Regional Director

“I’ve always been interested in politics and the environment,” Laura Cohen recalls. “In fact, I ran for office in high school and became our school’s first Commissioner of the Environment.” She followed these passions through her studies, completing a political science degree at the University of California, Santa Barbara, and a law degree from the University of California, Berkeley.

After several years as an entertainment attorney for MGM/UA (which, like public policy, is a highly collaborative environment with lots of passion and egos), she shifted her focus to public interest work, becoming deputy chief of staff to a California State Senator. Laura joined RTC as California policy director, drawing on her legislative experience, and established RTC as a prominent player in statewide transportation and recreation policy.

Since being promoted to Western Regional Director, with responsibility for RTC’s program work in six western states including the Bay Area Trails Collaborative, Laura has been instrumental in increasing funding for bicycling, walking and trails by more than $200 million over the past decade. She played a key role in shaping the legislation that created California’s new Active Transportation Program and in preserving the state’s Recreational Trails Program. Laura is also a frequent speaker on active transportation policy and funding issues and has co-authored numerous RTC reports, including the 2009 California Rails-with-Trails Survey.

In her spare time, Laura and her family enjoy hiking in the San Francisco Bay Area, whitewater rafting and adventure traveling. Past excursions include safaris in Africa and leading volunteer teams for Habitat for Humanity International in Romania, New Zealand and Botswana, to name a few.
