Since day one, the Portland region has been our headquarters. The city’s culture of innovation, environmental sensitivity, and collaborative spirit mirrors our own. As longtime leaders in sustainability, we participated in some of the early west coast LEED projects as well as one of the first certified net zero energy schools. Backed by 45+ years of consulting practice, we continue to be known for our fresh approach, creative design, and resource sensitivity.
