere’s pen enabled online tutoring. Every lesson is one-on-one and customized to the needs of my students. We don’t fumble with a mouse to write equations, nor work at a reduced pace with generic tutoring software. Together, we write and share information effortlessly during lessons.

The most important validation is what parents and students have to say, so please see the growing list of hundreds of testimonials with prominent named confirmations. Reading through these testimonials will be more informative than anything I could write on this web site. I have tutored students online for years and have fine-tuned the online educational experience. In addition, by tutoring online, my huge collection of books and resources is readily available. For example, when one of my students chose to spend a year abroad in Viterbo, Italy, the system worked seamlessly. With the onset of COVID-19, I was already providing unrivaled online tutoring. In my own home, I send my children to their computers to receive my instruction, it works that well and is that engaging! No matter where you are, if you have a good internet connection and desire the best possible instruction, then I welcome your call.


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)


Practice problems in blue appear throughout my website and change periodically. Topics and difficulties vary. Have your children try them.

This is a simple but fun piece of math. Chose any integers p and q, where p > q, and the relationships below will generate Pythagorean triples.

\[\begin{array}{c} \color{blue} { \eqalign{ & {a^2} + {b^2} = {c^2} \cr & a = 2pq \cr & b = {p^2} – {q^2} \cr & c = {p^2} + {q^2} \cr} } \end{array}\]

Once your child has worked with George, you realize what an extraordinary teacher he truly is. George not only teaches in a professional and organized manner, he has instilled self-confidence in our son that goes beyond mathematics. Our son respects George not only for his ability to teach him, but also because he takes an interest in him personally. George not only gives careful consideration about what is being taught now, but what skills will be needed in the future. Our son took a higher level mathematics course this year than was recommended, and with George’s help he was very successful! He is a wonderful mentor, something we never expected! Thank you George!!!
