​I can say with total confidence that Ms. Raven is the most responsible teacher I've encountered across all the after-school programs we've tried. Her dedication is unmatched. ​Why This Program Stands Out: ​Personalized Progress Tracking: Ms. Raven tracks every student's progress weekly and personally calls parents to provide updates and listen to any feedback or suggestions. ​Shift in Attitude: My child went from hating math to actually being willing to attend. The "Reward System" they have in place is very effective at keeping kids motivated. ​Self-Paced Learning: Students can work at their own pace, which gives them a great sense of freedom and reduces pressure. ​Curriculum Balance: The material is a mix of what they are currently learning in school and new concepts they haven't seen yet. While it doesn't strictly follow the school's timeline, it keeps them challenged. ​No Homework: Perhaps the best part is that there is no extra homework to bring home. For a child who is already resistant to math, this is a huge plus. ​Ultimate Flexibility: They are open Monday through Saturday, and you can drop in at any time. There are no fixed class slots, which is incredibly convenient for a busy schedule. ​Bottom Line: If you are looking for a supportive environment where your child can overcome their fear of math without the burden of extra homework, I highly recommend this place! read more

All three of my kids get tutoring here. One of my kids first started coming here last summer of 2025. My son was struggling with math due to his difficulty in focusing, understanding the concepts and overall the language of math. I have seen dramatic changes with his math skills, confidence and it also helps that he looks forward to coming here. During the summer of last year I was so surprised in his speed and understanding of math. He also became really great in doing mental math. I am unsure if Mathnasium had anything to do with it but regardless I am satisfied customer and a happy mother. My son also has had some bad days due to his personal behavior but Raven and the tutors are incredible. They are professional and do no lose their cool or their demeanor when my son tries to tests his limits. My daughter who is 7 years old could come here every day if she could. Many times shes the one asking if she could go even when her two brothers are not with her. She loves the incentives. They definitely keep her motivated. Raven is friendly, personable, professional and is great at updating us with the kids progress. Many times when she is not talking to parents I love to chat with her and pick her brain about anything related to math, learning styles, kids behaviors, etc. My only suggestion and hopes for the future plans with Mathnasium is if they could be open on Fridays and expand their hours. read more

Of all the tools and services we've used to help our our 5th grader with math such as tutoring, books, other learning centers, Mathnasium seems to have had the most impact on him. I'm sure the in-house prizes help motivate him too, and now two of his siblings have joined him. It's like the only educational activity of the week that they all look forward too lol. read more

This program has been super helpful for my 9yr old. Instead of focusing and relying on memorization and repetition, they actually teach and explain concepts so the kids can understand and be able to solve problems on their own. My son has been coming here for a few months now, and I have seen an improvement in his grades and his ability to grasp new math concepts he learns in school. I love that he can bring his homework here and get help and more explanations on the things he doesn't understand. I feel like this has been more helpful than his teacher at school. Definitely recommend! read more

My 7-year-old LOVES Mathnasium and begs to come! She loves math and wanted to learn more advanced concepts than what was being taught in school, and Mathnasium was a perfect fit to challenge her and really foster her love for math. Chris and his team are amazing and the way they teach and help the kids really shows that they love what they do and care about the students. Even if my kid didn't like math and just needed the extra help for schoolwork, Mathnasium's fun rewards program is a really great motivation to keep kids coming and doing their best. So glad we found Mathnasium and we look forward to coming here for a long time to come! read more

Mathnasium of Diamond Bar has one of the most personalized learning programs for elementary through high school children. They are conveniently located 5-10 minutes away from Diamond Bar High School. You will find a team of well-trained teachers here who use various methods such as verbal, visual, and kinesthetic to help your child develop a richer mathematical foundation. They have excellent programs designed for middle/high school students who are enrolled in Geometry, Algebra, or Calculus. Their interactive ways of teaching make mathematical concepts fun and easy to grasp, unlike other tutoring services where you'd expect worksheet after worksheet. Mathnasium's tutors are kind, friendly, and fun to work with. You will immediately find yourself a new friend as soon as you step in.

Teachers are sensitive to adapt to each student's learning style to provide the most comprehensive and interactive learning experience that I know by far. read more

As my son ends his almost 2 years at Mathnasium he is more confident in his math skIlls and he loved going here. At first he was like really mom but to be truthful he is sad it is coming to an end. Kathy and Nick have been so flexible with us and I know they really care about my child and his learning plan. The tutors as well are very considerate and I know he has a special bond with everyone there. This is like a second family for my son and I can't wait to see what he can do after this journey has ended. Thank you Kathy and Nick we will pop in to say hi from time to time. read more
