Hello! My name is Evan Skog, Center Director at Mathnasium. After five years in restaurant management, I returned to my true passion—helping students experience “Aha!” moments in math. I believe math, like any skill, improves with practice, and I love showing students they can succeed.
I originally studied Percussion at UNC Greeley but switched to Math after realizing my passion for education. Outside of Mathnasium, I enjoy composing music, reading, playing board games, and exploring the Rockies. I’m excited to help students build confidence and discover the joy of learning!
Originally from Peru and raised in Connecticut, I’m currently a PhD student in neuroscience at CU Anschutz. When I’m not studying, I enjoy knitting, crocheting, and playing The Sims 4—my goal is to collect every pack so I can build the cutest homes!
I love teaching at Mathnasium and find it incredibly rewarding to see students grow in their math skills. My favorite number is 2 (mostly because it just makes sense to me, and I like writing it fancy). Fun fact: I own two snakes! In five years, I hope to be defending my PhD thesis.

In elementary school I helped run the Math Olympiad team, In middle school I took advanced math classes and studied on the side, and in high school so far I've taken the hardest classes I can. Apart from loving math, I play Ultimate Frisbee, run Cross Country, and absolutely love to play music (mainly piano and saxophone, but I've been trying to learn the drums recently as well). In my free time I like to spend quality time with friends and family.

I love when I get to see that Aha moment that happens when a student finally understands something they've been struggling with.

In 5 years I'll be... I will be a senior in College hopefully close to obtaining a degree that I'm excited about and ready to continue my life after college.
