In 1952, Glenn O. Hawbaker and his wife, Thelma, founded a small excavation company with the goal to build, serve, and advance local communities. First contracting with local State College builders, the company grew and expanded, officially becoming incorporated in the Commonwealth of Pennsylvania in 1965.

Currently operating 19 quarries and 7 asphalt production facilities across Pennsylvania, and southern New York, Glenn O. Hawbaker, Inc. continues to serve customers with an array of services including asphalt paving, road construction, gas well service, and construction, as well as engineering design services.
