About Us

Our roots are planted right here in the Red River Valley, which makes it especially important for us to focus on this area’s ongoing financial health and continued growth. That’s why we spend our time and resources supporting the communities we serve here in North Dakota and Minnesota. This is our home too, and it has been for more than a century. Here is a little background on each of our branches:


United Valley Bank was founded in 1905 in Cavalier, North Dakota, 29 years after the town was established. Originally named Merchants and Farmers Bank of Cavalier, Pembina County Judge Robert McBride was the bank’s organizer and first president.

Through the years, the bank came under national ownership; it was later purchased by First Bank System and returned to its state charter in 1937. In 1987, the bank was brought back to local ownership when the local board of directors purchased it from First Bank System.

Grand Forks

In 1998, United Valley Bank opened its Columbia Road branch in Grand Forks, North Dakota. A large remodeling project gave the building more space and a stunning new look in 2014. A downtown Grand Forks branch opened in 2003.


Argyle State Bank was opened June 1, 1936 by local businessmen A.W. (Arvid) Carlson and A.L. (Tony) Carlson. Area farmers worked with the Carlsons to establish Argyle’s new bank, and the first Board of Directors consisted of A.W. Carlson, A.L. Carlson, C.G. Moline, E.I. Amundgaard and Joe Coninx. Arvid Carlson was the first president of the bank. Argyle State Bank continued to grow and serve the Argyle community under the ownership of the Carlson family until 2004, when it joined the United Valley Bank family.


Humboldt State Bank originated twelve miles north of Hallock, Minnesota. In 1943, the charter moved to Hallock, and the bank’s name was changed to Northwestern State Bank. In 2002, the bank was sold, and the name was changed to Marshall State Bank NA in 2003. In January of 2010, the Hallock location was acquired by United Valley Bank.


In the late 1970s, Minnesota began branch banking. It was at that time that Northwestern State Bank in Hallock, Minnesota, opened a branch in Lancaster, Minnesota. The Lancaster location became a branch of Marshall State Bank NA in 2003 after Northwestern State Bank changed ownership. In January 2010, the Lancaster location was purchased by United Valley Bank.
