In addition to the team of six permanent staff members and Felix Lehner—the initiator of the foundation—several people provide valuable work for the Sitterwerk within the framework of civil service assignments, as interns or volunteers.
The entire team of the Kesselhaus Josephsohn and the Kunstgiesserei, without whom the Sitterwerk Foundation would not exist, continues to be involved to a large extent and with great commitment to the success of the various Sitterwerk projects.
Sina Wider, Alanah Rüttimann, Nadja Tarnutzer, Maj Dörig and Lorenza Longhi support us in the supervision during opening hours on Sundays.
