BMO Harris Bank

Headquartered in Chicago, Illinois, BMO Harris Bank, is a result of a series of bank mergers after Bank of Montreal Financial group (Harris) acquired Marshall && Ilsley Corporation (M&&I) in July 2011. At that time, M&I Marshall && Ilsley Bank, M&&I Bank National Association (N.A.), and The Harris Bank N.A. merged into Harris N.A. Harris N.A. then changed it’s name to BMO Harris Bank N.A. Conversion of bank branches to the new look began in December 2011 and will continue until late 2012. Thanks to Stefan Bean for the tip.
