The Grandpa Soap Co.

Woman-owned Business

The Grandpa Soap Company’s rich heritage started at the stove of Jess Hoffman’s farm in 1878, and extends through several generations of family ownership. Katherine Oliver Jarnigo and Molly Oliver Vollmer are co-CEOs of The Grandpa Soap Company, a family-owned business that is among the oldest continuously operating soap manufacturers in the United States. Both women grew up working in the business, which was previously run by their father. Over the years, a few things have changed, but the original dedication remains — to make simple, effective products for head-to-toe cleanliness. Today, the family and its employees continue to stand behind the quality of its products and value of its traditions.
