Janet Escano

After all, it’s more enjoyable to think together than to struggle alone.

Samantha Bents

Instructor
Sam graduated from Princeton University in 2022 with a degree in Ecology and Evolutionary Biology and a minor in Global Health and Health Policy. But math has always been at the core of what Sam does. She was a state-level math team competitor in high school and it was a vital part of her college curriculum. Now, she uses mathematical modeling to study epidemiology at the National Institutes of Health. Sam tutors at Mathnasium because she believes math can take people to great places. She wants to help our students get there!

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.
