Sal. Oppenheim has a presence in neighbouring European countries in Luxembourg, Zurich, Geneva, Vienna and Salzburg. The Bank has also taken its first step into eastern Europe, opening a representative office in Prague on 12 November.
In 1973, Sal. Oppenheim and the Amsterdam-based bank Pierson, Heldring & Pierson formed Oppenheim Pierson International S.A., Luxemburg. Six years later, Sal. Oppenheim and Pierson acquired Schoop, Reiff & Co. AG in Zurich. Sal. Oppenheim ended the partnership in 1992 following the merger of Pierson's parent company Amro with ABN, in order to maintain a corporate culture that values the preservation of independence. The location, however, was not abandoned. Sal. Oppenheim then founded a new bank in Luxembourg, as well as one in Switzerland. In addition to the Zurich branch, the subsidiary has also been represented in Geneva since 2001.
Sal. Oppenheim opened a new branch office in Vienna in 2001. A further office was opened in Salzburg in July 2002, to reflect the cultural and growing economic significance of the Salzburg area.
Foreign activities were bundled in Luxembourg in 2003 with the foundation of a holding under the name Sal. Oppenheim International S.A.
