Arsenal Credit Union is a local, not-for-profit, federally insured financial institution in St. Louis, Missouri. It offers the same conveniences as large banks but provides better deals on loans and lower fees for individuals and small businesses. Customers appreciate the helpful and friendly staff at the branches, with some employees receiving high praise for their professionalism and patience. However, recent updates to their online banking system, especially the Android app, have caused frustrations, particularly with accessing Visa accounts. Despite these issues, the credit union has shown willingness to assist customers and address concerns. Overall, Arsenal Credit Union is valued for its community focus, better financial deals, and dedicated staff, though some users have experienced challenges with digital services.

I want to commend ACU and recognize Ryan Mayer for all his hard work, knowledge and keeping us informed throughout our loan process. This is truly a great financial institution.
