GlenMartin a division of TWR Group is an ISO 9001:2008 certified international corporation specializing in infrastructure development and design. We were most recently purchased by the TWR Group on December 28th 2010.
In 1918, our great-grandfather, William Christopher Martin, founded W.C. Martin & Son Machine Shop and Welding near Boonville, Missouri. Originally, the company engineered, designed, and built machines and appliance parts for various industrial companies located in the Mid-West. However, in 1982, the company enlarged its production capabilities and dedicated its resources to the development of products for the communications industry. Rapid expansion required the company to incorporate in that same year.

Today, we still emphasize honest principles and well-engineered products at the best possible prices. Most importantly, we look at everything from the customers’ perspective. Only in this way will our customers have the confidence that their needs will be understood and met.

GlenMartin fully embraces, and aggressively invests in innovation. Our aspiration is to distinctively serve customers. A necessary condition to accomplish this is a steady stream of innovative products and services. We believe the continued improvement of current offerings and the strategic development of new ones is a key to our continued growth and success.
