The history of Shamrock Bank in Mountain View dates back to June 1, 1899, when Washita County State Bank was first chartered. In November 1900, the bank received its national charter and became First National Bank of Mountain View. Since 2002, we have proudly operated as Shamrock Bank, N.A.
For more than a century, we have served Mountain View and the surrounding communities. While technology has transformed the way we bank—and handshakes no longer seal loan agreements—our values remain unchanged. We are committed to meeting the financial needs of our community through strong, relationship-driven banking.
Today, that legacy continues with a focus on the future—combining modern banking solutions with the same local commitment and personal service that have defined us for generations. We look forward to visiting with you.
