Elmhurst Bank

Elmhurst Bank operated as a division of West Suburban Bank, a community-focused financial institution serving the Chicago suburbs. It was dedicated to providing a full range of personal and business banking services, including checking, savings, loans, and mortgages, with an emphasis on local customer relationships. In late 2021, its parent company, West Suburban Bancorp, Inc., completed a merger with Old Second Bancorp, Inc. Consequently, all Elmhurst Bank locations were fully converted and rebranded to Old Second National Bank during 2022, and now continue to serve the community under the Old Second brand.
