Dennis Markatos-Soriano
Executive Director

Dennis Markatos-Soriano is an East Coaster based in the ECG community of Durham, North Carolina. Born and raised in the small town of Pittsboro, NC, Dennis attended the University of North Carolina at Chapel Hill. Upon graduation in 2001, he worked for NC Common Cause Education Fund before becoming the first executive director of the organization he had co-founded earlier, Students United for a Responsible Global Environment (SURGE). After three great years leading SURGE, he moved up the eastern seaboard to attend the master’s program in public affairs at the Woodrow Wilson School of Princeton University.

He came out of the program with fresh knowledge on how to help leaders throughout the US address climate change and energy security. In 2008-09, he was a featured writer through blogs and op-eds based in another nonprofit initiative he founded, Sustainable Energy Transition (SET) based in New York City. The opportunity to lead the completion of the East Coast Greenway was a perfect one to make a tangible climate impact while simultaneously addressing other issues he is passionate about–including lowering health care costs, lowering transportation costs, creating good jobs (constructing the trail), and driving a green economic recovery. When he is not working with ECGA staff, volunteers and allies to complete and promote the greenway, you may find Dennis playing basketball, riding his bike, and otherwise enjoying life with his wife, young sons, extended family, and friends.
