We are thrilled to announce that Salas O’Brien has once again ranked among top companies in notable industry reports, climbing the rankings to place #11 on Consulting-Specifying Engineer’s 2023 MEP Giants and #8 on Building Design + Construction’s Giants 400—2023 Top Engineering and Architecture Firms. We are also celebrating our 11^th year in a row on the Inc. 5000 list.

Our consistent presence on each of these lists is a significant achievement and is a direct reflection of our team’s unwavering commitment to delivering the highest quality solutions for our clients and partners.

MEP Giants and Giants 400 reports are both highly respected in the AEC industry. MEP Giants features the top mechanical, electrical, plumbing, and fire protection engineering firms in North America and Giants 400 ranks the largest architecture, engineering, and construction firms in the U.S. In each, Salas O’Brien’s 2023 placement surpassed our previous highest rankings.

This year also marks our 11^th year on the Inc. 5000 list, a rare accomplishment and exciting reminder of the trailblazing companies and passionate people pushing boundaries, innovating, and shaping progress across the globe.

These recognitions are in addition to others received earlier in 2023. At the start of the year, we jumped 24 spots to place #54 on Engineering News-Record’s 2023 Top 500 Design Firms list. We also ranked #3 on the 2023 Zweig Group Hot Firm List, which recognizes the 100 fastest-growing AEC firms in the U.S. and Canada. Each list ranks companies based on a different, data-driven measure of success.

We extend our congratulations and gratitude to our team members, clients, and partners who have all played crucial roles in our success.
