Pat Dolan, Sr., a coal-handling superintendent for a large power plant, founded Conveyor Services Corporation in 1980. Pat and a small crew of craftsmen began servicing mines and power generation facilities in western Pennsylvania, providing on-site belt vulcanizing and belt repair.

Using an old World War II military ambulance to haul materials and equipment, Conveyor Services began its tradition of emergency response and quickly became known as "The Belt Doctors", on call 24 hours a day, 365 days a year.

Over the years, the organization expanded its capabilities and its size and has become the largest conveyor service organization in the United States.
