Welcome Home to New Frontier Bank! The bank was founded in 1999 by a group of St. Charles County families who realized there was a need for a community bank in St. Charles County. New Frontier Bank was created and designed to create a new experience for customers and employees. Our bank branches were designed to allow customers to conduct their financial business with the privacy it deserves, while creating a friendly and inviting atmosphere that many bank lobbies just don’t offer. We have a saying that “You will experience the difference as soon as you walk through the front door.” Hopefully as you continue your online tour you experience the difference too.
