I am an upper school mathematics teacher at St. Stephen's & St. Agnes School, an independent K-12 college preparatory school in Alexandria, Virginia (located in the Washington, D.C. metropolitan area).

I currently teach Geometry 9, Advanced Algebra II/Trigonometry, and Number Theory, in addition to serving as a ninth grade class dean.

Outside of school hours, I work as a private math tutor. I have experience tutoring Algebra I, Geometry, Algebra II, Precalculus, and college-level Calculus. This includes advanced and honors-level tracks of these courses.
