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

Colleen, the director at Barrington Mathnasium, is one of the easiest people to work with because she is responsive, understanding, flexible, and just an overall nice human. My two boys (ages 12 and 15) enjoy going because her staff makes learning fun! The staff makes an effort to get to know the kids and are knowledgable in many math focuses. We started almost a year ago and my boys’ confidence in math has soared using her program. They used to struggle to keep a C and now they’re on the brag board for earning As on tests!! Per Ms. Colleen’s advice, they worked hard throughout the summer reviewing material they’d missed or struggled with and have gone into this new school year with their heads high and confidence in their abilities! I cannot recommend this program enough!

Response from Mathnasium of Barrington:

Thank you so much, Tiffani, for your incredibly kind and thoughtful review! It has been such a pleasure working with your boys over the past year, and we couldn’t be more proud of the progress they’ve made. Seeing their confidence grow from struggling to maintain a C to celebrating As on tests and earning spots on the brag board is exactly why we love what we do!

We’re especially glad to hear that they enjoy coming to Mathnasium and that our team has been able to make learning math fun while getting to know them as individuals. Their success is a reflection of the hard work they’ve put in, especially over the summer, and we’re thrilled to see that effort paying off as they started the school year with greater confidence!

Tiffani, thank you for trusting us with your boys and for being such a wonderful part of the Mathnasium of Barrington community. Your recommendation means so much to our entire team. We’re excited to keep cheering them on and watching them reach even more of their goals!

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

Mathnasium is a wonderful program run by truly caring and dedicated people. The staff has helped my daughter strengthen her math skills while gaining greater confidence in her abilities.

I believe the key to learning and retaining math begins with a disciplined approach and a strong understanding of mathematical principles. Damien has guided us through this process and developed a thoughtful, structured program for my daughter to follow. His approach is helping her build greater skill and mastery in mathematics while creating a strong foundation that will prepare her for college and future success.

We are very grateful to Damien and the entire Mathnasium team for their encouragement, professionalism, and commitment to helping my daughter excel.

We’ve been really happy with the service! I love that you’re able to incorporate what he’s working on in school into the sessions—it makes such a difference and helps everything click a little more.
We’re also starting to see his confidence grow, little by little… baby steps! And honestly, it’s been so nice to watch. He’s becoming more comfortable and confident as he goes, and that’s been one of my favorite things to see.
Thank you for being so patient, encouraging, and for meeting him where he’s at. We really appreciate all the support!

Response from Mathnasium of South Barrington:

Nancy, we have seen such a change in your son since he started with us! He's worked through quite a few learning plans and our Numerical Fluency program was a game-changer for him. He brings a smile to my face when I see him coming in the door! Thanks for your comments! ~Juli

The initial score reflected my perspective as a parent who works to support her little girl in building the confidence and learning experiences she needs to move to a larger classroom setting. I appreciate the support she receives from the entire team, including Jack and Kyle, to make this happen. Understanding the strategies behind your work helped me better grasp the process, and I trust your work. I hope to see Aylin progress and be ready to enter the public school system next fall. Thank you for the deligence and support.

Mathnasium has been integral to my son’s review and mastery of core algebraic concepts; this knowledge and confidence equated to an improved letter grade second semester.

I highly recommend Mathnasium for all ages and abilities. The staff is caring and accommodating, and my son greatly enjoys his sessions at Mathnasium.

Wish we’d done it sooner! We couldn’t be happier with the staff at Mathnasium Lake Forest. Even though I don’t spend a lot of time inside, I feel like I know the team through my kids. The director and assistant director do such a fantastic job creating a welcoming, encouraging environment.
I’ve probably recommended Mathnasium more than any other activity or sport my kids have been involved in over the past several years. It’s been one of the best investments we’ve made in their confidence and growth.

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

Since attending Mathnasium of Naperville, my son’s (8th grader) grade jumped from a C to an A. The grades are great, but the confidence and joy of learning are the true gifts he gained. He’s enthusiastic to share what he’s learned and looks forward to tests and quizzes! Can you imagine? He looks forward to the challenge because he knows he truly understands the concepts. We couldn’t be happier with our decision to join this amazing community. He looks forward to going every time. He loves the tutors, the other students, and the director. They found a way to make learning math stress-free and fun!
