Biography
My love for teaching began while I was tutoring in college and seeing students realize that mathematics could make sense to them. Those moments inspired me and continue to shape the way I teach today. As a mathematics instructor and educator at City College, I try to share with my students the same joy and satisfaction I find in problem solving, while helping them see how mathematics can empower them in both school and life.
