LET'S REDEFINE POSSIBLE®

Doing what's best for your project

Mortenson’s Seattle office has been building complex projects in the Pacific Northwest for 40 years. We bring value to our customers by providing innovative solutions and treating every relationship –customers, design partners, and team members – as a partnership. Our commitment to relationship-based projects and alternative delivery allows us to optimize the best value for our customers.

The culture of Mortenson and what they bring to the worksite is so positive and impressive. Mortenson and the support that they have brought to this community has been amazing. There were a lot of hours put towards education and supporting businesses to take them through not only the process but to help them understand the certification and how they could elevate their business and their opportunities.
