Sarah Yoon
Owner & Center Director

Sarah began her career in education ten years ago as an elementary through high school math tutor. Utilizing her degree in Mathematics, she culminated experience working with students of all levels and subjects, including standardized test prep such as the SAT and ACT, before finding her calling at Mathnasium in 2016. Ever since, she has applied her passion for education, mathematics, and helping others towards her work with kids and fellow educators in the North Shore. In fact, when she's not in the center each day, you can find her at Endicott College, teaching math courses for educators. 

Rather than emphasizing rote memorization, Sarah believes in teaching math in a meaningful way that develops kids' number sense and mathematical maturity, as well as building individualized and comprehensive curriculums for each student that allows Mathnasium to meet kids where they are. She believes that good grades are just a byproduct of what Mathnasium does for kids – when math makes sense, excitement grows, grades improve, and doors open!

Established in 2011, Mathnasium of North Beverly is a bright, open, and fun learning environment where caring and engaging Instructors help students of all ages come to catch up, keep up, or get ahead in math. Mathnasium also offers 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 making math fun for kids – make our center a place kids love to come to.
