As Tetra Tech has grown and changed throughout the past 50 years, our reputation for superior technical excellence in our projects has remained constant. Each employee embodies this legacy, which is manifested in every project we complete. The sum of this experience defines us. While each of our 400 offices around the world is unique, we share a common culture—our Tetra Tech DNA.

Our 50th Anniversary series features our people discussing how they define Tetra Tech’s DNA. From one of our founders to recent college graduates and from the corporate headquarters to the field, our people use similar words to define our DNA: entrepreneurial, collaboration, family, solutions, people, passion, science, and technology.
