Owner/Center DirectorBruce Withycombe, Owner/Center Director

By owning a Mathnasium franchise, Bruce has come full circle back to the joy of mathematics and problem solving that lead him to earn a Bachelor of Arts in Mathematics from Lewis & Clark College. In addition to studying Math while in college, Bruce played Varsity Football, earned extra money as a Math Tutor and was involved with student politics. After graduation he studied Actuarial Science at Georgia State University and began a career in the Pension and Retirement Plans Industry, working with consulting firms and insurance companies in that capacity. An opportunity to work in healthcare consulting moved Bruce into the Health Services Industry, where he most recently worked with WebMD Health Services as National Account Manager. Outside of Mathnasium, Bruce has 3 school aged children, which keeps things very busy with school, music, and athletic events.

Bruce has spent many seasons as a youth basketball coach, and in his spare time works as a musician, playing in multiple bands in the Portland area including Ural Thomas & The Pain  ( , Jujuba (, the Goodfoot All-Stars and the WayDowns (  Bruce is a member of The Portland Horns, who have played with national touring acts such as The Decemberists, The Violent Femmes, Spoon, Bobby Bare Jr, The Next Waltz and many others.  His discography includes credits with Jujuba, Kathy Walker Band, The Decemberists, NRVS LVRS, Jerry Joseph & the Jackmormons, Casey Neil & the Norway Rats, Point Juncture WA, Kory Quinn and a host of others.

Noah Gribben, Center Director

Noah graduated from Northwestern University in 2004 with a degree in theater. He also attended the University of Alabama Birmingham for studies in higher mathematics. He has spent time performing as a professional mime, working on whale watching boats, teaching yoga, writing math content and tutoring students all over the country. He has a passion for teaching, especially mathematics. All students deserve patience, empathy and understanding, and there is nothing quite like seeing a student's eyes brighten as the light of understanding flips on.

Traveling the US is also a passion for Noah. He has driven to and through every state in the country save for Hawaii (on his bucket list) and loves a good road trip. In his free time Noah enjoys spending time with friends and family, playing guitar/mandolin/ukulele/piano, ultimate frisbee, frisbee golf, and relearning Calculus.
