Mark Dieffenbach started making his own potato chips on his kitchen stove in Berks County, Pennsylvania. His chips became very popular with family and friends and a short time later, he built his own kettle cookers, which the third generation of the Dieffenbach family stills uses today. As the business grew, Mark needed larger fryers and expanded from his kitchen to a small plant in the garage—on this exact site.

Dieffenbach’s began churning out chips from the 10,000-square-foot addition to the factory on Host Road in Womelsdorf.

In addition to the original kettle chips, the company started to produce a separate brand of premium chips known as One Potato Two Potato. Introduced in 2013, the One Potato Two Potato line is designed as a healthier snack option.
