In 1970, Sam Concelman Sr. and his cousin, Rick, leased a gas and service station from Pennzoil. At this time, the building had gas pumps in front of the building and only one car lift in the garage. Around 1979, Sam Sr and his partner moved to a larger building and Sam’s brother in law Ed Borgen took over the Glenshaw Pennzoil. In 1981, Sam Concelman Jr. was in high school. He began working at the garage pumping gas and working on cars.
In 1985, Ed bought the gas and service station from Pennzoil, when the corporation decided to get out of the gasoline business. As part of the transition, Pennzoil removed the gas pumps, and left the service station.
Meanwhile, during this time, both Sam Sr. and Sam Jr. worked at a local Toyota dealership as a Service Technician and Collision Technician, respectively.
In 1992, Sam Sr. and Sam Jr. become co-owners of Glenshaw Auto Service, purchasing it from Ed Borgen. In the two-bay garage, they provided both mechanical repairs and auto body work.
In 1995, they renovated the garage, adding a second car lift to the existing bay and expanding the building to add two more garage bays for auto body work.
