In that capacity, Ilan was responsible for the supervision of staff and students, professional development, curricular development, and academic performance, among other responsibilities.

When not at Mathnasium, Ilan can often be found running in preparation for a marathon or some other race, usually for charity. Ilan is a Boston Qualifier, and Abbott World Marathon Majors Age Group World Championships qualifier! As passionate as Ilan is about running, he is more passionate about education, and about math education and critical thinking in particular. For Ilan, Mathnasium is the perfect blend of formal and informal learning, and he loves being a part of the Mathnasium team!

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.
