Our staff is built to teach each student individually, to develop the skills they need to thrive in mathematics, and to foster a love of learning.

Matt Karstens

Curriculum Coordinator

After graduating from Baylor, Matt went on to Sewanee and UTC to earn his Bachelor's and Master's Degree in mathematics. Matt has been working at Mathnasium since 2017 and loves his job - to unlock the mysteries of mathematics for students who far too often have believed they might never understand. In addition to teaching, Matt is responsible for overseeing the learning plans of all students so that they are balancing the dual objectives of getting caught up while also staying on top of current coursework. In Matt's free time, he enjoys inventing games that illustrate mathematical concepts for students, sharing recreational math puzzles with coworkers, and writing.

Marybeth Guppy

Education Director

Marybeth has a Bachelor's degree in Elementary Education from Georgia Southern University. Before "marrying in" to Mathnasium in 2020, she taught kindergarten and 2nd grade. Marybeth trains and coaches all Mathnasium instructors. It is one thing to be good at math yourself, but it is another to be able to communicate math concepts to students in a way that makes sense to them. Not only does this require exceptional understanding of the content, it also requires that tutors be able to form relationships with students so that they are more inclined to listen and to trust them. Beth's true joy is to coach new instructors to ensure they are able to be their best for our students - she is very proud of the fact that many of our instructors go on to become teachers themselves after discovering the joy of teaching at Mathnasium.

Ben Craig

Instructor

Ben Craig is passionate about the topic of math and finds the experience of working with peers, by either teaching or learning together, to be the most exciting part of understanding both the paper concepts and the physical world application of math. Graduating from STEM School Chattanooga and attending Chattanooga State Community College, Ben is becoming an expert in the field of computer science and believes that the fundamental basis of computer logic starts with understanding of mathematics.

Ruthann Hartman

Jonathon Brackett

By day, Jonathon works in a materials laboratory for a utilities company, bringing a practical, real-world understanding of science and math to his tutoring sessions.

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.
