Dr. Aaron Mohr, O’Fallon Pain Relief Associates

Thanks to First State Bank, I was able to purchase my 1st commercial property. They used the Missouri First program combined with the SBA 504 loan program which had low interest rates and only required a 10% down payment from me. I would not own my building today if it were not for First State Bank and the programs mentioned above. They were able to secure the financing and get the job done, where other banks could not. Their level of care combined with their competency makes them unmatched in their industry. They simply are THE BEST!

First State Bank has played an important role in the growth and success of Masterclock as a global leader in the timing industry. From business checking, lines of credit, and Missouri’s liked deposit program to employee HSA accounts, FSB has always offered outstanding service for our company and employees. FSB’s business online makes managing various accounts a seamless process. As a local manufacturer, woman-owned, small business and an exporter worldwide, Masterclock continues to bank on First State Bank.

I knew that I was a good financial risk, but because of some past errors, my credit rating didn’t show that. Mark was able to navigate me through the options and give professional advice on how to best manage the situation. I had been to another mortgage lender and they didn’t offer any real advice on how to tackle my issue. Mark looked at the whole picture, explained what he could and couldn’t do, walked me through the confusing mortgage world and what ratings companies are looking for to increase a rating. His experienced advice was invaluable.

Everyone knows us when we walk in; we feel very welcome and understood. If it wasn’t for First State Bank, I would not have had the means to start my business. We always tell friends and family to choose First State Bank because of the small town feel, friendly staff, and because of the opportunity they gave us.

My parents banked with First State forever. When I took over their finances as they aged, I was impressed with the service and efficiency, the friendly staff, and the extra care, all of which convinced me to bank here also. They provide all services with efficiency above and beyond expectations. It’s actually a pleasant experience to bank here rather than a chore. I recently had an issue that necessitated closing one account and opening another…the staff took care of it all without a hitch. They were so reassuring, efficient, and congenial that all stress was whisked away.

I have never met a mortgage lender that works as hard as Matt Maassen. Day, night, weekend, or weekday, he’ll always answer his phone. He is always there for you. We had nightmare housing scenario turn into a dream, all because of Matt. We are truly blessed.
