Decisions for a sustainable planet
Since 1979, we’ve worked with public and private clients to ensure that students, communities, stakeholders, and governments can make inclusive and informed decisions about the natural and built environments.
Our Vision
Triangle was one of the first firms in the nation to offer environmental collaboration and conflict resolution. For over 45 years, Triangle has provided mediation and facilitation on some of the largest built and natural environment decisions of the Pacific Northwest.
Today, we provide neutral third-party facilitation and mediation support for decisions that involve hundreds of thousands of people across the western United States each year, and environmental education programs for tens of thousands of school-age children and hundreds of schools.
