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 students in 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 6 years working as a Mathnasium center director and owner, I have seen the transformative impact our program can have on the lives of students. We welcome you to come in anytime and see our center in action!

Brenna Calmer, Instructor

Brenna is currently a graduate student at Portland State University. While studying to earn a master’s degree in Mathematics, she also teaches an undergraduate math course each term at PSU. A passion for the arts and the sciences led Brenna to complete her undergraduate degree in Dance and Mathematics. She is motivated by the opportunity to show students how fascinating and creative math can be. When she’s not doing math, Brenna can be found taking dance classes or trying a new cake recipe.

Leah Wegner, Instructor

Leah completed her undergraduate degree in computer science and recently received her masters in elementary education from Portland State University. From a young age, she has been enthralled by numbers, patterns, and math in general.  She knits, crochets, and codes in her free time. She is always excited to help students learn just how much fun math can be both as pure math and when applied to other disciplines.

Favorite Math Joke: Why did the math book look so sad? Because it had so many problems.

 

 Jesse Blaha, Lead Instructor

Jesse is a mathematician hipster, who enjoys great coffee, and working on math  problems while drinking coffee. Jesse is currently a Math major at PSU. He has an Associate of Science degree from Portland Community College with a focus in Mathematics. He enjoys working with kids, and spent the past four years teaching swimming at the Conestoga Aquatic Center. Jesse enjoys playing chess, swing dancing, judo, baseball and Brazilian Jiu-Jitsu. 

 

 Sam Schaffer, Lead Instructor

Hailing from the foothills of the Colorado Rockies, Sam grew up as an outdoor enthusiast. With a love of learning equal to his love of nature he was bound for academia. With interest in both music and mathmatics, Sam is currently finishing undergraduate work  in Mathmastics at PSU and PCC with an end goal of Ph.D studies. In his few hours between existential queries, Sam is most likely: practicing yoga, playing an instrument, making coffee or meditating. Namaste!

 

 Jonathan Hyun, Instructor

 Jonathan recently graduated from Oregon State University with a degree in Construction Engineering Management and a minor in Business. Born and raised in Oregon, Jonathan attended Southridge High School before heading south to Corvallis for his studies. With interests in athletics and in math, he hopes to combine these two passions in the future. In his free time, he enjoys supporting the Blazers, playing basketball and traveling. 

 

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.
