Sarah Williamson, Center Director
Sarah's enthusiasm for Mathnasium comes from her passion for the intersection of mathematics and community. She has over nine years of experience tutoring and teaching STEM subjects at the K-12, collegiate, and adult learning levels. She previously worked for five years as a software developer and android platform analyst for the private industry and as a technical instructor within the public sector in Washington DC. Along the way, Sarah discovered Mathnasium and began working evenings as an instructor for three years, where she realized how impactful Mathnasium could be. With her move to the West Coast, she made the transition into Education full-time as the Center Director of Mathnasium of Redwood City. She is proud to be serving the Redwood City community. She believes Mathnasium is where bright futures are imagined and truly realized.
Sarah completed her engineering degree in Computer Science and Mathematics at Virginia Tech, with a focus on Communication Technology and Gender Studies.

Cora Sum, Assistant Center Director
Cora has a huge passion in the Education field and in working with children. Cora believes every student is unique and is capable of learning!

Ellen, Curriculum Manager
Ellen brings her love of tutoring and learning to Mathnasium. As a regular chemistry tutor, she has seen firsthand how students can be held back by a lack of confidence in math. This fires her passion for tutoring math. She loves watching students gain confidence in school subjects and particularly believes that advancing in math helps students advance in life.
Ellen has a Ph.D. in Chemistry from the University of Illinois and worked in New Zealand and Singapore, before settling in the Bay Area. Currently, she is pursuing an MBA at Santa Clara University and relaxes by swimming laps and going for long walks.
Beatrice Chan, Owner/Managing Director
Beatrice earned her degree at the University of Illinois, Urbana-Champaign in East Asian Languages and Cultures with a Minor in Business. After earning her degree, Beatrice moved to Silicon Valley in 2001 and worked for 9 years as an Account Manager and Program Manager with startup companies that had a strong presence in the Education market.During that time, Beatrice was heavily involved with Healthy Cities Tutoring of San Carlos, teaching children before work. Realizing that there was a severe need for math enrichment, she soon after ventured on her own to tutor Math all around Redwood City and San Carlos. Her ability to help children understand the concepts of math and the demand for her services is what prompted Beatrice to open up a Mathnasium Center.
Beatrice is passionate about making children knowledgeable and successful in understanding Mathematical concepts, all while having fun! She believes that being fluent in Math not only boosts a child's confidence, but also empowers them to reach their fullest potential. This passion is what drives her to be a proud member of the Mathnasium Family.
