Even after a long day of moderating, he still stood on stage at 11 p.m. radiating positive energy.”
Elke Vollmer, Hobart GmbH

“What incredible luck that we found Simon. An international congress with more than 600 participants and 40 speakers from 45 nations. Moderation, panel discussions, keeping presentations on time, award ceremonies, spontaneous translations – Simon had everything under control. His preparation was outstanding. Simon invested a great deal of time to familiarize himself with the subject matter and to get to know the different speakers and their specialist areas. This enabled him to ask the right questions to the right person at exactly the right moment. The questions he developed after preparing for this highly unfamiliar topic were precise and thoughtful. It never became boring with him, yet he always knew when to act with restraint and great respect. The participants praised him highly, and he played a major role in making the congress such a success. Simon moderated the entire event in English, which was absolutely effortless for him.”
Meike Dornieden, Organizer of TongueTime 2026 in St. Gallen
