Keith Laughlin became president of RTC in February of 2001, and since that time, has guided the organization’s efforts to become a national leader in the trails and greenways movement. Keith is responsible for overseeing all aspects of RTC’s trail development, policy advocacy and public education work, and regularly speaks before Congress and in the national media to establish strong support for trail networks and active-transportation infrastructure.

After 14 years as a senior staff person in the U.S. House of Representatives, he joined the executive branch, serving for eight years as Associate Director for Sustainable Development of the White House Council on Environmental Quality.

Laughlin's move into the nonprofit sector reflects his strongly held belief that a nationwide network of interconnecting trails can provide countless community benefits, including alternative commuting options and low- and no-cost recreational opportunities for people of all ages and abilities across the country.

Amy Kapp
Content Strategy Manager and Editor-in-Chief, Rails to Trails

Amy’s love for the outdoors stems from her childhood in western Pennsylvania, where she and her brothers often built tree-branch forts and hiked in the 24 acres of woods that made up her parents’ backyard.

She initially set her sights on the performing arts for a career, but realized in her early 20s that she and the industry were better off as friends. Eventually, she found her way to a small technology nonprofit in Pittsburgh, where she helped create and promote an online green map for southwest Pennsylvania. She went on to serve as a communications strategist for a number of outdoor and education-based nonprofits and as a writer for multiple publications, including Parks & Recreation magazine. In 2014, she joined RTC as content strategy manager, as well as editor-in-chief of Rails to Trails magazine and the TrailBlog.

When searching for new job opportunities, Donald’s wife (then- fiancé) Jessica mentioned that she missed being able to walk her dog on the trail near their old apartment. The impact the trail had on their lives and the local community resonated. A few days later, he saw the RTC job opening and decided to apply!

Jorge Brito
Trailblazer Society Manager

It was access to the W&OD Trail in Virginia—which Jorge rode frequently while growing up—that led to his lifelong love of cycling and eventual career in active transportation advocacy. “That trail connected me to the towns along its path and was a place of fun and recreation for me from childhood till now,” says Jorge.

Prior career credits—before joining RTC in 2016—include managing community outreach for the launch of Philadelphia’s bike share system, Indego, and serving as a development and event-planning staffer for the Bicycle Coalition of Greater Philadelphia.

Katie Guerin
Head of Strategic Initiatives

A defining moment for RTC's Katie Guerin: being assigned to ride the bus for a journalism class project while studying at the University of South Carolina (USC). It was a mode of transportation, she says, that was "so foreign to me, I might as well have been told to jump in a clown car and head for the circus." A native of Columbia, South Carolina, a town dependent on driving, the experience was an eye-opening one.

Since moving to Washington, D.C., in 2008, she has formed a great appreciation not only for public transportation, but for the impact that trails can have on their communities and the health of their inhabitants. Katie is proud to say that now, "even little old Columbia has jumped on the rail-trail bandwagon."

An avid Gamecock fan and runner, Katie got her feet wet and D.C.-ready as a press secretary on Capitol Hill. She comes to RTC from a consulting firm where she fundraised for a variety of organizations ranging from a land conservation trust to a sailing hall of fame.

"It’s exciting that I can help communities like Columbia have the opportunity to ditch those car keys and hit the trail!" exclaims Katie.

Despite this, Leeann has been an avid environmentalist and outdoor lover since her youth. She studied environmental science in college and recently received her Master of Public Administration from Columbia University, specializing in Environmental Science and Policy.

Before joining RTC, she completed a stint with AmeriCorps as a New Jersey Watershed Ambassador, getting her feet wet (sometimes literally) assessing river health and conducting environmental outreach at schools and in local communities.

Tom Sexton
Regional Director

If Pennsylvania had its own Environmental Hall of Fame, Tom Sexton would surely be in it. His résumé of conservation and alternative-transportation initiatives reads like an awards introduction, and RTC is very pleased to have Tom heading up our Northeast Regional Office in Camp Hill, Pa.

Having studied the environment, planning and geography in college, Tom's early career included working as a recreation planner for the National Park Service, and as a naturalist in New York City. His passion for preservation soon led him toward the political arena, in which he served as a congressional staffer for the 1st District of Maryland. He then established the Pennsylvania office of the Chesapeake Bay Foundation and served as executive director.

Tom joined RTC in 1991, the same year he founded the Environmental Fund for Pennsylvania. In the early 90s, he was the lead advocate for Transportation Enhancements (TE) to be allocated to local projects, and he led the effort to protect unused rail bridges and tunnels, which resulted in an 18-month demolition moratorium by the Pennsylvania Public Utility Commission.

Since then, Tom has been instrumental in leading RTC's policy, promotion and trail-assistance efforts across 10 states in the Northeast.

Tom is the author of several regional guidebooks, and he served as co-chair of the 1997 Pennsylvania Governor's Conference on Greenways and Trails. He was also co-chair of the 1999 International Trails and Greenways Conference in Pittsburgh.

Tom founded and now directs RTC's annual Rail-Trail Sojourn series, a trail-building program that, since 2002, has led thousands of bicyclists on rides throughout the eastern U.S.

Western Regional Office

Laura Cohen
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, 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.

Barry Bergman
Trail Development Manager

Growing up, the vacations of choice in Barry Bergman’s family always seemed to revolve around travel, camping and hiking, so it’s hardly a surprise he ended up working at RTC. But Barry has a special place in his heart for rail-trails.

“While in graduate school in western Massachusetts, biking was a great way to get to class, except for the harrowing roadway crossing over the Connecticut River,” he says. “Once the abandoned railroad bridge was rehabbed for the Norwottuck Rail Trail, it was something I appreciated every day.”

Prior to joining RTC, Barry spent 17 years as a public sector transportation planner, focusing on helping to create more balanced, less auto-centric transportation systems. His work included leading the Baltimore region’s first-ever bicycle, pedestrian and greenways plan as well as some more on-the-ground experience in Alameda, Calif., where he updated the city’s bike plan and partnered closely with the local transit provider.

As manager of trail development in RTC’s Western Regional Office, he has tried to visit as many trails across the region as possible, and on weekends, Barry can often be found taking in the natural wonders of the San Francisco Bay Area hiking trails.

He adds, “What can I say? I guess my name means ‘mountain man’ for a reason.”
