Jack De Vringer

‘The trouble with having an open mind, of course, is that people will insist on coming along and trying to put things in it’ a quote by Terry Pratchett.  An open mind is a well needed start in improving performance, where my role is to try and get your mind to wander and actively take from the training those parts that fit.

Jack’s style is to apply the theory in practice, work together, actively and focus on personal development points.  Practice to experience effects of different behaviour, strengthen a growth mindset and achieving an increased knowledge about one-self.

Jack was both days very enthusiastic and clearly passionate about what he taught us. He brought his positive energy to the rest of the group and could thus create an atmosphere where everyone felt at his/her convenience and therefore dared to be open. His interactive style of training I liked very much, you kept thereby constantly alert and involved. Walking outside after lunch, while discussing/planning the topics … genius! I wish every trainer did this.
