“Tim is a genius who, through humor, kindness, and unbelievable teaching skills caused both of our middle school-aged children to LOVE math. After his classes, both felt competent and confident in their skills to approach any problem.”

“I've struggled deeply with math my entire life. Mr. Ricchuiti's lessons made the subject understandable and engaging, and I improved my math sub-score drastically. His lessons led to a 110-point improvement in my SAT score.”

“He has an astute ability to distill complex concepts into bite-sized pieces. Quick to encourage yet measured in his tone. To put it succinctly: Ricchuiti is a really, really good teacher. The one you recall years later.”
