Janet Leventhal is the very best. Over several years, Janet tutored my sons in math as well as physics and chemistry. She was extraordinary in her ability to deconstruct course material so it would be easier for my sons to understand. She clearly and enthusiastically explained topics they had found confusing, and she worked with them to ensure they truly understood the concepts covered in the classroom and homework assignments. Janet’s talent as a tutor helped my sons succeed in chemistry, physics, and math. More important, her tutoring nurtured their confidence and fostered true joy in learning. Our entire family is very appreciative of Janet and the wonderful tutoring service she provides, and we give her our highest possible recommendation.

Janet is an exceptionally knowledgeable tutor . . . She is undoubtedly one of Sonoma/Marin County's best tutors. She can provide exceptional clarity and insight into a difficult concept that enables me not just to finish a homework problem but to comprehend the material truly. . . . Janet is an incredibly patient and empathetic tutor. She is my mentor and unwavering supporter who always cheers me on when I feel like I've hit a tough spot.

My daughter really loves Janet’s approach to math tutoring. She is thrilled to be doing so well in honors precalculus. She had struggled much of the school year, but now she is even enjoying the course! We are definitely going to seek Janet’s help for AP Calculus next school year. We had quite a time finding a suitable math tutor before we found Janet. We tried many individual tutors and tutoring services, but we kept finding the math tutors to be ineffective, unqualified, or both. We are grateful our friends told us about Janet.

Janet worked wonders for my son who started his school year struggling in chemistry. She was quick to recognize the instructor’s teaching style, and she translated difficult concepts into easy-to-understand terms. Janet’s expertise, along with her friendly and very patient manner, made it possible for my son’s grades to improve dramatically, way beyond our expectations. Janet truly dedicated herself to my son’s success by arranging time beyond what was scheduled when necessary, and she was always available to help, even late at night by telephone for last-minute study questions. If your child wants to learn and you’re readyto help him or her achieve the highest grades possible, Janet is the best!

Our son had terrible trouble with AP Physics and was feeling defeated. After two physics tutors over three months failed to help, Dr. Leventhal was our last hope. I did not want my son to end up with a C in the course! With Janet’s tutoring, he quickly went from C’s to A’s, and he achieved a five on the AP exam. Who would ever have thought! Other parents in my network say Janet has been marvelously helpful for physics, chemistry, and math at all levels. We strongly recommend Dr. Leventhal.

Janet is an outstanding, intelligent, and extremely helpful tutor. Her tutelage has increased my exam scores by two letter grades (on the last exam I received the highest grade in the class!). Janet’s skillful approach to teaching is evident through each weekly session because not only does she have patience and care for each student, but also it is obvious that she really enjoys what she does and that makes you want to do so well. For every new chapter we cover, Janet has a natural way of explaining the material and using great techniques to ensure that the material is making sense. Janet has given me a strong foundation for understanding a complicated subject and instilled in me many wonderful tools that will help me succeed in my future education.

Dr. Leventhal’s online tutoring was extremely effective. Because of her great experience and deep understanding of math and science, she was always ready to help me gain the skills I needed. She let me call her back later at night or email her with last-minute questions at no extra cost, and she was always willing to explain things until I understood. Dr. Leventhal’s tutoring was instrumental in raising not only my chemistry, physics, and math grades, but my confidence as well. She is a calm, patient, and understanding tutor, and I would recommend her to anyone who is struggling in a challenging subject.

We are grateful for Janet Leventhal’s help for our son in his very demanding AP Calculus course. Even though he was an honor student throughout high school, this particular class was very challenging. Within a few sessions with Janet, his quiz and test scores quickly improved. He was also better able to handle the nightly homework load, and his confidence in the subject improved. Within one month his grade in the class improved from very poor to very good, and he earned the highest score in the class on the final exam! This improvement preserved Jacob’s fine overall academic record so that he graduated with highest honors and was accepted at his college of choice. We enthusiastically recommend Dr. Leventhal.

I’m forever thankful that Janet was my tutor. Janet was very significant in my academic life for the last years two years of my high school career. Her tutoring in precalculus, AP Calculus, and AP Chemistry didn’t just raise my grades by a lot over the many months I got to see her. It also raised my morale and self-esteem; it convinced me to work harder even when she wasn’t beside me; it made those challenging classes fun and explainable and doable. I would help my friends in the classes, and it was like she was helping them. It was amazing. Having Janet as my tutor was one of the best things that could have ever happened to me in high school.

Six weeks before school ended, I received a notice from school that my daughter was failing AP Chemistry. Her only hope was to pass the AP exam, which would give her an automatic A in the class. We contacted Janet, who immediately responded to the challenge. In the little time she had, Janet managed to explain a year’s worth of chemistry to my daughter, who then scored a 5 on the AP exam, and saved her GPA! We are indebted to Janet: it was one of the best investments I’ve ever made. Needless to say, she is highly recommended.

Prior to obtaining the services of Dr. Leventhal, we contracted the services of private tutoring agencies for which we were paying moderate to high fees for ‘tutors’ who didn’t possess one tenth of the skills or background that Dr. Leventhal possesses. After a year with such tutoring agencies and with Ryan’s grades remaining the same, we decided to seek an alternative source of help. How fortunate we were that a person of such caliber came into our lives. Dr. Leventhal assessed the situation and immediately knew what Ryan needed; her patience and remarkable academic abilities were the perfect match. Ryan’s grades improved within a short time, which has allowed Ryan to go beyond what he had hoped. The student’s needs always come first with Dr. Leventhal.
