About Land O’Lakes :

Land O’Lakes, Inc. is a 100-year-old farmer-owned cooperative originally formed with the purpose of working together to create new market opportunities for dairy producers. Our journey began in 1921, when 320 dairy farmers met in St. Paul, Minnesota, to form the Minnesota Cooperative Creameries Association. Their idea was simple : join together to effectively market and distribute members’ dairy production across the country. Today, our four businesses give us a farmer-to-fork view of agriculture. Paired with our co-op ownership model, we’re uniquely qualified to fulfill our purpose of feeding human progress. We’re looking for big thinkers and big dreamers to help us imagine the future of food and agriculture.

Be a part of a Fortune 500, $17 billion farmer-owned cooperative that is actively shaping the food and agriculture industry for the better. Join us in solving some of the world’s most important food challenges.
