Cultural Management.

Riverside is led by Tanja Hollenstein together with Hans Peter Riegel. In our projects we work together with teams of specialists who bring in insights from the respective scenes and disciplines.


Tanja Hollenstein is a creative consultant, strategy and communications expert. She was in the management of renowned

PR agencies and, like Hans Peter Riegel, is involved in pioneering Web projects.


Hans Peter Riegel is creative director of the Riverside companies. He became known to a wider public as the author of biographies about Joseph Beuys and Jörg Immendorff, with journalistic articles about art and culture as well as his work as a media artist and filmmaker. He also has a great experience as a developer and producer of cultural events.
