Our telecommunications services company serves the Baltimore metropolitan area, as well as the Mid-Atlantic region, but is available to work anywhere in the nation. One of our better known projects is the massive installation project at the Sheppard Pratt Health System in Towson, Maryland.

Our work on this project was profiled in the leading trade publication Cabling Installation and Maintenance.
