Derk-Jan is an experienced and passionate Trainer, workshop and game leader. He always puts a lot of effort in getting his message across. His training style is open, informal and interactive. He likes to paint the whole picture, but is not scared to go into technical detail if that is required to make the tips and theory applicable in daily practice.
He creates a friendly atmosphere where people are free to make mistakes and be themselves. This enables him to challenge the participants and try new things. He find this important because each training, workshop or game should be both educational and fun.
