My focus is on training and coaching in the areas of leadership, communication, change management, conversation techniques and efficient facilitation. It is important to me to communicate openly and on an equal footing, to understand people in the context of their actions, to strengthen strengths and to have a motivating and solution-oriented effect through direct practical relevance. For me, contemporary consulting means developing people and organizations in equal measure.
