A longtime executive for HTLF, one of Dubuque’s largest employers has expressed his disappointment in recent moves made by the financial services company and said it intends to move its headquarters to Colorado. Lynn B. Fuller, executive operating chairman of HTLF, recently submitted a letter to company leaders announcing his plans to retire from that position in May. He intends to retain his place on the company’s Board of Directors until his term expires in 2024. Fuller said a plan recently approved by the board to consolidate the company’s 11 bank charters into one charter based in Colorado will result in HTLF moving its headquarters to Denver by the end of 2023.
