Previously, she supported effective implementation with teachers, specialists, and administrators for 4 years throughout 25 elementary schools in the Hillsboro School District.
The Math Learning Center is fortunate to have a dedicated team of volunteer board members that together bring deep experience in education and the teaching and learning of mathematics.
Steve Burt, Chair
Steve is currently the Director of Strategy for Clarity Innovations, an Oregon-based ed-tech professional services firm. He oversees development of new solutions for Clarity's clients which typically involves blending research-based practices with emerging technologies. Right now, he's paying attention to the education potential of new learning technologies as well as how changes in digital publishing are impacting the classroom. In working with educators and students for nearly two decades (both as a former high school teacher and principal) he is skilled at understanding a wide variety of technologies and their application to education.
Elizabeth currently serves as the Executive Director of CPM Educational Program, a California nonprofit empowering mathematics students and teachers for grades 6–12 via exemplary curriculum, professional development, and leadership. In addition to being a classroom mathematics teacher for many years, she has also been a CPM author and workshop leader since 1993.
Dr. Rebekah Elliott
An Associate Professor at Oregon State University in Mathematics Education, Rebekah designs, researches, and facilitates professional learning of math teacher candidates, teachers, and leaders to meet ambitious learning goals for diverse students. She had the chance to see the ways in which MLC materials support students’ mathematical reasoning while studying educational reform in Kentucky and while working in her son’s primary math classroom. Prior to graduate school, Rebekah was a high school mathematics teacher in California.
Daniel E. Gossack
A graduate of the University of Oregon with a BA in Mathematics, Dan taught high school mathematics for five years in the Salem-Keizer School District. During this time he was involved in Oregon Mathematics Education Program and was an early adopter of MLC's Math in the Mind's Eye techniques. He is a founder and President of TimeMark Incorporated, a manufacturer of traffic data collection equipment.
Dr. David Moursund
A founding MLC board member, Dave has a doctorate degree in math and taught at the University of Oregon in the Department of Mathematics, the Department of Computer and Information Science, and the College of Education.

Dr. Bill Zahner
Bill is an associate professor in the mathematics department at San Diego State University. He teaches mathematics and mathematics education courses for current and prospective teachers. He is also the associate director of the Center for Research in Mathematics and Science Education at SDSU. Bill's research investigates how teachers can design classroom learning environments so all of their students, including students who are learning English, have an opportunity to learn key mathematical ideas and concepts. Bill's interest in this research area was sparked by his experience teaching high school mathematics for three years in Chuuk, Federated States of Micronesia.
Dr. Eugene Maier
Gene is past president and co-founder of The Math Learning Center, and professor emeritus of mathematical sciences at Portland State University. Earlier in his career he was chair of the department of mathematics at Pacific Lutheran University and later, professor of mathematics at the University of Oregon.
He has a particular interest in visual thinking as it relates to the teaching and learning of mathematics. He's co-author of the Math and the Mind's Eye series and has developed many of the mathematical models and manipulatives that appear in The Math Learning Center materials.
He has directed fourteen projects in mathematics education supported by the National Science Foundation and other agencies, made numerous conference and inservice presentations, and conducted inservice workshops and courses for mathematics teachers throughout the United States and in Tanzania.
A co-founder of The Math Learning Center, Don’s career was devoted to education beginning with his years as a classroom teacher. He believed that all students could find meaning in mathematics, honored their thinking, and understood that learning math was more than memorizing procedures. He shared a passion for improving math education and believed in the power of visual thinking.
After serving as the state math coordinator for Oregon, Don brought his leadership skills to MLC. During his 30 year tenure he was in charge of operations and led the growing organization through several facility changes culminating in the construction of our current warehouse and office space in 1994. A man of many talents, Don designed the entire facility himself and oversaw each aspect of the project. As a tribute to his vision and dedication our building was named in his honor upon his passing in 2010.
