Due to the COVID-19 situation, we converted our physical congress into a digital event with virtual exhibition within only 4 weeks. I would like to thank Congrex Switzerland for the professional organisation of our congress at short notice. I was always able to express my concerns directly, which were implemented with great commitment and to my complete satisfaction. We have received plenty of positive feedback for the digital medArt. This success was only possible with a dedicated, fully motivated congress team.
