Bill has more than 45 years of experience in all phases of geotechnical consulting: geologic reconnaissance, field exploration planning, drilling operations and logging, feasibility studies, design, construction monitoring, and construction management.  His years of experience in the Pacific Northwest have made him a leading expert on local geology and soil conditions.  

Bill's specialties include interpretation of glacial stratigraphy for design of civil works projects, slope stability evaluations in a multitude of geologic conditions, timberland mass wasting in mountainous terrain, and the geotechnical aspects of hydroelectric facilities, including small and large diameter pipelines.  An expert in the identification and geologic interpretation of landslides, Bill was the principal investigator for a study that involved more than 1,400 landslides for the City of Seattle.
