Consulting Engineers

Leadership

If you're looking for a consulting engineering firm that provides quality designs and personal service, you've come to the right place. We over 170 engineers, designers, drafters and support personnel among our four regional offices in Portland, Oregon; Seattle, Washington; and Sacramento and San Francisco, California. You'll find our offices to be casual, friendly environments, full of people who truly enjoy their work. We emphasize the importance of teamwork and use multi-discipline production teams to provide our clients with the most efficient service possible. Even outside the office, we are an active and involved group of people, throwing ourselves whole-heartedly into events and activities and lending a hand in our communities.

Interface maintains a diverse project portfolio because we believe that a wide range of experience results in more creative solutions to our clients' needs. We've completed projects in more than 40 states and several international locations and have experience in commercial, educational, residential, industrial, hospitality, recreational and institutional facilities.

Throughout our firm's history, we've worked to provide our customers with a level of comfort, service and trust that exceeds their expectations. Our goal is to build long-term business relationships, providing high quality, individualized service that helps our clients succeed. We know that when it comes down to it, our business is more than just projects – it’s people. And we aim to reflect that philosophy in everything we do.
