Alerus Financial Corporation, marketed as simply Alerus, is a chain of financial institutions headquartered in Grand Forks, North Dakota, with locations in North Dakota, Minnesota and Arizona. Alerus offers banking, mortgage, wealth management, and retirement services. Alerus Financial's history dates back to August 29, 1879, with the formation of the Bank of Grand Forks by Mr. S. S. Titus. The bank was the second bank chartered in Dakota Territory. At the time, the bank was located in the back of a smokehouse on South Third Street in downtown Grand Forks. The bank quickly outgrew its building and moved into a new brick structure at the corner of South Third Street and Kittson Avenue.
