Testimonials

“Books on leadership risk to exaggerate either in theory or in storytelling. de Summa is different. For those who fear theory, there are a lot of small cases and hints, and for those who are a Leo Neelslittle suspicious towards cases only, there is a continuous conceptual flow that stands in its own right.

de Summa is a rare combination of insight and experience, of pragmatism and analysis, of sharing praxis and building understanding of the underlying dynamics. Moreover, de Summa is written in a vivid and fluid semantic style that incites the reader to turn the pages.”
Prof dr Leo NEELS, President Press Agency Belga, President Adv. Board AMS Family Wealth Institute.

Francis Arickx, Directorate Head, National Institute for Health & Disability Insurance; Lecturer Health Policy, University Antwerp.
