Tetra Tech recognizes that tremendous entrepreneurial spirit and innovation exists in the small business community. We believe that by working with smaller companies—companies that share our non-bureaucratic and flexible approach—we can form competitive, high-performance teams.

The success of our mentor-protégé relationships have resulted in multiple awards recognizing our outstanding mentor-protégé teams. Our small business partners have developed, expanded, and even become mentors in their own right.
