Max Nuckols

District Manager

Hi! I’m Max. I’ve been with Mathnasium since 2019 when I started as an instructor as a high school senior. When I graduated, I went to NYU for two years to study biochemistry, but later decided to come home and change my major to Business Administration. I’m currently working full time at Mathnasium while attending classes part time at Cal Poly Pomona to finish my degree. I love what we do here because the idea of making math fun for kids is such a unique philosophy, and it’s something I resonate with a lot because I love to learn. In my own time, I’m a huge nerd for science, history, sci-fi, fantasy, superheroes, and more, and once you get me started, I could talk for hours about these things. I also enjoy outdoor activities, and even built a skimboard out of plywood a couple years ago so I could learn to ride it at the beach. If you see me in the center at any point, don’t be afraid to say hi!

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.
