As one of the world’s largest conventional and organic oat millers, our legacy is built on being more than just an ingredient supplier. We are a proactive partner, working with others to do what’s right.

Grain Millers helps make food that is safe and healthy while adding value along the supply chain. A chain that is held together by people like you—farmers, millers, customers, and consumers—each of us grounded in a mission to bring healthy food to the table.

Our Farmers

We source a very large portion of our grain supplies directly from the farm. So it’s important to find meaningful ways to help support their operations beyond the price we pay. It’s simple: What’s good for our farmers is good for us and good for our partners.

This free, voluntary program is for any farmer who wants to become a sustainable grower, even if you’re not growing for us. Because we all benefit from good stewards of the land.

Food safety is our number-one priority, driving us to achieve some of the highest certifiable levels in the industry. Many consumers want their food more than safe, but also grown and/or manufactured in accordance with their values. We take that just as seriously. Delivering healthy food for healthy living.
