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.

She has accompanied the Sitterwerk Foundation with her camera since its beginnings, and has thus assisted the Sitterwerk in creating its very individual visual presence in printed materials and on the Internet.
