Dwight has been teaching geology and environmental science at WPC since 1994, which was soon after he moved to Portland to work for the U.S. Geological Survey. He worked as a hydrologist, studying and describing the water quality of streams, rivers, and aquifers. He retired from the USGS in 2012 and continues to teach part time at WPC, as well as volunteering as an educator at OMSI.

Dwight loves learning, science, and the mission and atmosphere of Warner Pacific College. He and his wife live just on the other side of Mt. Tabor. They enjoy traveling the west for hiking, and journeying to Japan to visit relatives.
