Our staff is built to teach each student individually, to develop the skills they need to thrive in mathematics, and to foster a love of learning.

Hector Diaz

Hector graduated from the University of Portland in 2021 with a major in mathematics. He has experience working with children of various ages and backgrounds. He loves math and understands the struggle a lot of students deal with as math was difficult for him over the years. Through his struggles, his goal is to make math less intimidating and more fun by addressing students' needs while making them feel understood and less alone. On his free time, he enjoys playing music as well as exploring the outdoors.

Our Mathnasium Mission

Teach children math so they understand it, master it, and love it. Math can change their lives, and they can change the world.

What I love about Mathnasium is the ability to teach problem-solving skills and make math make sense, while also making a student smile.
