Jennifer Sanders, Secretary

Jennifer has been road and mountain biking for over 20 years and during her few years racing has made podium in both  downhill and cross-country races (Downieville), as well as in Xterra triathalons.    An alumni of Berkeley High School (pre- any mountain biking teams) she believes Nor Cal/ NICA are a great organization and opportunity for the students.    She lives in San Francisco where she is an attorney for Nickelodeon’s online games division focusing on intellectual property and privacy (she has also worked for  Sun Microsystems, Veritas Inc., BEA Systems, and Oracle).   Last summer’s cycling adventure was a week  long trip downhilling in Morzine (Switzerland and France) and the previous year a week cycling along the Tour de France.


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.


Christina Toms

Christina is an environmental engineer with the San Francisco Bay Regional Water Quality Control Board, where she specializes in the protection and restoration of creeks, wetlands, and estuaries. A native of the New Jersey Pine Barrens, she first learned about the natural world through long bike rides and horseback rides on the trails in the forest behind her childhood home. After earning a BS in Biological Resources Engineering from the University of Maryland, she moved cross-country to earn an MS in Civil and Environmental Engineering from UC Berkeley. Her now-husband Brian (who provides neutral support at all NorCal races) introduced her to the League over 5 years ago, and ever since then Christina has been a member of the race crew and a coach at the winter clinics. An avid mountain biker and less-avid road cyclist, she lives with Brian and their pets in Fairfax, where she can’t believe she gets to ride the same famous trails (and meet the same famous founders of mountain biking!) she read about in high school. Along with the NorCal League, Christina provides volunteer science and engineering support to a range of local non-profits, including the Marin County Bicycle Coalition, Marin Conservation League, and the Tamalpais Lands Collaborative.
