Built on doing things the right way.

In 1984, Laramie, Wyoming, became home to Trihydro, an engineering and environmental consulting firm started by a geologist and a chemist with a vision for doing things the right way. Founded on a commitment to employees and clients, we have advanced purposefully in environmental science, engineering, technology, and regulatory compliance.

Today, we have more people and offices and continue pushing ourselves to provide effective, responsive, and safe solutions. Our company culture is one of integrity, honesty, fairness, and trust. These values have made us one of the nation’s top engineering and environmental firms. As we continue to grow, one thing remains the same: our commitment to doing business the right way for our clients, communities, and people.
