West Suburban Bank

West Suburban Bank was established on April 27, 1962, originally under the name West Suburban Bank. Over the years, the institution underwent several significant changes and expansions. On November 22, 1971, it officially adopted the name West Suburban Bank. The bank's main office was located at 701-711 South Westmore Avenue in Lombard, Illinois, which became its designated address in 1974. In a major expansion effort on May 16, 1997, the bank acquired multiple branches, including West Suburban Bank of Aurora in Aurora, Illinois, West Suburban Bank of Carol Stream/Stratford Square in Bloomingdale, Illinois, West Suburban Bank of Downers Grove/Lombard in Downers Grove, Illinois, and West Suburban Bank of Darien in Darien, Illinois. On March 31, 2006, the institution formally changed its name to West Suburban Bank. In subsequent years, the main office relocated to 701-711 South Westmore-Meyers Road, Lombard, Illinois, on March 29, 2021, followed by another move to 701 Westmore Meyers Road in Lombard later that year on June 29. Ultimately, on December 1, 2021, West Suburban Bank merged with Old Second National Bank, headquartered in Aurora, Illinois, marking the conclusion of its independent operation.
