In Memory of Trails and Environmental Justice Advocate Guy O. Williams
Rails to Trails Conservancy was deeply saddened to learn of the loss of our dear friend and colleague, Guy O. Williams, who passed away on July 29, 2025. A nationally respected leader in the environmental justice and trails and active transportation movements, Williams—who served as an RTC board member from 2002 to 2021 and board chair from 2013 to 2016—tirelessly endeavored, both in work and in life, to make communities better places to live and the outdoors accessible for all. He will be greatly missed.
“Whatever his role at any given time, he always approached the work with passion, purpose, generosity and empathy.”
—Kevin Mills, Vice President of Policy, RTC
“Guy was one of those very special people who touched the lives of many,” affirmed Ryan Chao, president of RTC. “We’re so grateful for his long service on the Rails to Trails Conservancy board, and his legacy lives on in all the communities that are healthier from his life’s work.”
He continued, “Our hearts go out to his family and very large community of friends that mourn his loss.”
Williams grew up in Maryland and received a Bachelor of Science from Bucknell University. Throughout his career, he applied his knowledge of social equity and environmental justice to a number of leading organizations in the field, including the Environmental Defense Fund, the National Wildlife Federation, Detroiters Working for Environmental Justice, which he co-founded, and his firm, G.O. Williams & Associates.
RTC remembers Williams for his impactful ideas, his strong sense of purpose, and his drive to turn thought leadership into action and positive outcomes.
“Guy brought a very valuable perspective to our board,” said Keith Laughlin, who served as president of RTC from 2001 to 2019, and worked closely with Guy. “As the executive director of Detroiters Working for Environmental Justice, he understood how trails can improve the health of urban communities and the people who live there.”
“He pushed me and the board to make sure everything we did—our financial management, our programming and how we talked about RTC—was done with authenticity and reflected the deep desire for fairness and justice [we have] in our efforts to increase access to trails and active transportation,” affirmed Kate Kraft, former executive director of America Walks, who joined RTC’s board shortly after Williams.
Kevin Mills, RTC’s vice president of policy, knew Williams since their days of working together at the Environmental Defense Fund in the early 1990s. Mills remembers Williams’ deep understanding of RTC’s trail advocacy work and its strategic intersections with his environmental justice work in Detroit. “He would pick up on RTC’s latest objectives—such as innovative ways to fund trails or assess trail connectivity—and identify opportunities to advance them, sharing his network of contacts and pounding the pavement to secure support,” said Mills.
He continued, “He was also a force to be reckoned with in the board room. He would listen carefully to everyone’s opinions and then weigh in with a thoughtful position that blended respect for his peers with a challenge for RTC to strive to be as impactful as possible, because he believed—and led others to believe—that it was essential for the good of the world that we be our best selves.”
Williams’ colleagues note that while he was chair, he led the RTC board and its business strategies with a strong sense of integrity, and championed impactful communications and marketing initiatives that helped raise RTC’s visibility. His thought leadership is attributed as being pivotal to the launch of RTC’s TrailNation™ initiative, which aims to accelerate trail network development nationwide, and today contains a portfolio of nine local and regional trail network projects spanning more than 10,000 miles.
He legacy lives on through the local and national organizations he helped shape and mold, and the friends and colleagues he touched along the way—who remember his indelible mark on the trails and environmental movements, and the endless kindness and support he emanated on a daily basis.
“[He] was good at building consensus, and always had a smile on his face,” said Laughlin.
“Whatever his role at any given time, he always approached the work with passion, purpose, generosity and empathy,” Mills stated.
“Guy left his mark on many people, and RTC is really lucky that he was part of making us who we are today,” said Kraft.
In lieu of flowers, Williams’ family suggests that donations be made to the Charles R. “Pop” and Virginia H. Williams Endowment Fund, an environmental justice organization of your choice, or a local AA chapter in honor of Williams’ quiet but powerful commitment to recovery and second chances.
