Students/Parents: Thank you for considering me as you tutor. I have over 7-years of experience providing top-of-the-line service for hundreds of students taking college level mathematics, and physics. I have a Bachelor’s of Science in Mathematics with an emphasis of pure math, and am currently in graduate school for mathematics. I love to explain complex information, and am able to do this in a simple fashion that students respond to very quickly.
