Friedbert Gay – CEO persolog

How can people cooperate more efficiently? This is the question Friedbert Gay has been dealing with for many years as managing director, master trainer and speaker. His philosophy is to be responsive to individual personalities because he is convinced that “the equal treatment of unequal people is not fair”.

„One that jumps into unknown fields often reaches higher levels” If you ask Debora Karsch by which motto she is inspired and which guidelines she has in her professional life, this is what she will answer. And this is why: She is convinced that real development is only possible if you try out something new. Of course you risk a short step back but in the long run Debora Karsch is convinced that courage and energy will pay off.
