    About Mr. TK

    A teacher in your student’s corner.

    I’m TK, founder of TK Math Academy. I help students turn confusing math into clear reasoning—and learn to take the next step independently.

    I’m a certified math teacher with a degree in Applied Mathematics from UC Berkeley, a Master’s in Education, and over 15 years of teaching and tutoring experience.

    15+ yearsTeaching and tutoring experience

    My approach

    Understanding comes before shortcuts.

    I look for the exact point where understanding breaks down. Then we rebuild it with a clear explanation, purposeful practice, and a chance for the student to explain the reasoning back to me.

    My experience spans classroom teaching, individual tutoring, and competition coaching, including work with Art of Problem Solving, ACE Academy, CL Academy, C2 Education, and Summit Charter School.

    Whether we’re reviewing Algebra 1 or preparing for AIME, the goal is the same: a student who can explain the method, recognize when to use it, and check whether the answer makes sense.

    What I want students to ask

    “Why does this work?”

    A correct answer matters. Understanding how to reach it—and how to spot a mistake—is what makes the next problem more manageable.

    How it works

    Inside a lesson.

    01

    Make the thinking visible

    We work through the setup and reasoning, not just the final answer.

    02

    Use the error as a clue

    A mistake helps us decide whether to revisit a concept, an algebra step, or the approach.

    03

    Try the next one independently

    The student applies the idea and explains the steps, with support adjusted as needed.

    Student & parent voices

    Clear explanations.
    Patient support.

    From classroom foundations to competition math, students and parents share what made a difference in their lessons.

    Calculus BC

    From C+ to A.

    “He was also really good at catching my mistakes, and as a result my grade went from a C+ to an A! I am super grateful for this tutor and I highly recommend him for anyone looking for a calculus BC tutor.”
