Customer Testimonials
I decided to enroll my daughter at Mathnasium because she was really behind in math. She has been with Mathnasium a little over a year and I’m really happy with my daughters progress.
Lenny and all her staff are awesome! My 3 kids love going to their weekly classes everytime. They encourage their students to strive better in their Math lessons. with positive reinforcements (praises, fun prizes when they reach a certain goal etc…) which really work for the kids. They even have birthday gifts and cakes for their students’ birthdays. The teaching staff are all so knowledgeable and efficient. My kids find this place a very fun place to learn Math. —First name removed L.
My daughter went from been an F student to an A+ student. Thank you very much!
Lenny is the best!
My son has struggled less in math since I’ve brought him here and is doing much better in school and that’s why I also enrolled my other son as well to help him with his struggles in math.
Also the service is really good and I like how staff treat you and are pretty good at rescheduling if needed without hassle.
Lenny is great! Very kind, and very organized. She’s efficient and structured. The tutors are patient and give good clear instructions. My boys enjoy going!
Instruction is strategic to the curriculum of the grade level of student.
My son Moses really enjoys working with his tutor Daniel!

Such a great place to enhance Math skills!
This is a fabulous location for learning to take place. Ms. Lenny is truly amazing and she cares about all of the students. My daughter has been attending for 4 years now. Her confidence level in math is high and she is getting As in math. You will not be disappointed!
Great tutors, clean, and very helpful.
Ms. Christine Lenny had been very helpful all throughout my son’s involvement with Mathnasium. We feel very comfortable sending our son back to in-person learning because she keeps the center absolutely clean and strictly enforces regulations that will keep both students and her staff safe. My son learns a lot from his tutors. He does extremely well in school as well as with his GATE testing because of the extra support he gets from Mathnasium in Rancho Cucamonga. I highly recommend this place.
Ms. Leny and her staff/teachers are all great! My son is not a natural at math and he’s improved greatly through Mathnasium! It’s also helped him with better grades with math at school

My daughter has never liked tutoring until Mathnasium. She thinks the teachers are very nice and she feels comfortable learning there.
Great place to learn math. All my 3 boys love coming here not because they learn so much but they also have fun with earning rewards for finishing their work. The center really knows how to motivate their students to put in their effort. Highly recommend this center.
Mathnasium had helped my kids continue to excel in Math. The atmosphere in the center and the amazing teachers contribute to my kids enjoying learning math. The bonus is they feel confident in their math classes at school.
Thank you Mathanasium, my kids love math because of you all ❤️

My son has been attending here for a little over a month now and his confidence in his math skills has improved and he isn't struggling like he used to to do his homework. I'm so glad I found Mathnasium and that it's helped my son with his math. I would definitely recommend this place to anyone.

My daughters skills are improving, her attitude is more positive and she loves the reward options.
