Primera Ranks #11 on Crain’s Chicago Business’ 2025 List of Largest Engineering Firms in Chicago

July 16, 2025

Crain’s Chicago Business recently released its 2025 list of the largest engineering and architecture firms in the Chicago area, and we’re excited to share that Primera has come in at #11 on the engineering list! The rankings are based on the number of locally licensed engineers and includes 24 other firms with offices across the greater Chicago region. We’re grateful for this recognition and proud to be moving up the list alongside some of the most respected firms in our region and industry.

This year’s jump reflects a lot of hard work, growth, and momentum across the firm. From our expansion to Atlanta to moving into larger office spaces in Chadds Ford, PA and Denver, CO, to continuing to invest in our people, Primera has had a big year. We were also honored to be named a Top Workplace for the fourth year in a row and recognized on several national and regional lists, including ENR Top Design Firms list for 2025.

“Our team continues to raise the bar,” says Erin Inman, President & CEO. “This ranking is a reflection of the talent, passion, and purpose that drives everything we do. We’re proud to be building a firm that’s not only growing but doing it with heart,” she continues.

We’re grateful to our amazing team and clients who make this kind of recognition possible. And while we’re celebrating this milestone, we’re also looking ahead and proud to be focused on continuing to develop the next generation of engineers and architects by giving back through the Primera Foundation.
