TWM, Inc., one of the top 10 largest engineering and geospatial firms in the greater St. Louis area, announced it recently opened a new branch office in Chattanooga, TN. In the fall of 2021, TWM acquired Meyer Transportation Consultants to expand its transportation and traffic engineering services throughout middle and eastern Tennessee. Hiring additional staff to service current and future clients in this rapidly growing region prompted the need for another designated office space.

Plans to expand TWM’s services within Tennessee reflect the company’s growth strategy in pursuing new opportunities. “We’re confident this new office will enhance TWM’s core service capabilities and operations network. Having dedicated staff available at local levels will optimize our business operations, support our professional growth, and result in a higher level of client engagement,” said Robert DeConcini, President.

New location expands company’s presence in Tennessee region

The new Chattanooga location, at 1208 Point Centre Drive, Suite 250, is an organic evolution that reflects the firm’s ongoing commitment to have another geographical physical presence within the region and establish closer ties to local clients and communities. “TWM is excited to expand into Chattanooga and grow our capabilities throughout the state of Tennessee,” said Stephen Meyer, PE, Chattanooga Branch Manager and Chief Traffic Engineer. “We are determined to continue our efforts in serving the Tennessee market with innovative technologies as well as our personalized service to each client.”

In addition to the branch office locations in Franklin, TN and Chattanooga, TN, TWM has seven office locations in the Illinois and Missouri bi-state region. In Illinois, the corporate headquarters is based in Swansea, with additional offices in Edwardsville, Waterloo, and Peoria. In Missouri, there are offices in downtown St. Louis, St. Charles, and Columbia.
