  Steve Ruiter, Center Director 

Steve is the Center Director at Mathnasium of Shoreline. Prior to opening his Mathnasium center, Steve worked as Director of Systems and Programming with Milliman, specializing in building systems tools for pension actuaries. Steve is a Fellow of the Society of Actuaries. He has an MS in Appled Mathematics from Georgia Tech and a BS in Mathematics and Computer Science from Calvin College. Steve has loved math his whole life and is enthusiastic about helping every child in the Shoreline area to truly understand math by teaching it in the way that makes sense to them. Also as a lifelong competitive swimmer, he is excited to be opening up his center next door to Goldfish Swim Academy. Steve has been involved with Shoreline Math Olympiad since his oldest son was in fourth grade in 2004 (that son is now working on a math PhD), and Steve is excited to bring the Mathnasium Method to the children in the community. 




Craig Huber, Instructor

Craig has spent all of his adult life working to help others understand and enjoy mathematics. He began by tutoring family and friends in high school, and then in college made his way to tutoring at the University of Florida’s Teaching Center. He tutored there while he was a student, received his BS in Mathematics and Physics, and eventually became the Coordinator of the center. He continued on to earn his Master’s in Mathematics Education. Craig moved to Seattle and is now an associate professor at North Seattle College, Shoreline Community College, and Seattle University. He loves showing students useful, interesting, and impactful ways that math is used every day. He is excited to extend his experience to younger students and help give perspective and context for students’ future courses, degrees, and careers.
