Coronavirus (COVID-19) Update
The health, safety and well-being of our customers, employees and communities continues to be our top priority.

Who We Are

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

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