Independent Alliance Banks, Inc. was formed in 2005 by consolidating the holding companies of Grabill Bank and MarkleBank, but leaving the separate identities of the individual banks. Both banks were successful in providing quality products and services to customers as well as being pillars of strength in the communities they serve. The two banks consolidated into one and formed iAB Financial Bank in 2012. A new bank name helped the company better address its corporate culture as it continued to grow and expand its franchise. The previous bank names were geographically limited and had roots in unique communities – Grabill and Markle. As the company realized growth that took it outside of those communities, it only made sense for the company to take on a stronger brand that did not limit its boundaries.
iAB Financial Bank is nearly $1 billion in assets with 17 offices and 275 employees.
