Spokane Office
Year Started: 1995

General Manager: Karl Kolb, S.E., LEED AP

The Spokane office was the result of a merger between Coffman Engineers and the structural firm Peden Petersen & Lee (PPL) in 1995. PPL was well ingrained in the community and Coffman has carried that spirit through since joining together. Employees are regularly found volunteering for causes and supporting civic endeavors. We are truly involved and engaged in Spokane and the surrounding region. The office thrives on being integrated on multiple levels ... not just technically in our work, but also as good friends spending time together after hours and fostering a culture of healthy and whole people. The culture is like that of a family working to help one another achieve their best, which naturally translates to success for our clients. Stop by anytime to see us as we'd love to show you around and answer your questions.

Hood River Satellite Office

Spokane’s Hood River Satellite Office is the result of a longtime Coffman employee – senior structural engineer Steve Hawk, S.E – relocating to Hood River, Oregon. The office was opened in 2010 to allow Steve the opportunity to simultaneously pursue his passions of engineering and windsurfing.  The location of the satellite office allows Coffman to provide clients in Hood River, Portland, Vancouver, and surrounding areas with the benefits of Steve’s local presence backed by the full capabilities and support of the Spokane office.

The Spokane office is nestled in the skyline of the city.
