My daughter loves mathnasium and the staff!
Caring and attentive staff! Our daughter loves it!
My daughter who was not doing well in math lost her confidence and begin to not like school. 1 month in at Mathnasium and she is enjoying math more. Waiting for it to reflect in her grades, as it has only been 1 month.
Mrs. Castillo, the director of Copperfield center, is very compassionate and attentive. All the tutors seem to be very acknowledged. My daughter really enjoys going there and cannot wait to master her math skills. All the tutors utilize positive reinforcements to help children to gain their confidences in Math. I've seen the differences in my daughter even though she's there only 2 months. I can't wait to see her blossom more.
My son improve his grade in Math with the help of people in Mathnasium.
My daughter is very excited. This is the second summer we are doing Mathinasium. My daughter loves the fact that she starts the next grades work now. Awesome
My son is happy with the tutorials and loves the learning environment.
Flexible scheduling. Yolanda Castillo is great and passionate about learning and making sure children achieve their goals.
They make the process easy for parents.
My 10 yro son hated math. He had wonderful teachers at school but was not "getting it". I then tried to teach him how I learned hoping less steps would encourage him. This only added to his frustration and even to the point of him giving up. He would make a 70 on a test and tell me, "at least I passed". My son is a bright child so I knew he had potential to do better than that. My husband and I enrolled him in Mathnasium and now he is TRULY excited to learn. His grades improved and he has more self confidence. Ms Yoalnda and all the wonderful staff at Copperfield location are AMAZING!! They are so helpful and patient I wish we enrolled him sooner! 🤗

Our daughter was struggling with math. She has made improvement, now is doing better.
My daughter is getting more comfortable with math. I also like the fact that they help with homework.
The instructor I frequent is the greatest. Being the oldest student at the center is very humiliating at times but her reassurance and guidance helps me push through focusing on the main objective. Ms. Yolanda is by far a real educator dedicated to helping you reach your goals.
