A pharmacist by profession, I know that math is very important in every child's life. Math education provides the foundation that is a stepping stone for ongoing success in life! The Mathnasium Method is very structured, yet it nurtures every child and finds a way to make learning fun! I strongly believe Mathnasium provides a wonderful way of learning math where every child has an awesome experience and develops the confidence necessary for future success.
