According to the actual pandemic situation, we decided to reduce our telephone presence:

At the moment, you can reach us from 10.00 a.m. to 16.00 p.m.
(with a break from 12.30 a.m. to 13.30 p.m.).We try to answer your call also outside these hours.

Nevertheless, it's best if you depose your question via email, where we can read and answer it all day.

If you like to visit us in person, we would appreciate it, if you could let us know in advance. This way we can ensure your ideal contact person will be on-site.
