Sellen is a builder. A builder of partnerships. A builder of community. A builder that seeks to add value to the organizations we work with and within the neighborhoods we live and work.

As the largest locally owned commercial construction firm in the Pacific Northwest and one of the first contractors to join the USGBC, Sellen has been at the forefront of the sustainable design and construction movement since the mid-1990s. We offer innovative and thoughtful solutions that are always economically viable and support our clients’ overarching sustainable objectives, creating goodwill within our local community.
Since our founding by John Sellen in 1944, Sellen has been guided by the philosophy that we can make a positive impact in the world by bringing success to our people, our partners and our clients. We’ve had the good fortune to work with a collection of world-class companies, organizations and public institutions that make the Pacific Northwest their home. From high-rises to hospitals, and historic renovations to high-tech facilities, Sellen has delivered some of the region’s most important projects. Our clients tell us that over the years we have become more than a trusted and innovative construction company – they consider Sellen a strategic partner and valuable member of their development team.
We’re proud of what we’ve accomplished together and, more importantly, we’re excited about the possibilities that lie ahead.
