My daughter really enjoys going to Mathnasium to be tutored, she is so much more confident about math.
The tutors are excellent and this program makes math simpler and fun.
Lenny works with our schedule and makes an effort to accommodate us. She also has made it a point to assign Timothy the instructor he's made most improvement since he started. My son tells me he enjoys learning and feels comfortable to ask any question without feeling embarrassed. Lenny also works to incorporate math my son is being taught in school, since he's behind and they are trying to get him caught up. Really good place. Feel safe to leave my son and also friendly and professional staff.

Sofia has made significant progress with Mathnasium this year. We felt it was important to attend the program during the summer because we felt like she will be far more prepared for entering the fourth grade. The teachers in Mathnasium are able to explain the concepts better than teachers at the elementary school. Sa
