Voices from real-life practice

Rolf Grünsteidl
Senior Sales Training Consultant,
Vodafone Headquarters Düsseldorf, Germany: 
"At Vodafone we have been working with the persolog tools for several years. I especially like the fact that with their help our staff reflect more frequently for themselves. Whether it is for personality, sales or leadership development: with each training session we learn more about how to get on better with colleagues and customers who tick differently."

Johannes Beck
DriveAcademy, SEW-EURODRIVE GmbH & Co KG:
"In our experience, those staff who are more aware of their own personality are more successful than others. For this reason, we use personality profiles as a supporting measure in staff development during training and in counseling. All staff involved in development measures have taken part in certification for the DISG profile."

Prof. Dr. Dr. habil. Kurt Nagel
Author, owner of the Systeme für Erfolg (Systems for Success) and Medien für Erfolg (Media for Succes) companies, Sindelfingen, Germany: 
"Two points convinced me with persolog: the scientific basis of the instruments and their effectiveness in practice. Definitely to be recommended!"

Prof. Dr. Bernd M. Mayer
Fachhochschule Amberg-Weiden, Germany: 
"I have worked for many years with the persolog instruments, initially just in industry and today also at Amberg-Weiden University. They are technically well-founded on the one hand and on the other I have experienced excellent practice-related results with them. My students tell me again and again of wonderful aha experiences. And it is wonderful to see that they actually use what they have learned."

Prof. Dr. Lothar Seiwert
Bestsellerauthor, Heidelberg, Germany: 
"Many inter-personal problems disappear if we really make the effort to understand others better. Persolog makes a valuable contribution to this."
