Our Mission at TDM

TDM, Technical Design & Marketing Service, based in West Chester, PA, provides complete solutions for specific areas of the environmental market. That is, we do not offer every product for every industry but the applications we do address we do so completely, often offering multiple solutions for your application as well as all the products you require for that application. Though we are proud to sell some of the best products in the market, we look beyond the individual product and provide the best solution to your application, even if that means referring you to someone else.
