About Us

Engineering with a purpose.

Integrity, sustainability, collaboration, and innovation. For over 45 years, we’ve built our consultancy around these values. These attributes stem from our primary goal: meet client needs, do more with less, and reduce our impact on the environment.

We thrive on challenging designs, and have developed a culture focused on providing staff the right tools to do their best work. We promote from within, offer mentorship and continuing education, and utilize the most advanced technologies – guiding practices that allow us to create optimal environments for our teams as well as our projects.

A half century of innovation.

Since our founding in 1969, Interface Engineering has earned a reputation for technical problem solving and engineering innovation. And we will continue to lead the way as an advocate for smart, efficient and sustainable solutions for future generations to come.
