We believe in the dramatic importance of the Inland Waterways System. We have high regard for those companies, large and small, that work and grow along its banks: manufacturing, shipping, warehousing, and providing support and supplies for the good work done there. We understand the importance of the IWS in the larger context of American commercial responsibility, profitability, and success.

As the marketing arm of the Transmodal Performance Group of companies, our goal is to ensure exposure for those ideas and organizations that grow the IWS and our nation’s awareness of it. We offer promotional support to companies just like all those in our own corporate portfolio: barge terminals, harbor services, manufacturers, stevedoring operations, port authorities, transportation companies, grain and fuel co-ops and all their kin which help to make the IWS hum.

As far as success on the Inland Waterways System is concerned, we believe a rising tide lifts all barges. Effective marketing and public relations get your name in front of the customers and investors necessary to help you grow – the right way.

To see how we might engineer a more profitable impact for your business, please email Edward Robinson:, or phone him at 317-631-0234.
