Together, everything is possible.

Nearly 40 years ago, Mortenson completed its first project in the Portland area. Since then, we have been building partnerships and projects across Oregon and Southwest Washington in a variety of markets including education, sports and performance venues, semiconductors, healthcare, hospitality and federal government.


Mortenson is a builder and developer focused on early engagement with our customers. By offering integrated services, we’re aiming to improve the design and build experience. We’re always looking ahead for solutions that allow our customers and our company to improve their business and make a greater impact in the community.

We're looking for talented professionals to join our Portland team!

With all the moving pieces in Healthcare, it is reassuring to know that our partners at Mortenson protect and share our same vision of the patient as the center of care. Their attention to detail, safety and the customer relationship is exceptional.
