First National Bank & Trust Company of Williston will be changing its name to First State Bank & Trust in early 2020. First National Bank & Trust opened its doors in 1926 as a state chartered bank under the name of Commercial State Bank. In 1934 the bank switched to a national charter. We are returning to our original roots as a state chartered bank, which reflects our mission of serving the residents and businesses in the surrounding communities of our North Dakota locations.
