Mathnasium has been a game-changer for our family! Since enrolling my daughter, we’ve seen a dramatic improvement not only in her math scores but also in her overall confidence. For the first time, she’s actually enjoying math! The instructors are patient, encouraging, and truly know how to make learning fun and approachable. I’m so grateful for the support and structure Mathnasium has provided—it’s made a world of difference in how my daughter views herself as a learner. Highly recommend!

My kids started at this location over 2 years ago and improved so much in math. They make sure that my kids master all the math skills at their levels and also help them with homework when it is needed.

5 Stars – Mathnasium Has Been a Game-Changer for Kennedy!

We can’t say enough good things about Mathnasium! Our daughter Kennedy has absolutely thrived since starting the program. Math used to be a source of stress and frustration, but now she approaches it with confidence and even excitement. The instructors are so patient, encouraging, and truly know how to meet each child where they are.

We’ve seen huge improvements not only in her skills but also in her overall attitude toward learning. Her grades have gone up, and most importantly, she feels proud of herself. Mathnasium has given her the tools to succeed and the belief that she can do it. We’re so grateful for the support and highly recommend it to any parent looking to boost their child’s confidence and ability in math!

Roel and his team were quick and easy to accommodate our 11th Grade student enrolled in honors pre-calculus on short notice. Within a month he caught up missing assignments and lifted from a low 70% to a high 80% grade. He will continue now through the end of 12th Grade in order to lift the grade back to an A.

Cannot offer any higher recommendation than in person tutoring over video chats.

Mathnasium offers tremendous flexibility. They have a patient team of math experts. They are incredibly responsive even to after hours and late requests for support. Mathnasium is the only reason my son survived 10th grade math!

Thank you! Please tell us more about your great experience with us.

Our son began Mathnasium when he had high anxiety with math, mostly due to the constant "math facts" memorization push he has experienced at school for the past 3 years. Mathnasium has been a tremendous help for our ten year old! The techniques taught have helped our son improve with fluency, lessened his anxiety, and greatly increased his confidence! All in only the past 6 months! The incentive programs (prizes, etc.) help with a ten year old, who is over the moon excited when he EARNS prizes. We could not be happier with Mathnasium and would absolutely recommend it to other parents.
