Our work is based on scientific research, content and methods are extremely transparent.
These are to be found in Dr. Kreggenfeld's publications, which include books, contributions to books and articles in journals.

In addition we've been distributing a newsletter for more than 11 years that informs on topics, trends dealing with communication consulting. We'd be happy to have you sign up for it. And we certainly want to assure you that we are very cautious in dealing with your data. Promise! The publications are unfortunately at this time only available in German.
We thank you for your understanding.
