Customer Testimonials
Grateful for the leadership, culture and approach to learning at Mathnasium, and a more confident child!
Excellent program! My children are excited to come and love the praise system! Thank you to all the staff !
Mathnasium in Portsmouth has been a great way for my children to keep their math skills sharp over the summer. The staff is incredibly friendly and professional and do a great job of keeping the children engaged. They find creative ways to make math enjoyable, and my children want to return as a result.
One of my unique things about Mathnasium is the sense of community. My children always look forward to seeing their friends when they go, which makes it feel like more than just a place to go to practice math. The positive environment and encouraging staff have made math something they actually look forward to.
We're very happy with our experience and would recommend Mathnasium to other families looking for extra math support in a fun, welcoming environment.
Initial conversation with Ryan was very professional and helpful. Elijah was excellent with Keelan and she made progress with her other virtual instructor. This was a positive experience. Highly recommended
Such a positive environment. They're making math fun for our child.
First, I’d like to say thank you so much to you, Sean, for always being so kind, flexible, and supportive. You and your team have completely changed the way my daughter sees math. Before coming to Mathnasium, she hated math and didn’t believe she could do it. Now she enjoys it, believes in herself, and has so much more confidence. It has truly been an amazing transformation.
Debbie creates such a positive, supportive environment, and the instructors are fantastic, knowledgeable, patient, and wonderful at explaining complex concepts in a way that truly clicks. 5 Stars!
Harper said, “Give them a 9. They really are a 10, but they need to stay humble.” In all seriousness, this has been a wonderful organization and has helped Harper not only grow in math, but also come to love it. THANK YOU a million. We sing your praises at every opportunity.
Two of my sons attend mathnasium. One loves it! He is super motivated to go and always has a great time. His teacher says he’s doing really well in math. My other son is less enthusiastic about it, but that is probably due more to his age and disposition rather than Mathnasium’s itself. It would be nice to see the kids do more than just worksheets all the time. Thanks!
David and his team has been great! They have worked with my son and he is learning so much.
Kid friendly environment - seeing results already and very impressed by my sons progress so early.
The plan is individualized for each student. Instructors are vetted, friendly, and know how to teach. The owner, Maggie, is a strong teacher/instructor and leads her team intentionally.
The staff is so kind and accommodating. They know every single kid that comes in by name. Very happy we found them to help my child catch up!
My son is loving Mathnasium. I thought it would be a fight to get him there but he loves going.
It has helped him tremendously boost his math skills and confidence.
I am very happy and grateful to enroll my kid into Mathnasium. It improved deep understanding of math skills and also helped to get high score in math which gives a profound impact on transcript.
I have been sending my children to Mathnasium of Rivervale-Westwood since 2020, so they must be doing something right. I appreciate the environment, the focus on learning, and the motivation to enjoy math that comes from the teachers and staff. I am very impressed with our new director, Liz, who has followed up with me and the children to make sure that our Mathnasium goals match our school and standardized test goals. Highly recommend this location for those seeking math support and enrichment!
We transitioned from a different math program last year and couldn’t be happier. Matthew and Drew are one of a kind. The tutoring and practice is catered to the child’s needs based on their level. Easy to book, modify and cancel. Overall would highly recommend.
Amelia has improved a lot due to you guys. Keep up the good work.
Mathnaisium is a supportive but relaxed environment to work on math, which really helps my son focus. Happy client for three years!
We’ve had a wonderful experience with Mathnasium! My son, Mathew, has been attending for over two years, and he genuinely loves going. The instructors are patient, knowledgeable, and do a fantastic job making math engaging and enjoyable. We’ve seen a noticeable improvement in both his confidence and his problem-solving skills.
What stands out most is the positive and encouraging environment—they make learning fun while challenging students to reach their full potential. It’s rare to find a place where a child is excited to attend, but Mathew always looks forward to his sessions.
We’re so grateful for everything the team has done for him and highly recommend Mathnasium to any family looking to help their child build strong math skills and confidence!
My daughter looks forward to going to her sessions, even thought at school she has often avoided math. I love seeing her confidence grow. I'm really hoping this carries over to the school year.
My kids are LOVING the program!
My daughter loves going to Mathnasium. She feels proud and excited when she masters a new skill. Her math skills are strong, and going here has helped her to love math, even the challenges.
Since enrolling, my daughter’s math average has improved dramatically. More importantly, she’s much more confident in her abilities. We couldn’t be happier with the progress she’s made. Thank you to the entire Mathnasium team!
Great atmosphere, the staff are super friendly and accommodating, and most importantly, my kids love being here working on their math skills!
Mathnasium was very accommodating with our requests and was always trying to find a way to help our son. Also, whenever we were there, they were cheerful and supportive. I think Mathnasium is doing a great job.
Great staff and fun experience overall for my child. It takes the edge off of a very stressful and challenging subject and allows more of an open mind ready to learn!
The instructors are great!
We truly appreciate Mathnasium and feel very grateful for their amazing team. Dimitry, the owner, is such a kind and caring teacher, and his support means a lot to us.

The instructors are helpful, friendly and able to adapt to students needs and questions. My student has been attending for about a year and when she is struggling with the explanations from the classroom the Mathnasium instructors have always been able to provide alternative explanations or break the problem down a teach the processes needed to consistently solve the type of math problems that have her stuck.
