Hans is someone who knows what he is talking about, he has a lot of experience and it shows. He has a great ability to adapt to the people present at the training. He is endowed with great behavioral intelligence. I applied the advice he shared with us and it worked great! Thanks Hans!.
Dear Hans. What have you done?!? For over a month now, I quit a very bad habit. I was skeptical in the beginning but admit that you blew me of my socks
Today, I followed one of Hans's training sessions at KPN, 1 word: amazing
