Meredith Jones, Center Director
Meredith Jones and her husband live in Roanoke. Her two greatest passions are math and their dog, Sam. Meredith studied Meteorology at the University of Oklahoma for two years, and then decided to earn her degree in Mathematics in order to teach. She has taught 9th Grade Algebra I and tutored for many years.

Meredith is overjoyed to have the opportunity to share her passion with children of all ages. She loves explaining why things work the way they work and boosting every child’s self-confidence. She feels so blessed to have a job that she is so passionate about.

We are here to develop a child’s number sense and fluency; we will never answer a question with, “because I said so.”

Brian Pullen, Lead Instructor

He has a bachelor’s degree in Mathematics Education from Northland International University and has experience teaching math from 5th grade to 12th grade.

When not at the center, Brian loves to spend time with his wife and son. He also enjoys playing soccer, working Sudoku puzzles, and watching movies and JEOPARDY!. His goal is to honor God in all that he does, pressing on for the Lord through life.

“Know ye not that they which run in a race run all, but one receiveth the prize? So run, that ye may obtain. And every man that striveth for the mastery is temperate in all things. Now they do it to obtain a corruptible crown; but we an incorruptible. I therefore so run, not as uncertainly; so fight I, not as one that beateth the air: But I keep under my body, and bring it into subjection: lest that by any means, when I have preached to others, I myself should be a castaway.” --1 Corinthians 9:24-27

Rick Mauderer, Instructor

He and his wife have a 18 year old college student who loves his drum set, and a 17 year old junior who loves her French Horn (although he could swear it has a German accent to it!!) He remembers sitting in 9th grade Algebra class in a small town in Iowa looking at his Math teacher/Football Coach, thinking, “How can such a cool guy end up being a math teacher??” He then went on to earn a degree in chemistry with minors in physics and – you guessed it – MATH! He has taught high school physics, geometry, algebra, algebra 2, chemistry, environmental science, and physical science. He also teaches rock climbing and repelling, loves to scuba dive, and do a host of other fun and cool stuff.

Along the way, Rick has helped to direct a Christian adventure camp in Wyoming, having played guitar for over 40 years – even professionally, and being in a band voted best band in Tarrant County by the Star Telegram readers in 1999-2000. He has also been a youth and worship pastor, and is now a high school assistant principal turned district coordinator of technical projects. He is nearly finished with his PhD in Curriculum and Instruction, and will have a minor in statistics.
