Dr. Alexander Koeberle-Schmid
His work is based on the premise that conflict in family businesses is the norm. His goal is therefore to promote understanding among the parties involved, in order to support them in finding common solutions to conflicts – or to develop strategies and structures to prevent conflict from arising in the first place. Therefore, the focus of his work is the conscientious guidance of families in developing solutions that all parties can agree on, so that they can orient themselves in the same direction and find harmony. Alexander Koeberle-Schmid acts from personal experience and incorporates it into every case individually. This helps him to develop sustainable strategies with the families and to help them avoid future conflicts.
Since 2005, he has advised family businesses and entrepreneurial families as an ownership strategy consultant, mediator (BM ©), and family business coach (ICF), with tenures at KPMG and PwC as well as INTES Academy for Family Businesses, with which he continues to collaborate today. He is the author of eight books and numerous studies on the topics of succession, leadership, and conflict resolution.

While at Egon Zehnder, Davy recruited hundreds of CEOs and executives for multinational and Asian corporations, for some of them he also led management appraisals and board consulting projects.
