Pacific Northwest Region

With more than 25 years of environmental consulting experience in the Pacific Northwest—first as Adolfson Associates and then as ESA Adolfson—we understand the unique challenges and opportunities facing our clients.

From developing infrastructure to meet a growing population to restoring a blighted shoreline in an area ripe with endangered species and natural resources, our team delivers effective solutions unique to the Pacific Northwest.

We service municipal, state, federal and private-sector clients throughout the Pacific Northwest including Alaska, Washington, Montana, Idaho, Wyoming, and Oregon.
