Thank you so much for sharing this! We’ve loved watching both of your children grow in their math skills and confidence. What makes their progress especially meaningful is the commitment behind it. Building strong math foundations takes time, and your family has kept showing up and doing the work. Seeing one child move from behind to right where she needs to be — and the other move ahead of his class — is absolutely worth celebrating! We’re so proud of them, and grateful that you’ve trusted us to be part of their journey. ❤️

My daughter has improved with her math, which is a huge accomplishment.

The people working with my son are always happy to assist him and they are very approachable if he ever goes to them. It definite has honed his core math skills.

We are so happy with Dave and everyone at South County Mathnasium, they are so there for my Son for everything he needs. They answer all our questions whenever we have any. They send updates every time he had a session and explains exactly what he is working on and what he needs to pay more attention to. They genuinely seem to care about him and his math journey. They have helped him so much! Thank you everyone

My grandson seems to be making progress for the last two months. He doesn’t complain about going. I like that the work is done on paper instead of on an electronic device.

I cannot say enough. My daughter is starting to “like math” again! The curriculum starts with the most important part, the student. They began working with her where she is at, not where she needs to be. She has progressed and I couldn’t be happier. Thank you!

The help my child has received from Mathnasium has increased his confidence in school and with math skills used for every day living. This has been a boon for our whole family, and one of the best ways to invest in his future!

My son has struggled with math skills for the majority of elementary school. I research tutoring options and found Mathnasium. This was one of the best decisions I’ve made. Now, my son loves math and looks forward to each session. The program keeps him motivated and engaged. I can see he is more confident in himself. The instructors are friendly and understanding and take the time to make sure each child learns and understands the material that is tailored to each child’s specific needs. I couldn’t be more happier that I found Mathnasium to help my child.

We are enjoying the experience and staff. The kids like it.

Our student has more confidence in her ability and less anxiety about math.

This is exactly what we mean when we say “Changing Lives Through Math.” At Mathnasium, it’s never just about numbers on a page. When students build confidence in math, they begin to trust themselves — and that confidence carries far beyond the classroom. Confidence in Math. Confidence for Life. We’re honored to be part of that journey. 💙📚✨

I appreciate all the staff!!! They all love math and help my son improve and gain confidence.

While every one of our instructors has their own math journey, the number one criterion for being a Mathnasium instructor isn’t perfection — it’s a genuine love of helping kids. Yes, there are numbers and words on pages. But the real goal is something much bigger: ✨ independence in math ✨ confidence to ask for help ✨ self-advocacy that carries into life That’s how confidence in math becomes confidence for life. 💙📚

My daughter has not only brought up her grades in math but actually likes it! She loves going to Mathnasium and the instruction is very light and judgement free.

My experience happened when I was able to register my granddaughters this past summer for three weeks. Thank you, Dave.

I get no pushback, no complaining or protesting when I tell her she has a math session scheduled for the day. She told me, “Mom, they just explain it in a way that I can understand.”

Thank you so much for sharing this! That simple sentence from your daughter—“They just explain it in a way that I can understand”—means the world to us. It’s exactly why we do what we do. We’re so glad she feels supported and confident during her sessions, and we love knowing that math days are met with ease, not pushback. Thank you for being part of our Mathnasium family!

The owners are friendly and know their stuff! Both of them have backgrounds in math and know how to teach and talk to kids. My so was so shy at first, but now he asks to go to mathnasium! We tell everyone about this place
