A Proven Past, A Fortified Future

Milk JugThe story of milk spills across centuries, and enriches lives on every continent.

The company we know as Dean Foods today was born in America's heartland more than 80 years ago. Over the years we focused our attention on becoming a "best-in-class" consumer products company. In 2001, the acquisition of Dean Foods by Suiza Foods Corporation of Dallas created a larger, even stronger company, which took the Dean Foods name. The "new" Dean Foods Company is the industry leader, poised for future success.
