[1][2] Founded in 1989 as a software company, Full Service Network entered the telecommunications landscape in the early 1990s.
Throughout that decade, as land line phone services became competitive, FSN focused mostly on serving the commercial market of small to mid-size businesses.
Currently employing roughly eighty-five staff, the company is based at the US Steel Tower in downtown Pittsburgh.
In 2013, the Pittsburgh Business Times also awarded FSN with a "Best Places to Work in Western Pennsylvania" honor.
