In 1919 with $500 and a horse and wagon, brothers David and Ernest Horn set out to build a feed business in York County, Pennsylvania.

They did so with the firm belief that if they always took care of their customers like they themselves would like to be treated, they would prosper. And prosper they did, with a combination of outstanding quality and extraordinary customer service.

Today, Pennfield is still owned and operated by the Horn family with an unrelenting emphasis on old-fashioned values and customer service. Over the years, Pennfield has flourished, growing into a diversified national business, including high-tech feeds for horses, dairy cattle and other animals, and Ritter Food Service, which supplies fresh poultry, custom-cut meats, seafood, dry goods and frozen food products to area restaurants and farmers markets.
