And we enjoy working with them! They're always smiling and ready to work, their positive attitude is very contagious when they come in!
Our experience at Mathnasium has been fantastic! When my son started at Mathnasium at the beginning of 6th grade, he tested at a 4th grade math level. By the end of 7th grade he finished the 8th grade curriculum with an A! We have a unique set of circumstances, so this probably isn't typical, but suffice it to say, my son doesn't struggle with math anymore, in fact, he's doing really well in his advanced classes at school & he actually enjoys going to Mathnasium! I would highly recommend this program to others with kids that are struggling, it really does help!
Rhine always likes to come due to thoughtful structure of the program, great teachers and innovative environment

Mathnasium has done wonders for our daughter in helping to reinforce math fundamentals to help her have a strong foundation in math basics.
Strong foundations lead to great confidence, which in turn just leads to overall success in math! Glad we've been able to help her out :)
Excellent presentation, follow up and caring, always checking on how things are going with close follow up, very accommodative with great learning experience, we feel significant difference in the way our children see Math compared to others who don't go there, in addition, they not only grow relation to Math but also deep love with the subject and they tend to enjoy it, I believe it is worth every cent.
