All events are cancelled until further notice. We offer and support online events.
We contribute to the containment of Covid-19 with this measure.
The OCG office is open, please wear a mask and keep the distance. Please make an appointment for your visit, as our staff is partly in home office.
You can contact us by mail or phone.
Please support all government measures, do not spread any unconfirmed rumours and beware of phishing mails.
