What do you like most about learning?
I love the feeling when all your hard work pays off and something that once felt really challenging suddenly feels easy!
What is the biggest impact you’ve had on a student’s ability to become proficient in math?
I have had the pleasure of watching so many students grow in their confidence in math. It’s incredibly rewarding to see their entire math journey—from their first visit, when they may feel unsure of themselves and math feels like a burden weighing on them, to each visit that follows. Little by little, they chip away at their fear of math and begin to build confidence in themselves and their abilities. Seeing their hard work reflected in their performance, both at school and at Mathnasium, is one of the most rewarding parts of what I do.
What type of math do you enjoy teaching most?
Numerical fluency
How do you make learning math fun for students?
I make learning math fun by connecting concepts to real-world applications that reflect each student’s unique interests. By showing students how math relates to the things they already enjoy and care about, I help make learning feel more meaningful, exciting, and relevant to them.
