50 YEARS. Please help us in congratulating Mike Harmon for reaching an incredible milestone with Wieser Concrete! Mike started off in production at our Maiden Rock plant in 1969, then worked as a truck driver, and later transitioned into the dispatcher role. He worked alongside Joe Wieser when the company was still in its early stages and has continued to help Wieser Concrete strive through his hard work and commitment throughout the years.
