Firm overview

Saving Energy Is What We Do

Through careful long-term planning and life-cycle analysis, we advise clients on strategic investments that pay big dividends. Each year our designs save clients more 51 million kWh, meaning that in our history, we’ve kept more than half a billion pounds of greenhouse gas emissions out of the atmosphere.

Local Everywhere, International Resources

When you work with Salas O’Brien, you get the best of both worlds. Your project success will be driven by our international pool of experts, yet you’ll get the attentive service and focus on detail that you’d expect from a small, local firm.

Employee-Owned Means We Care

Being employee-owned means that every Salas O’Brien team member cares for each other and for the success of our clients. With a team retention rate consistently above 90%, we invest in our team as owners, and they provide clients with unmatched project continuity and consistency.

How We Create Success

With each collaboration, our relationship with you grows. We expand our knowledge, maximize our efficiency, and get stronger, project after project and year after year. That’s the power of long-term relationships.

Step 1: Listen & Collaborate

We begin by listening and collaborating to determine the best path forward.

Step 2: Understand & Define

We work to understand your needs and determine the steps, standards, and processes needed to meet them.

Step 3: Execute & Deliver

Using an integrated approach that emphasizes technical performance, project management, quality management, and safety, we execute and deliver.

Step 4: Learn & Leverage
