Looking through someone else’s eyes will broaden the perspective and enhance both the question and the solution.

Josette de Goede

Josette de Goede has over thirty years of experience on the interface of strategy, leadership, and change. For example, she was managing director of executive education at the Rotterdam School of Management, director of international affairs at Management Center De Baak, and has been working both nationally and internationally as a change expert for years. She has two masters in Change Management (SIOO + HEC and Oxford University). Within The Change Academy she operates as change leader, coach, and teacher in leadership and change. In addition, she works as a moderator and as a supervisor at educational institutions and housing corporations.

 

Josette has a special talent for offering surprising and keen perspectives to generate movement in people and organisations. She has a particular eye for creating new realities: think out of the box and do the unexpected to achieve your goals. She passionately searches for new ways to organise and connect both poles and antipoles that fit in with contemporary questions. Josette uses a multidisciplinary approach for realising changes. She engages individuals and organisations by inspiring and empowering them in the context of their goals and prupose. This stems from her vision that real change does not occur top-down, but through those people who know why they are doing it and are capable of doing it. She therefore cooperates with very experienced experts from an international network. And she connects all of this on a deeper level with the underlying forces of life. "Seriously but with humor”.
