Shamrock Bank began operations in Clayton in November 1995, continuing a legacy of stable, community-focused banking that dates back to 1918 with The First State Bank. Renamed Clayton State Bank in 1922, the institution served the community for decades before becoming part of Shamrock Bank, N.A. Since then, we have remained committed to delivering reliable financial solutions and exceptional service. Our banking platform combines modern technology with a distinctly personal touch, delivering a seamless, secure experience that gives customers, wherever they are, unmatched, around-the-clock access to their finances.
In Clayton, we live out our motto: “You are more than a customer, and we are more than a bank.” We look forward to serving you and helping you achieve your financial dreams.
