Hans Kellner

Hans Kellner grew up in central New York, hopped over to Arizona for high school and college, and then to the San Francisco Bay Area.  He calls these moves the ‘too cold’, ‘too hot’, and ‘just right’ transitions. It was in Arizona he began mountain biking and then racing.  He was an early member of ORBA (Off Road Bicyclist of Arizona) and later NORBA.  A job opportunity in Marin County brought him to California and to the birthplace of mountain biking.  Since then he has excelled in his work life as well as his cycling.  Around 2007 he was asked by friends involved with the Berkeley High MTB team to assist in coaching.  Thus began the still ongoing commitment to being an assistant coach with the team.  Besides cycling, Hans also enjoys taking photographs, creating short films, trying new foods, and challenging himself by learning new things (ask him about becoming a CNC Shop Master).

Jon Francis

Jon grew up in the Sonoma Valley, where he traveled the network of farm roads on classic bikes like a green Schwinn Stingray and red Schwinn Varsity. While studying Electrical Engineering at CU Boulder, he relieved stress by road riding in the eastern plains and Rocky Mountain foothills. Back in the Bay Area, he acquired his first Stumpjumper in 1994 and with it a love of hill climbs, setting out from his Inner Richmond flat to tackle Mt. Tam or find more circuitous routes to the SOMA studio where he worked as a film and video editor. Becoming a husband and father of two, and forming Idle Hands Studio, a Marin-based animation company, put a long hiatus in his riding. Then in 2010 he was conscripted as a ride leader for the San Rafael Bike Dawgs, and was handed the keys to the team in 2011. In 4+ years as head coach he’s discovered many things, not the least of which is that happiness comes from helping others, and no amount of time spent helping kids is ever wasted. Joining the NorCal rules committee in 2013, and the NorCal Board in 2014, he’s eager to help bring high school cycling to young bikers whose schools still don’t have teams, and ensure that all high school riders have a safe, fair, productive, and fun environment to become better cyclists, racers, and people.
