My name is JR Giernger and I work for Penn Detroit Diesel Allison, we are a Distributor, service and parts provider for Detroit Diesel Engines, Allison Transmissions, and MTU. What I am trying to find out is who are some of the drilling companies and locations in Pennsylvania and Central & Western NY. I am trying to expand our business in our off road division and offer our services to the drilling contractors. Can anyone point me in the right direction? Thanks. JR
