Mariëlle de Macker

Every successful person had one or more people in their lives who believed in them, and who were willing to “take the bet.” I was lucky enough to have a few of those as well. They made me aware of blind spots that would at some point become a showstopper. At the same time, they helped me to leverage key qualities. Sometimes subtle, sometimes brutally honest and direct. Always with generosity and compassion. As a coach, I wish and work to be that trusted advisor and help leaders become the best version of themselves.
