Mark Minio
Instructor
Hi, my name is Mark! I graduated from Iona University with a Bachelor's in Mathematics, and a particular area of interest in Game Theory. I have always found math to be engaging, and I strongly believe that skill in math is a result of practice and patience. It is my hope that I will be able to share my passion for math with students, and help them see how compelling the subject really can be.
Matilda Fu
Instructor
Hi, I'm Matilda, and I use any pronouns. I have a passion for hiking, reading, and math. I majored in philosophy in college, and for the past three summers, I’ve tutored children aged 8-17 in subjects like writing, math, history, and piano. I joined Mathnasium because I truly miss teaching and working with kids. Helping children not only understand but also enjoy math brings me a deep sense of fulfillment. I can relate to the struggles some students face—back in high school, I had a hard time with math myself and didn’t have a tutor. Through trial and error, though, I figured it out and discovered strategies that worked for me. From my teaching experience, I’m confident that with the right approach, any child can master any subject.
Thomas Molyneaux

Hello everyone! My name is Thomas Molyneaux, a mathematics and coding enthusiast! I am a graduate of Stamford High School, and it was there were I found my love for math through their math team, and I want to help others experience math in a fun and rewarding way as well. Currently, I will be attending UConn Stamford with the intention of pursuing Software Engineering. I have tutored before in English, mechanics, and science, where I discovered my passion for working with others to improve their academic skills; however, Mathnasium combines my passion for both tutoring and mathematics all in one. I hope to help students become incredible math experts while working with Mathnasium!
