Primera Listed Among Top 500 Design Firms in the Country

Primera Engineers is proud to be listed in Engineering News-Record’s (ENR) Top 500 Design Firms and ENR-Midwest’s Top Design Firms for 2025. This marks our thirteenth and twelfth consecutive years on these lists, which rank U.S.-based design firms by design revenue from the previous year. We are ranked number 361 nationally and number 56 in the Midwest, covering Illinois, Indiana, Wisconsin, Missouri, Ohio, and Michigan.

Primera has continued to experience significant growth as reflected in our long-standing ENR rankings. We recently gained Female Business Enterprise (FBE) certification from the City of Atlanta and opened an office near Hartsfield-Jackson Atlanta International Airport, expanding our presence in the Southeastern U.S. Additionally in June 2024, we acquired Denver-based Corey Electrical Engineering and established a new office in Englewood, Colorado to support increased projects and team members. With the addition of these two new locations, our footprint now extends beyond Illinois, Indiana, Pennsylvania, and Texas.

“Being included on the ENR lists is a reflection of our firm’s growth and momentum,” says Erin Inman, President & CEO. “We’ve been intentional about expanding our reach and capabilities, and this recognition shows that our efforts are paying off.”
