JEM GPR began operations in 2019 and was founded by four veterans of the concrete cutting industry. The ownership group is made up of three siblings: Eddie Anthony, Amanda Ridenour, and Tyler Anthony, along with Joshua Ridenour as the Executive Manager. JEM GPR truly is a family business, and concrete work runs in their blood. Combined, they have 30+ years of experience at JEM Concrete Drilling & Sawing, Inc. Together, they recognized the need for a locally owned and operated Ground Penetrating Radar and locating service in northern Indiana.
