For secure communication please use email or Threema

 

 

Please use e-mail or a messaging contact option. As we are often on the way, it is not always possible to be reachable by phone or skype. The personal conversation is very important to us and often the faster solution than email.

We are happy to arrange an appointment.

 

 

At the moment I'm on the way in the south Pacific, Internet is not always easy. I try to answer your request as soon as possible.
