About Me
I hold a Master's degree in Mathematics from UC Berkeley, and I bring that same rigor and love of problem-solving to every subject I teach — math, chess, and Hebrew.
Math: My graduate training gives me a deep, structural understanding of mathematics, from foundational arithmetic and algebra through calculus and beyond. I'm comfortable teaching across a wide range of levels, whether that's helping a middle schooler build confidence with fractions or working through proof-based concepts with a high schooler headed toward AP Calculus or beyond. I focus on building genuine understanding rather than rote memorization, so students leave each session able to reason through new problems on their own.
Chess: I've spent years coaching players informally, helping them move from knowing the rules to actually thinking strategically — recognizing patterns, planning several moves ahead, and learning from their own games. I enjoy working with students who are just starting out as well as those who already play casually and want to sharpen their tactics and opening understanding.
Hebrew: As a native/fluent Hebrew speaker, I teach the language the way it's actually used — natural rhythm, real vocabulary, and practical conversation — while also being able to support students working through more structured or textbook-based learning goals.
My ideal student is curious and willing to engage actively, whether they're a child building foundational skills, a teenager tackling more advanced material, or an adult picking up a new interest. I tailor my approach to each person: some students thrive with structure and steady repetition, others learn best through open-ended problem-solving or conversation. What I offer across all three subjects is patience, clear explanations, and a genuine interest in seeing students think for themselves rather than just follow steps.
