Maarten Andriessen is a Founder at Mapwave at Vrije Universiteit Brussel. He possess expertise in change management, hr consulting, human resources, organizational development, talent management and 12 more skills. Colleagues describe him as "When you’re nearing your 50's and back at university for an in-depth part-time post-graduate program on management of health care institutions, you are particularly pleased with guest lecturers and visiting professors who have profound knowledge of their field of expertise and who have the ability to transfer that knowledge in an effective way using interesting presentations and useful practical examples and who are able to draw your attention to new insights and complementary explanations or clarifications of old and new theoretical models. The enthusiasm and educational quality of the lecturer makes the difference between 7 and 11 pm after a day’s work. Maarten definitely belongs to the group of guest lecturers who have the talent to, so to speak, "entertain" their students till late in the evening with theories and models and their use in practice." and "Maarten is an enthusiastic and engaged coworker. He excels through his profound insight into the processes that occur in organizations. Taking an action research approach, he managed to launch an organization-wide debate on how to improve internal cooperation. Despite the many thorny problems characteristic for organizational change projects, he managed to establish lasting changes in how organizational members relate to, and interact with, each other. I believe that Maarten is and will continue to be a trendsetter in organizational change. His efforts were rewarded with praise by the head of the Human Resources department."
