The story
The company was founded by Brian Glassel and Tim Nicholson in 1997 on the east side of Madison, Wisconsin. Two years later Timothy Archer and Neil Spath opened a store on Madison's west side. Since then, two more stores have opened in the Madison area: Fitchburg and downtown Sun Prairie, as well as one in Oshkosh. GN Independents, the franchising arm of Glass Nickel Pizza Company, began franchising, with the first franchised store in Green Bay, Wisconsin and the second in Brookfield, Wisconsin. The Sun Prairie location was destroyed in a July 10, 2018 natural gas explosion in downtown Sun Prairie, and reopened in a new location on 815 W Main St in October 2018. On March 2, 2020, the company opened a store in Rib Mountain, Wisconsin/Wausau, Wisconsin. The new permanent Sun Prairie Wisconsin opened up in March 2022
