Jess on Building Business Savings

My Story

As Branch Manager and Business Development Officer at our O’Fallon, MO, banking center, I provide exceptional customer service to personal and business banking customers. I excel at helping business clients understand our service options by analyzing their accounts and advising them on the best solutions, from business savings to payment and withdrawal processing, credit cards, merchant services, and digital banking. I take pride in helping business owners identify growth opportunities, building strategic partnerships and fostering relationships to expand their savings portfolios.

Business Savings Specialist, Mom, Dancer, Swimmer

I joined the bank in 2012 after attending the University of Central Missouri in Warrensburg, MO. With vast experience in customer service excellence, I have held various positions of increasing responsibility within our retail banking division. I am actively involved in the community through the O’Fallon Chamber of Commerce & Industries and the Parkway South Alumni Association. Outside of work, I love spending time with my son, traveling, dancing, swimming, photography, scrapbooking, going to parks, and having picnics with my family.

By being available and approachable, you are creating a banking experience that establishes loyalty and builds legacy.
