Our People

We provide a supportive environment that fosters teamwork & upward mobility.

From an express lane widening, interchange reconstruction, bridge replacement, bicycle trail, park and ride, storm damage repair, to a park, a Mark Thomas project is a project defined by its seamless design, community focus, and thoughtfulness towards the surrounding environment. It’s not about simple connection, but creating a better way for all of us to Move Forward.
