Salas O’Brien’s first merger announcement of 2023 creates a team of over 1,750 across North America

Salas O’Brien announced today that Dufoe Consulting Engineers has joined the company, creating a stronger combined team of mechanical engineers and sustainability designers. This expands Salas O’Brien’s presence to more than 60 North American offices with over 1,750 team members and 380 registered professionals. Dufoe will combine forces with the nearly 150 Salas O’Brien team members currently based in Phoenix, Arizona and Southern California.  

Dufoe’s capabilities and portfolio complement Salas O’Brien’s mechanical engineering and sustainable design team, increasing our unique ability to provide comprehensive, multi-disciplinary services such as energy analysis, HVAC and plumbing design, fire protection, and LEED design services. 

As the next step in Salas O’Brien’s strategy to be local everywhere, with international resources, the Dufoe team will continue to be managed by its current leaders and will adopt the Salas O’Brien name after a transition period. 

The merger closed on December 31, marking the eighth company to join Salas O’Brien in 2022.  

“We are excited to welcome the talented team from Dufoe Consulting Engineers,” said Darin Anderson, Salas O’Brien chairman and CEO. “Their skills and expertise will elevate our project delivery even more, bringing greater impact for the clients and communities we serve.”  

Salas O’Brien continues to grow as part of an ambitious plan to create the most respected engineering firm in the world, as measured by clients and team members.  

“We are excited for our clients to be introduced to Salas O’Brien’s broader spectrum of in-house services,” said Jeff Dufoe, president of Dufoe Consulting Engineers. “Uniting with Salas O’Brien will create a future with even more opportunities for everyone.”
