Customer Testimonials
Joseph and his team are doing a fantastic job. My daughter is doing much better now with math.It’s a good investment and highly recommend it.
My son very like Mathnasium!
The instructors are very patient and able to provide clear instructions to students in an encouraging manner.
My daughter’s experience has been great thus far. The staff and environment is safe, clean and friendly and the tutors are wonderful at their job. I would recommend.
Our 10 year old son attended Mathnasium for 6 weeks during the summer he really enjoyed the math practice which was tailored to his specific needs. Staff is professional, dedicated and patient.
My son wasn’t very good with math before coming to Mathnasium. My son has learned a lot.
Mr. Joseph Lee received and returned my calls promptly. He is also understanding and accommodating of our family's needs when I told him I am only interested in bringing my child for the summer. My child was assessed first and so they have a baseline of what he needs to work on. This is the first time I needed help tutoring and the other center is charging an arm and a leg. Though my child seemingly could care less in the subject matter and is so mum to share more than a word or two about anything you asked, I would say overall it is a positive experience since the child is willing to go there each and every time, on time. I am sure also that it is not about the cool places to eat next to Mathnasium, that is a plus!
Joseph and Paul is amazing! They really care for your children's progress in math. 
I really trust them will help my daughter math's grade. 
Thank you for working hard to help improving my daughter's grade in math. 
Great first impression. Joseph is very professional. My daughter enjoys Kelly teaching her
I would definitely recommend thus program!!!!
My son’s been in Mathnasium for maybe 5 years now and he always admire the tutors the way they explain to him that he can understand it and not stressing out in class work and quizzes in school.
我女兒在去年7年級數學一團混亂狀態很受挫折,在Joseph Lee 老师坚持不懈的耐心指导下,她对數學在慢慢地理解和進步。
My son has only been going for 3 weeks & he's starting to be more comfortable with math. He struggles so much & the staff here has patience. He likes that they make it understandable not like school.
Joseph and his team are amazing. They truly care about the students they tutor. Ut is more than just a job to them.
Great staff!!! Help my kid remain at the top of her class.
Joseph was great, very understanding and accommodating
My son has a better understanding of concepts than before starting the program. He also feels more comfortable asking questions in a small setting than thorough distance learning with his school.
Joseph Lee and his team were great with assisting my daughter with her Integrated Math 3 class. That is her toughest subject and she received a B+ in the course, a huge accomplishment for her.
Mathnasium helped my daughter fill in the gaps so she could catch up. They were very flexible if we needed to reschedule. When Covid hit, they were able to get up and running pretty quickly via Zoom. They did not give me any trouble when I wanted to take a break, which I appreciated.
My sons grade has improved tremendously once he started with a tutor! He went from barely passing to an A! Not only does he get help with daily homework and test review, he also works on the basics. I’m also grateful that he can attend one on one right now because he’s not getting that during remote learning at school. I will continue to take my son as long as he needs it. I highly recommend!
My son loves Mathnasium. He has been for the past two summers and has asked to be enrolled during school. I never thought he would be asking to be in math tutoring and never thought he would be so excited to attend. He has been getting help with his homeowork when he attends and has also been getting the day's lessons reinforced. He was struggling with math and now he is doing well. I am so appreciative of all the help he has gotten at Mathnasium. Thank you.
My son was struggling with AP Cal AB and Joseph, the owner of the center, has been tutoring him and doing a great job. My son said after the first lesson, he understood the material better and that Joseph did a great job of explaining the material to him.
We had a wonderful experience in Chino Hills. I would have preferred more Hands-On interaction with games, coaching and teaching. I have referred magnesium to a few friends. One has signed up with a closer location.
I would recommend this place to every parent I know who’s child needed to grow in math skills!
My son loves how knowledgeable and fun the instructors make it for him. They are caring and teach him awesome ways to help him understand the math. He always comes out of tutoring with a smile & with the confidence to tackle his math assignments.
My kids love the teachers and both Mr. Lee at this location. They are patient and kind in teaching and explaining the math problems, in order for my kids to understand. Thank you!
The Mathnasium team is very attentive to my daughter's needs. Math is, by far, her most challenging subject and Mathnasium has made it possible for her to get through these classes.
Owners are very nice
Great program I highly recommend!!
