Dubuque Bank and Trust, a subsidiary of Heartland Financial USA, promoted Lynn H. (Tut) Fuller to the position of market president. Fuller succeeds William Callahan, who was named president of Arizona Bank & Trust in Phoenix.

In his new role, Fuller will begin by overseeing retail operations, retail mortgage banking, marketing, operations and finance. He currently serves as Heartland’s corporate director of retail, where he oversees approximately 100 banking centers and $2.6 billion in deposits across 10 brands. Other responsibilities include oversight of Heartland’s Business Banking division, Contact Center, Consumer Product Development and membership on Heartland’s strategic council.

Prior to Heartland, Fuller was a case team leader at Bain & Company in Chicago.

“I know our employees and valued clients will be in great hands going forward with Tut joining the bank,” said Doug Horstmann, president and CEO of Dubuque Bank and Trust. “I look forward to Tut having a positive influence with the growth and expansion of DB&T in our marketplaces, both in the Dubuque area and Keokuk. He will be expanding his engagement in our communities, as well as with our customer base.”

Both Dubuque Bank and Trust and Arizona Bank & Trust are subsidiaries of Heartland Financial USA, a Dubuque, IA-based community bank holding company.
