David Stitzhal
President

David (he/him) started his environmental career standing knee-deep in garbage when he designed and implemented what is arguably one of the nation’s first landfill sorts in the late 1980’s.

In 1993, after working for Cornell University’s Waste Management Institute, local governments, environmental non-profits and other consulting firms, David founded Full Circle Environmental, Inc. He has served as President and Lead Consultant since that time, as well as serving on a number of local and national boards of directors. David currently serves on the Boards of UPSTREAM and the National Stewardship Action Council.
David has created a vast network of relationships with an array of talented colleagues across the U.S. He excels at bringing people and organizations together to achieve program and policy goals. Specifically, David has helped lay the groundwork for conservation programs setting the trend for the nation, including pharmaceutical take-back, electronics product stewardship and commercial sector recycling assistance. Recently, David earned the Understanding the Living Building Certificate through the International Living Future Institute.
David is known for a creative and results-oriented approach that has led to a number of award-winning projects. He has a BA from Swarthmore College in both psychology and sociology/anthropology. He has a Masters degree in City & Regional Planning from Cornell University.
