David left the Bronx, NY for San Francisco back in the 1970s with a Masters Degree in Environmental Engineering and a desire to put his career and life experiences to their best use.  He has since worked throughout the West as a consultant and inspector for various private organizations as well as federal, state, and municipal agencies in the fields of water and air quality as well as with hazardous waste issues.  He was eventually invited to create an Environmental Engineering program at Portland Community College where he worked for 23 years before retiring.

During his tenure at PCC, David travelled to Africa (Kenya, Tanzania, Mali), Mexico, as well as statewide to promote renewable and solar energy projects. 

Since his retirement, David has dedicated his time to local environmental and water quality issues.  You can find him cleaning and sampling our nearby rivers and lakes, maintaining hiking trails, tutoring high school students, and promoting a major global transition from fossil fuels to a renewable energy system. He is a dedicated volunteer of the Columbia Gorge Ecology Institute (now GEO — Gorge Ecology Outdoors,) Friends of Trees, Columbia Riverkeeper, Solar Energy International, the Oregon Conservancy Foundation, and, of course, Friends of the White Salmon River. 

David resides in Lyle, Washington with his wife Julie and spends as much time as he can with his grandchildren.
