In 1984, Laramie, Wyoming became home to Trihydro, an engineering and environmental consulting firm started by a geologist and a chemist with a vision and a passion for developing sustainable solutions. In the early years, Trihydro was known and named for its technical expertise in geology, chemistry, and engineering. Since that time, we have advanced purposefully in environmental science, engineering, technology, and regulatory compliance to help our clients achieve their business objectives.

Today, we have more employees and more offices, and we continue to push ourselves to provide effective, responsive, and safe solutions across the globe. Our company culture is one of integrity, honesty, fairness, and trust and these values have made us one of the nation’s top engineering and environmental firms. As we continue to grow, we won’t lose sight of doing business our way—the way our employees, partners, and clients deserve.





As a growing company, we are dedicated to upholding a company culture that reflects core principles of integrity, honesty, and respect. The quality of our work, the value of our brand, and the dedication of our employees are carried into every project we take on.

We have found that our code of ethics is best described by the book Cowboy Ethics, What Wall Street Can Learn from the Code of the West. The core message of the Code of the West closely matches the way we operate our business and is reflected in our corporate culture.


Live Each Day With Courage
Take Pride In Your Work
Always Finish What You Start
Do What Has To Be Done
Be Tough, But Fair
When You Make A Promise, Keep It

Ride For The Brand
Talk Less And Say More
Remember That Some Things Aren’t For Sale
Know Where To Draw The Line
Leave It Better Than You Found It*

KEVIN T. "The work-life balance at Trihydro is great. Everyone is very understanding of your personal needs. For project work, I appreciate that there is an effort to pull in people from other offices to provide their insight or expertise to deliver solutions to our clients. Even with a nationwide team, no one is isolated to their specific office and the team works as one toward goals."
