Scott has quite a local following with cyclist and skaters looking forward to his return to Tiburon each spring.

Brandon Murphy – Rental Shop Manager

Brandon grew up playing soccer and has coached kids for Marin FC and several local schools, often spending part of the summer with his team in Europe. Brandon is an avid surfer and backcountry snowboarder and longtime Sugar Bowl season pass holder. Brandon can be seen or should we say can’t be seen snowboarding as he disappears into the backcountry each season. Brandon has surfed and snowboarded everywhere from South America to Alaska. Brandon uses his split board when touring to the Peter Grubb Hut off Donner Pass or Ostrander Hut in Yosemite and brings hands-on experience to our split board customers as well.

Lauren Helbig

Lauren grew up in Marin, graduated from Cornell University and is currently living in New York City. Lauren is responsible for Demo Sport’s Social Media and manages to keep us relevant from a distance. Lauren and her family are snow skiers, snowboarders, water skiers and wakeboarders. No wonder she is able to keep a finger on the pulse! Lauren checks in when home for holidays and the annual family Tahoe Ski Trip. Lauren’s “real job” takes her to Europe, Asia and coast to coast for weeks at a time although she still manages to report from abroad. Traveling gives her the opportunity to see how the rest of the world interacts with the out-of-doors.


Morgan Denker

Morgan is in her first year at Demo Sport. Morgan is a student at Terra Linda High School with a passion for skiing. Morgan gives us hope that the next generation will not all view the slopes from a video screen. Morgan spends much of her summertime outdoors as well as a local camp counselor. With excellent academics one can bet her collage of choice might not be too far from the slopes.
