Allister Fabricating Co. was founded in Milwaukee, Wisconsin on June 1, 1965, by the late John W. Allister with just three employees. In October 1965 the company moved to its present location in Lannon, Wisconsin. The original building and office was comprised of a total of 5000 sq. ft.. Today it has grown to over 51,000 sq. ft.. Our address is 21319 W. Good Hope Road, Lannon, WI 53046. On December 3, 1993, Gregory S.Sieckert obtained the company from Mrs. Allister and renamed the company Allister Fabricating, Inc. We have since purchased several machines and have added a third building. Please see our machinery page for specifications.
