Continuing the family legacy, John Gleeson assumed the presidency of W.A. Klinger in 1983, bringing a fresh vision to the company's operations. His leadership marked a new chapter of growth and innovation for the firm, solidifying its reputation for quality and reliability. 

The construction of the Terra Building in 1983 was a pivotal moment for downtown Sioux City. Standing at 162 feet with 10 floors, this 181,000-square-foot office building was originally the headquarters for Terra Industries. W.A. Klinger's work on this modern, functional space reinforced the company’s commitment to innovation and its role in revitalizing Sioux City’s business district.
