Customer Testimonials
like you guys . thanks for teaching the kid
We are so appreciative that Mathnasium in Diamond Bar was able to help our son! During the pandemic he got behind in Math and within a few months the tutoring sessions really helped him catch up to feel confident to start middle school. We had a wonderful experience and thank Chris for working with us.

Before going to Mathnasium, my third grader always said she hates math. Now she is very happy and comfortable to go to the class and it’s great to see her making progress over time!
Simply amazing!!!
I love the curriculum, I feel it is really helping my child understand the "how" in math rather than just memorization.
The staff and teacher are wonderful, Chris is super helpful and patient in answering our questions and helping us troubleshoot issues with schedule.
Great
Our son is excited about learning Math! Our son struggled and lacked confidence with his math skills. Today his enthusiasm to learn math is a great accomplishment. He speaks about math after his lessons and wants to show us everything he has learned. He looks forward to his math lesson at Mathnasium and the wonderful staff.
We know that this will be carry through out his life. Thank you Mathnasium and staff, for the gift of Math!
Our son has been enrolled at the Diamond Bar Mathnasium Program for 5 years now. He started as a 5th grader and today he is a freshman. Currently, he has earned an A+ in his Integrated Math II Honors course which has assisted him to excel in his Engineering Design Pathway program. In the 5 years of participation he has been taken care of by the the best center directors, Nick van Vliet, Kathy Chiang and today Chris Hoover that hire great instructors that offer the needed support.
We highly recommend this program. We are satisfied with the results and agree that it is a beneficial investment for our son’s educational needs.
Thank you Mathnasium of Diamond Bar Team
rapid progress
The kids never argue to attend every single class, they love it! Great teachers and environment!
Great instructors and a great place to learn math!
A very conducive environment to learn (teachers, students and administrators all work colaborately and in a respectful manner to each other, so making learning math fun and enjoyable). Unlike taking other extra lesson, the kids always look forward to joining the class without complaining.
We appreciate all the great instruction our 14 year old teen is receiving from the Diamond Bar Mathnasium team. Our son continues to progress with an "A" grade his 9th grade year. The online math instruction is very effective in keeping him motivated to do well in Math. He has been a Mathnasium student for five years and I attest that it has been an essential educational investment and highly recommend this program to others. Thank you Chris, Nick and Instruction Team for all you do!
I love the small class size and the customization of the kids progress ....
Mathnesium catapult my kids to another math level! I highly recommend Mathnesium!
Kathy and Chris did wonderful jobs managing the center and getting kids to love learning math. This means so much for kids, and building a strong foundation. Thank you so much!
My daughter has been with Mathnasium for years now and I couldn’t be happier. Kathy, the director, keeps me updated on progress while the tutors work hard with my daughter on homework and mastering new skills. During the summer, they have always worked to prepare her for the challenges of the upcoming school year. Excellent group of people!
Our son has been doing well with the @ home lesson plan. He maintained an A grade with outstanding citizenship in his Math class his 8th grade final year of middle school. He will soon enter High School. We are excited as he is preparing with Mathnasium to enter International Math II through the @home lessons summer camp. We appreciate this option during this pandemic period. The Director Kathy Chiang and the Math instructors have been amazing with our 14 year old son. Our son has been participating in Mathnasium since 5th grade which makes it 4 years and has impacted his success in Math. We will continue to invest in Mathnasium to make sure our teen continues to excel in Math.
Thank You Diamondbar Mathnasium Team!!! We appreciate you!

Mathnasium has been great. Our son has improved so much on math. Kathy is great she checks up on my son when we are busy. It has been a great experience.
The kids are more confident when doing their math homework.
Great teachers and great methodology. Friendly atmosphere. Kathy cares about the students and is very helpful.
Kathy and her team are doing a great job with the zoom @home program. My son was not left behind during the current pandemic shutdown.
Most important, due to the instruction received my son earned an “A” this quarter in Math. He is in 8th grade. We are extremely thankful.
Wonderful staff
My son’s attitude towards Math has since changed because of Mathnasium. He would dread going to Mafh class before, now he’s more confident and likes the subject. He loves all the teachers in Mathnasium Diamond Bar.
Mathnasium in Diamond Bar has an amazing staff. They’re experts in math and care about their students. My daughter has been enrolled for a month. We are excited to see her feel more confident in math and improve.

What we like is they help the child to understand why we do it this way. Other places just show you how to do and not explain. The best part is they will even help with homework now this is teaching the child real-time math learning.
