Welcome - Established 1948 The Wisconsin Antique Dealers Association (WADA) is a non-profit organization dedicated to preserving our heritage in the State of Wisconsin. We strive to provide an ongoing education for our member dealers and the general public. The organization also has a history of providing grants to historical and heritage societies throughout the State of Wisconsin, helping them continue their missions of preservation. WADA sponsors two quality antique shows each year on the first weekend in February and October. The shows are held at the Waukesha Expo Center in Waukesha, Wisconsin, just west of Milwaukee. WADA dealers may do business through antique shows, antique centers and malls, individual shops, mail order, and appraisal services. On our site you can find detailed information on our members, the two WADA shows, and other items of interest.
