"Concord Engineering has been an outstanding and supportive teaming partner on our transit projects and traffic engineering studies.  As evidenced by our success in delivering quality work to our clients, Concord has been instrumental in streamlining our projects by augmenting our staff or leading tasks independently.  We fully endorse Concord for any transportation project involving traffic engineering, ITS or transit planning elements."

Project Manager Seattle Private Contractor

"Concord Engineering helped us develop a viable solution for a congested major traffic project with a lot of initial resistance in the local community. They were able to work with all the stakeholders, including the local community and government leaders, to find a solution that met everyone's needs. We were so grateful to have them on our team throughout this process. Our final project came in right on schedule and under budget and each Concord team member we worked with was capable, professional, and a pleasure to work with!"
