CenterDirectorChris Johnson, Owner and Center Director 

I have worked for the past 20 years in education as a teacher, administrator and consultant. I am thrilled to bring Mathnasium to the Beaverton and Tigard area. We want everyone to LOVE math as much as we do. I am interested in seeing results from our students and Mathnasium gets results! Having spent the last 4 years working as a Mathnasium center director, I have seen the impact our program can have on the lives of students. We welcome you to come in anytime and see our center in action!

CenterDirectorLarry Martinek

Chief Instructional Officer, Developer of Mathnasium Program. 

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 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.
