VHT - Telephone directory

Dear business partners,


We wish to inform you that we are at your service without constraints!

But home office based.


You can get in contact with us as usual. But to ensure swift recalls in case of missed calls, we would strongly recommend to call us directly on our mobile phones!

Calls to our office landline phones are automatically forwarded, but cannot be traced if a call is missed.


Respective mobil phone numbers please find on our home page under: as well as on the attached list.

Or alternatively send an email to the requested contact.


Take care of yourself and stay healthy!
