Arnold Timmerman works at the interface between personal and professional development, where the biggest struggles regarding change and transformation take place. His main passion is to provide people and organizations with support at the most turbulent times, focusing especially on human experience and expression as they evolve under pressure. Having worked in depth with groups of 10-500 all over the world, he brings comprehensive cross-cultural experience to bear on his facilitation, training, consulting and coaching work. Thanks to his interest and speciﬁc background, Arnold’s work bears most fruit where gaps between generations X and Y, between soft and hard skills, between the personal and the professional, between entrenched views and new inspiration need to be bridged. When it comes to addressing individual or collective challenges, the change he facilitates tends to be quick and lasting, because he homes in on root causes rather than treating symptoms.
