Haag and Salas O’Brien Announce Partnership

Strength in Unity: Haag & Salas O’Brien Announce Partnership

We are proud to share that Haag has merged with Salas O’Brien, an employee-owned engineering and technology firm at the forefront of sustainable design. We are joining an organization with more than 85 global offices and over 3,550 team members.

We are confident this merger will positively impact all our clients. Our capabilities and portfolio complement Salas O’Brien’s existing work while increasing our combined team’s ability to provide comprehensive, integrated, multi-discipline engineering and consulting services.

Here are some key facts:

  • The entire Haag leadership group and team are very enthusiastic about this partnership. You will continue to work with the same team of experts and experience the same decision-making, quality of work, and service delivery. As integration occurs, Haag’s service offerings and geographic coverage will expand.
  • The local Haag leadership team will remain intact with autonomy to best serve our clients. 
  • We share a vision, culture, and leadership style with Salas O’Brien. This was a key factor in our decision to merge with them. We also share a strong portfolio of complementary work.
  • We can now offer additional in-house expertise and design services like sustainability/green energy, industrial process, pharmaceutical and healthcare, data centers, food and beverage, fire suppression, lighting and acoustic design, but only when it makes sense for you, other team members, and the project.
  • We will have greater depth of support for many of our internal and overhead operations, thus improving our ability to serve you and your assignments. This merger also broadens our in-house expertise for key services like mechanical, electrical, and structural design.
  • Haag’s email and website will continue to be maintained and will transition to Salas O’Brien when practical.
  • Our name is now “Haag, a Salas O’Brien Company.” When Haag leadership believes the transition is complete and when the timing is right, we will adopt the Salas O’Brien name.

We’re very excited about this announcement and look forward to continuing our partnership with you. If you have any questions, don’t hesitate to reach out. Learn more.
