Zoe Reckas

Advocacy Assistant

Zoë joined MCBC in the Fall of 2022 as MCBC’s Advocacy Assistant helping our Policy & Planning Director with our newest programs – E-Bike Smart Marin and Local Teams.

Growing up on the Monterey Peninsula her default mode of transportation was walking and biking, which was partly thanks to the inherent bike-friendly nature of her hometown as well as the influence of her father, who refused to drive anywhere within a 15 mile radius. With roots as a commuter cyclist, Zoë became interested in bike camping/touring during her time at Sonoma State where she earned her B.S. in Kinesiology with a minor in Environmental Science and Planning.

She hopes to transform more cities into havens for cyclists and pedestrians, so that others may enjoy the many benefits of human-centric communities. Contact Zoe
