Miller Grain Systems was founded in 1965 by Elmer and Alverna Miller on their family farm after neighbors started asking Elmer to have his 5 boys erect grain bins for them. In 1978, Miller Grain Systems added a GSI dealership and went on to be the #1 GSI dealer in the nation by 1982. At about the same time, GSI surpassed Butler to become the #1 bin company in the nation.

Miller Grain Systems has had the honor of being the GSI #1 dealer in Minnesota on multiple occasions.

Miller Grain Systems is still a family owned, full service grain storage and handling business providing bins, dryers, air systems, legs, augers and miscellaneous grain handling equipment.
