- Carpenter Marty Transportation was founded by Kevin Carpenter and Bill Marty. The company, previously known as WD Partners, began servicing governmental agencies in 1998. In December 2008, Kevin and Bill were appointed Directors of WD Partners' Public Works Department and initiated a rebranding as WD Transportation. Recognizing that infrastructure design was not WD Partners' core business, Kevin and Bill acquired ownership of the division in late 2012. CM retained all employees and ODOT prequalifications, and we continue to provide the same quality design services to our clients and project partners as we did under the WD Transportation name.
