For over 70 years Krapf's has provided quality transportation services for most of Chester County's school districts and we rapidly expanded into Charter, Public Transit, and Para-transit. With over 1000 school buses in our fleet, we are one of the largest providers in the Commonwealth of Pennsylvania. In addition, we are certified by not only the U.S. Department of Transportation, but also by the U.S. Department of Defense. This means we meet the higher safety and quality standards required to transport military personnel.
