Duluth office overview

Coffman’s Duluth office is in a vibrant city at the head of Lake Superior, a hub of activity for the Midwest.

Led by Minnesotan Andrew Onken, NACE, our Duluth team offers specialized corrosion control and AC interference services. We have a long history of experience working with oil and gas clients in the Twin Ports and across the US. The Duluth office is focused on deepening our connection with existing clients and building new relationships in the region. The office also offers civil, structural, mechanical, electrical, and fire protection engineering services supported by regional offices.

Our local employees take great pride in their community, and you will find them spending time being active and engaged partners, fostering a positive culture and strengthening relationships. With world-class access to a variety of outdoor activities, the Duluth team frequents area trails, lakes, and cliffs, enjoying hiking, fishing, hunting, skiing, climbing, or simply enjoying a local craft brew near the beauty of Lake Superior.

The next time you’re in Duluth, stop by to say hi and learn more about the projects we’re working on. We look forward to connecting!
