Why do I coach?
I am passionate about interacting with students and professionals and helping them navigate complex problems. There is a unique thrill in witnessing a student's breakthrough - the exact moment when a difficult concept finally "clicks" is a powerful motivator. I started coaching because I wanted to change how students approach math - from a formula oriented approach to a more logical, first-principles approach that answers "why" something works. I also welcome the challenge of advanced, unexpected questions that students often ask as they provide me the perfect opportunity to demonstrate the power of logical problem-solving.
