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.

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.
