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.

Larry Martinek

Creator of the Mathnasium Method
Larry has spent his entire career finding a better way to teach math. From inner city to public schools, to acclaimed magnet schools, to leading private and parochial schools, Larry has served as both a classroom teacher and as an educational consultant. He has designed curriculum, teaching strategies, and teaching materials designed to help students and teachers learn math more effectively, He has trained teachers in the art and science of boosting students' ability to "do" math, thereby increasing students' math scores and feeling of self-worth. Larry is the developer of Mathnasium's educational program - one of the most comprehensive and innovative curricula ever produced for teaching math. While Larry is not an instructor at our center in Lake St. Louis, he is a valuable asset and we can call on him to ask specific student's scenarios for guidance and advice.

Rayna Classen

Ms. Rayna Classen is a student at St. Charles Community College and is studying Biochemistry. She hopes to pursue a career in scientific research. Rayna also enjoys making music, writing, and stargazing. One fun fact about Rayna is that she collects rocks! Her favorite number is 33 because it is the atomic number of her favorite element on the periodic table. Her favorite math joke is: What do math teachers and the Backstreet Boys have in common? They both want you to tell them y!

Andy Basford

Mr. Andy Basford started working as an in-store locksmith after his tour of duty in the US Navy. Then, he went back to school and discovered that his knack for mathematics not only helped him in locksmithing but also helped him understand things like iterations and statistics. He holds a degree in Mathematical Science from Maryville University, and his favorite number is φ (because it’s pretty much the same if you subtract it from 1 or invert it to 1/φ). Andy's flair for dad jokes, however, seem to be rather pun-ishing. One time, Andy submitted 10 puns to a dad joke contest, figuring that at least one of them would have a chance to win, but unfortunately no pun in 10 did.

Milo Weston

In his free time, Milo loves to play tennis, create fine art, and study Japanese; he’s been learning for a little over three years. He also loves spending time with his younger siblings and golden retriever. Milo’s favorite number is 8 because it represents victory and balance. It is also a symbol of prosperity in Chinese culture.

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.
