My Teaching Philosophy

Learning mathematics should feel like assembling a puzzle—not reading an encyclopedia. By breaking mathematics into small, connected ideas, students gain confidence quickly. Whether you're preparing for the SAT or your first actuarial exam, the goal is understanding, not memorization.
