For over 70 years, Union Bank has enjoyed the reputation of being a solid bank which supports our communities. Union Bank’s first foray into branching began in 1989 with the opening of our Mulliken office. In 1993, we entered Barry county with a branch office in Freeport. Since then we have added Dimondale, Pewamo and Westphalia to our services areas, until most recently opening a branch at 400 W. State St. in Hastings in 2006.
