President & Chief Executive Officer
Citizens Bank of Edmond
Jill Castilla began her banking career with Citizens Bank of Edmond in 1998. Her progression then took her to the Federal Reserve Bank of Kansas City where she managed multiple departments from check automation to HR for nine years. She then joined the senior management team at a Minnesota community bank. Prior to Castilla's employment at Citizens, she served in the U.S. Army and Oklahoma Army National Guard. In 2009, she rejoined Citizens and served in the positions of Chief Credit Officer, Chief Operating Officer and Chief Financial Officer until 2014 when she was appointed to her current position. She is the 4th generation of ownership and management at Citizens.
Castilla has implemented several initiatives to communicate the mission of Citizens Bank and build on its relationship with the community. Under her leadership, Citizens Bank of Edmond introduced the Cash Mobs leading up to Small Business Saturday in November 2013 and have been doing them regularly since then. Citizens provides its staff money to shop at a particular small business on a given day and uses social media to promote that business. This helps support small businesses directly, where it matters, and lets them know that Citizens Bank of Edmond is not just a lender -- we are customers, too.
In 2013 and 2014, under Castilla's direction, Citizens Bank of Edmond began shooting YouTube videos in which staffers took popular songs such as Psy's "Gangnam Style" and Lorde's "Royals" and wrote new lyrics that reflected our attitudes and philosophies about community banking. These videos went viral and helped establish our reputation as an accessible, innovative bank that is customer focused. And in September 2014, Castilla launched Heard On Hurd, a monthly street festival in downtown Edmond featuring local food, music and shopping. The first two festivals attracted 4,000 and 5,500 people, respectively, and underlined Citizens Bank of Edmond’s commitment to its hometown.
Castilla is the public voice and face of Citizens Bank of Edmond and takes an active role in the bank’s social media messaging. Her proactive and progressive stance as a community banker makes Castilla an important voice in banking on a local, regional and national scale, prompting American Banker Magazine to name her one of “25 Women to Watch” in October 2014.
In the past year, Castilla was named by Independent Community Bankers Association as a top social media influencer and received the Woman of the Year award by the Edmond Chamber of Commerce. She is a graduate of the University of Wisconsin-Madison's Graduate School of Banking and has a Master's in Economics from the University of Oklahoma. Castilla is a recipient of the Distinguished Alumni Award from Hawaii Pacific University where she earned a BSBA in Finance. Castilla serves on the boards of directors for Oklahoma Bankers Association and Community Bankers Association of Oklahoma as well as trustee for UCO Foundation and Edmond Public Schools Foundation.
