Founded 1986
   
Brief History GL Communications was formed by Vijay Kulkarni and T. Bruce Yost on October 22, 1986. Vijay and Bruce met in 1985 while working as Engineers at FiberTrak in Reston, VA. FiberTrak was a company formed by two railroads ( Norfolk Southern & Southern Pacific) to design and build a communications network along their railroad right-of-ways across the United States. The project was "dropped", but a friendship and long-term partnership that has lasted twenty years was formed. Out of this friendship, GL Communications Inc. was born.
