Lois Aller was a pioneer of sorts: one of the first Wisconsin residents to take up dressage, in the 1960s. Impressed by a dressage demo that Aller gave in 1971, a group of people decided that the state needed an organization to promote the sport. With around a dozen members, the Wisconsin Dressage Association was born.
When Lowell Boomer approached WDA about being a part of a nationwide dressage association, USDF had its support, and WDA became a charter GMO.
In 1986, the club expanded to provide more opportunities for the growing number of members involved in combined training, forming the Wisconsin Dressage and Combined Training Association.
