Integrity & STrategy

Integrity matters most. Broad operational and strategic expertise through all levels of hierarchies allows me
to think and act strategically for the sake of the vision.


Governance, Risk & Compliance

Good governance is what protects our vision, our people and our crown jewels.

I go beyond regulatory compliance only – for peoples’ and companies’ security.



The interpretation of figures combined with the ability to communicate and negotiate is a highly valuable skill set.
In good times and crises. Also as a mediator.

more about Her


For all those readers who would like to know more about her – not business related but impacting who she is and what her values are.


It was her dream since early childhood to cross the atlantic on the seaway. So did she in 2008.

Strategy, Leadership and Crisis management at their best! Whenever possible she is on or at the water.


“I have to admit that I am a book addict. Reading is one of the luxury habits I practice every day. No matter how tired I am. Books allow access to the world, different perspectives and broaden the mindset.”
