Our Team

Our specially trained math instructors will teach your child how to understand math in an individual setting; our unique approach enables us to explain concepts really well and lend a helping hand to every student. Our tutors foster a caring, encouraging environment that helps kids thrive and learn! Read below to learn more about our talented team:

Matt Cleary, Regional Director


Matt is customer service driven and has always loved mathematics. Starting as an engineer at Penn State University, Matt eventually graduated with a degree in Finance from the University of Maryland. The desire to help "math make sense to kids" is what brought him to Mathnasium in the first place. Matt offers outstanding consultative advice to educate parents and students on the Mathnasium program and the academic expectations of kids today. Knowing success breeds success, Matt's team will help design a learning plan just right for each student so they can meet their math goals in an efficient manner.

Matt is currently the Center Director at Mathnasium of West Chester, and also helps out the Mathnasium of Glen Mills families. 


  Joe Miller, Director of Operations

Joe has been working for Mathnasium for over 6 years and oversees operations of 7 different Mathnasium locations including Glen Mills. He has a passion for helping students become the best math students they can be. The pride in watching students grow in their math ability and gain confidence in themselves is what drives him every day. A proud alumnus of the University of Maryland, College Park with a BA in Communication, he has extensive experience working with kids in the past at both Walt Disney World and the Bowie Baysox. A lifelong fan of math, Joe loves teaching students while having fun at the same time and excels at relating to students. 


 Larry Martinek, Creator of the Mathnasium Method

Larry has spent his entire career finding a better way to teach math. From inner city 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 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 curriculas ever produced for teaching math.

While Larry is not an Instructor at our Center, he is a valuable asset we can call on to ask about specific students' scenarios for guidance and advice. This has helped to make visits more productive and enjoyable for many of our students.
