Customer Testimonials
My son is now in 9th grade and progressing steadily as he prepares to take the Regents exam this year. Looking back, I’m incredibly grateful we found Mathnasium when we did. My son had fallen significantly behind in math during the pandemic, but within just two months of starting at Mathnasium, he began mastering his math facts and gaining real confidence. He started passing all his exams and improving week after week. He actually enjoys going, which makes a huge difference. The owner Rich is hands on, and is very vested in the kids success. He checks on their progress and reports what he is working on, keeps me informed as well as giving me suggestions to help him succeed. The entire Mathnasium team is fantastic. My only regret is I didn’t start him there sooner
Our experience with Mathnasium has been fantastic. The instructors are patient, knowledgeable, and really know how to connect with students. Marcus has gained so much confidence in math since joining, he actually looks forward to going! We’ve seen noticeable improvement in his skills, and he’s even starting to enjoy the subject more. The personalized approach really works, and we’re grateful for the support Mathnasium provides.
My daughter loves coming here. She learned a lot. The staff is wonderful & attentive to individual student needs. Highly recommend.
I can't thank you enough for the incredible support you've given my son. When he started tutoring just a month ago, he was really struggling. Even basic concepts like fractions were a challenge. But now, the improvement I’ve seen in such a short time is amazing. His confidence has grown, and he’s actually excited about learning again!
Your program has made a real difference, and I’m beyond grateful. I highly recommend your tutoring services to any parent looking to help their child succeed.
My son had missed a few lessons in pre algebra and started to fall behind. Within a few short weeks his grades were back where the should be and he doesn’t give me a hard time about having to go the Mathnasium.
