BankingOhio, United States201-500 Employees

MainSource Bank operates in the banking industry and is based in Cincinnati, Ohio. The institution has merged with First Financial Bank and as a result, it now operates under that brand, with the First Financial Bank entity continuing the relationship with customers; the original account referenced is noted as inactive. The broader organization is part of a regional network that has engaged in community-focused initiatives, including partnerships and programs under the First Financial banner, with activity spanning across multiple states. The company’s presence includes a strong consumer and small-business banking footprint, supported by its status as a member of the FDIC and equal housing lender, and its regional profile is reflected in ongoing developments and recognitions reported through early 2026. A notable recent development is the continued expansion of the First Financial Bank brand and its community engagement efforts, including collaborations and local partnerships within the Cincinnati area and beyond. } }</n> } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } ) } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } } }
