Kevin and Bill started working together in 2000 and swiftly rose to become Directors of the Public Works Division at their company. Realizing that infrastructure design wasn’t their employer’s main focus, they took ownership of the division and launched Carpenter Marty Transportation in January 2013.

At Carpenter Marty Transportation, we’re proud to boast a team of over 50 employees spread across four vibrant locations: Cincinnati, Ohio; Columbus, Ohio; Charleston, West Virginia; and Nashville, Tennessee. With a diverse array of talents and expertise, our dedicated staff collaborates seamlessly to deliver exceptional results. From designing to planning to surveying, we offer a comprehensive suite of services tailored to meet our clients’ needs.


More than just a firm, we’re a team united by a shared passion for what we do. We believe that every project we undertake, big or small, holds significant meaning. This philosophy drives us to consistently exceed expectations, relentlessly innovate, and make a positive impact in the communities we serve.
