Hello, my name is Grace Peng and I am the Managing Center Director here at Mathnasium of Foothill Ranch. Each day, I make it my goal to ensure that students have an effective, engaging and encouraging learning experience that cultivates an intuitive understanding of math. I look forward to working with you and your student to help build a successful future for your child.
