Stephen Aiguier

Founder + President
  • Stephen Aiguier

A wealth of knowledge, passion and expertise, Stephen leads the Green Hammer team in designing and building structures for life.

A pioneer of Oregon’s green building movement, Stephen Aiguier founded Green Hammer in 2002, evolving the business into a full service design-build firm committed to advancing the highest standards for sustainable homes and green buildings.

In the first few years of operation, Stephen led Green Hammer in building five of the nation’s highest-scoring LEED-Platinum homes. An early Certified Passive House Consultant (CPHC) and building-science expert, Stephen speaks frequently at green building conferences and teaches Earth Advantage Institute’s Sustainable Homes Professional class in Portland.

A stern advocate for the protection of wilderness areas and restoration of natural forests, Stephen has supported countless non-profits and campaigns to both protect wild places and responsibly steward our natural resources. In 2004 Stephen co-founded Urban Timberworks, which transforms urban salvaged trees from the Portland metro area into artisan furniture. (The company is now owned by former employee, Leland Gilmore.) In 2005, Stephen co-founded the Build Local Alliance as a forum for connecting local FSC-certified forest stewards to builders and architects in the Portland region. Currently Stephen sits on the board of the environmental education non-profit Opal Creek Ancient Forest Center.

Stephen Aiguier has been passionate since the inception of Green Hammer about a triple bottom line focus and a staunch advocate for people in the people, planet, and profit equation. In 2017 Stephen successfully led Green Hammer’s effort to become a Certified B Corporation, joining more than 2,000 companies in 50 countries with one unifying goal—to use the power of business to help address some of the world’s biggest social and environmental challenges.

In 2011, Stephen was named one of Portland Business Journal’s “40 Under 40”, and as one of Sustainable Business Oregon’s Top 10 Sustainable Built Environment Leaders to Watch in 2012.

An active cyclist, surfer and outdoor enthusiast Stephen also enjoys exploring the Pacific Northwest with his wife Karen and daughter Olive.
