Michael Williams

Lead Instructor
Michael is from a rural town off the coast of Northern California. As a 2021 graduate from a local junior college, his expertise lies within the world of mathematics. Along with an Associate's degree in Mathematics and another in science exploration, Michael graduated in the uppermost strata with honors. His belief is that everyone should give themselves a second chance; with his mathematical prowess and tutoring experience he hopes to change the way students look at math and themselves. If there's anything he's learned in his year with Mathnasium, it's that kids aren't bad at math, they just need someone to cheer them on.

Brooks Franklin

Administrative Assistant
Brooks grew up in La Quinta, California and has previously worked in retail stores and in computer / electronic repair. He joined the Foster City Mathnasium team in early 2018. Starting to work as an instructor, he could very quickly see the impact that Mathnasium had on its students. Towards the end of 2019 he was promoted to an administrative role and with that new perspective he continued to see the benefits of the Mathnasium program. In addition to this, his new role had allowed multiple opportunities for him to learn new skills and gain experience working with new projects. His favorite parts of the job are organizing data collected from student sessions and creating and optimizing processes to make everyone’s job easier and / or more efficient.

Bryan Vo

Administrative Assistant
Bryan studied Economics at the University of Southern California, but his secret is that his real passion lies in education and analyzing literature. He loves his Mathnasium coworkers and enjoys supporting the moderators in both classrooms. His favorite part of the job is finding the gap in a student’s knowledge and using his skills on the job to fill in that gap. “There’s nothing more satisfying than seeing a passing score on a student’s assessment”, he thinks, in a recent moment of introspection. He believes that it is not about what concepts a student gets wrong on a test, it’s about why and how they got it wrong.

Neha's love for math grew from a geometry teacher that instilled confidence in her.
