Exponent opened its Seattle-area office in 1997 through the acquisition of PTI Environmental Services in Bellevue, just 10 miles east of downtown Seattle.   Though this office has drawn people from across the United States, many have Northwest roots in local educational institutions including University of Washington, Washington State University, Seattle University, University of Idaho, University of Montana, and Oregon State University. We serve both small and large companies, government agencies, insurers and their counsel in the Pacific Northwest and Alaska.
