Adelheid has been working as a highly effective consultant for listed corporations with a global footprint for more than ten years. She supports her clients in tackling disruptive transformation processes in the financial area. Clients particularly value her honest and pragmatic approach.

When Adelheid is not working on a client project, she loves to spend time with her husband and extended family. As a formerly successful basketball player, she is a great supporter of the WWU Baskets Muenster team.
