Our firm was founded in 1958 by Dr. Helmut Wagner, who operated as the sole lawyer for 13 years. The eponymous partners of the current law firm, Dr. Roland Dieterich and Dr. Andreas Maier-Ring, joined in 1971 and 1988, respectively. In 1982, Dr. Thilo Wagner took over from his father as partner. Since then, Wagner, Dieterich, Maier-Ring has continued to grow and has developed into one of the leading law and notary's offices in the greater area of Ravensburg. We currently represent the interests of our predominantly medium-sized clients inside and out of Germany with a team of 11 lawyers and specialist lawyers, among them eight partners.

In the 18th century, the office of Thurn-und-Taxis Post was also housed in the building.
