Summary
I bring over 25 years of international leadership experience: in global corporations such as adidas and Reebok, as CEO of a mid-sized e-commerce company, and as a management consultant in the retail & e-commerce, sports & apparel, and supply chain & logistics industries.
I have led transformations from three perspectives: as a CEO with P&L responsibility, as a Global HR Executive responsible for leadership, compensation and organizational development, and as an IT leader responsible for systems, processes and execution.
I work with boards, executive teams, corporate functions and international project teams, in matrix structures as well as in international mid-sized companies.
My strength lies at the intersections where transformations typically fail: between strategy and execution, between headquarters and operations, and between leadership teams and employees.
