About Us


Who We Are

Great Western Bank (NYSE:GWB) is a regional financial services company focused on business and agribusiness banking.

Headquartered in Sioux Falls, South Dakota, our banking model seeks to balance the best of being a “big enough & small enough” bank, providing capabilities typical of a much larger bank, with a customer-focused culture usually associated with smaller banks.

We rank as the 5th largest US farm lender (as of December 31, 2019) with more than 170 banking branches across nine states.
