About Our Spokane Engineering Firm

Year Started: 1995

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

The Spokane engineering firm 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.
