Why Landmark?

“I entered banking in 1981 after being a business owner myself. Banking was a natural fit for both my Ag Econ degree and the business experience I had gained since college. Being a person who has been on the other side of the desk helps give me a better perspective. When Landmark National Bank was created in 2001 through a merger of two organizations, I had a chance to go to work for an organization that was going to be different in a very positive way from other banks. Landmark had a plan to grow and expand its ability to help clients be successful while continuing to be a community bank that cared about clients and their needs on a personal basis. Being able to help our clients and my fellow associates be successful is why I am a banker and is what inspires me each and every day.”
