Sarah Yoon
Owner & Center Director

Hello, my name is Sarah and I’m the Owner and Center Director of Mathnasium of North Beverly, one of the top math learning center locations in the world.

I began my career with Mathnasium several years ago as an Instructor, applying my passion for teaching, mathematics, and helping others towards my work with students and collaborations with local educators and schools in the community.

The creator of Mathnasium's curriculum, Larry Martinek, is an insightful math instructor who has "broken the code" for teaching math in a simple way that makes sense to everyone. As Larry often says, "Showing a student that they can succeed in math can change the course of his/her life". Through Mathnasium, our Instructors learn many incredible approaches and techniques for tailoring lessons to a particular student's way of thinking. The underlying math is the same, but how it is presented is terrific in its simplicity and elegance – to put it simply, we make math make sense!

Mathnasium of North Beverly is a bright, open, and fun location where our caring and engaging Instructors help students of all ages come to catch up, keep up, or get ahead in math. We also offer standardized test prep for the SAT, PSAT, ACT and high school or private school placement exams such as the SSAT, ISEE, and HSPT.  Prize cabinets, raffles, student rewards, the Annual TriMathlon, Math Nights co-hosted with local schools, and other events – in addition to an excellent teaching staff that specialize in math – make our center a place kids love to come to.  We hope you will visit our center or contact us to learn how we can transform your child’s life.
