Rock Creek Conservancy Welcomes Obama Era Senior White House Environmental Lawyer as Board Chairman


BETHESDA, MD, January 17, 2018 - Rock Creek Conservancy today announced the appointment of Gary S. Guzy as the Chairman of their Board of Directors for 2018.

Mr. Guzy is currently senior counsel at Covington & Burling LLP in Washington, D.C. where he is a member of the firm’s environmental, clean energy, public policy and government affairs practices. Previously, he served as the Deputy Director and General Counsel of the White House Council on Environmental Quality during the Obama Administration and was formerly General Counsel of the U.S. Environmental Protection Agency and Counselor to the EPA Administrator during the Clinton Administration. Mr.Guzy served on the Conservancy’s Board of Directors for a year prior to appointment.

“There can be no better sign of the Conservancy’s tremendous impact and growth over the last few years than the fact that someone of Gary’s stature in the environmental community has agreed to lead us over the next few years,” stated Scott Siff, who has been a member of the Conservancy’s Board of Directors since 2013 and who served as the Board Chairman from 2015 to 2017. He continued, “We are so excited to have him as our new Chair.”

Mr. Guzy’s appointment marks the growing influence of the Conservancy, which started as the living room project of 10 passionate local environmentalists and which has expanded exponentially in the past four years. The organization has grown from its bread-and-butter volunteer work (trash clean-ups and invasive plant removal) to become the driving force behind large restoration and local conservation efforts throughout the Rock Creek watershed in Washington D.C. and Montgomery County, Maryland.

Four prominent new Directors, who share the organization’s commitment to the local environment, have also been appointed to the board this year. These new members will play an integral role in extending the reach of the Conservancy to new audiences.
