About Sarah
High school students aiming for elite math competitions often find themselves hitting a wall despite long hours of study. Sitting at my desk at Caltech, I realized that true problem solving requires dissecting the mechanics behind the numbers. I hold a PhD in Chemical Engineering and have spent 10 years working in defense contracting.
My engineering career ended in 2022, and I now apply that rigor to teaching. Complex proofs should be simple. I focus on mental math, geometry, and linear algebra strategies to build a solid foundation. My background provides the analytical structure that students need to excel in exam preparation.

Getting lost in the middle of a calculus derivation is a common frustration that slows down progress for many advanced learners. It often feels like the steps are disconnected until someone highlights the underlying logic of the movement.
During our time together, I share concept maps for every chapter to ensure the material stays organized and logical. We explore mensuration and homework help by breaking down massive problems into manageable variables that reflect real world engineering context. My approach centers on clarity and helping you see the relationships between different mathematical concepts so the flow remains intuitive throughout our work.
