Diana McDougall, a founding member of the CSB team, has announced that she will be transitioning from her role as Lowcountry Regional President to serve as Community Engagement Officer for the Bank in the Lowcountry.

“It has been an honor and a privilege to serve our clients and communities since CSB’s formation in 2004,” said McDougall. “I am so proud of our team and our many accomplishments over the years. While I have reached a point in my career where I am ready to take a step back from a leadership standpoint, I am thrilled that I can continue to represent the Bank and help continue to drive our growth in the Lowcountry.”

“Diana has played a tremendous role at CSB for more than 20 years. From growing our branch footprint to building key relationships in our community, our team has the utmost appreciation for her service,” said Stone. “We are excited that Diana will continue to be involved in CSB as she begins this transition.”

Jeremy brings nearly 20 years of experience in banking and finance with a strong record of success in strategic growth, relationship-building, and community-focused service. His deep understanding of the financial services industry and commitment to local business development make him a valuable asset to both the Bank and the clients it serves.

“We are thrilled to welcome Jeremy to the Coastal States Bank team,” said Brian Smith, Coastal Regional President. “In his role as Market President, Jeremy will lead our growth strategy in Savannah—expanding the Bank’s presence, fostering meaningful client relationships, and delivering the high-quality, personalized service that has become the Bank’s hallmark.”
