We want to acknowledge here the passing of Mike Conway, in the fall of 2019. He is sorely missed. Mike worked for us since 2007, and had over 40 years of experience working in project management and design for us and other engineering firms. Although not a licensed engineer, he was a force of nature and problem solver. For 16 years, Mike served as the City of Washougal’s Public Works Director. In this position he ensured that infrastructure was in place for the future, during one of the largest growth spurts in the City’s history.
We are proud to have worked with Mike Conway.

In Remembrance

Mike Conway
