Professional Background

My Story
With a truly global perspective shaped by living and working across 5 countries — Switzerland, Belgium, France, USA, and Thailand — I bring cultural adaptability and operational expertise to every engagement.
Swiss Expertise
With experience at prestigious Swiss institutions — including the Geneva Graduate Institute and Sandoz Foundation Hotels in Lausanne — I am well-versed in the administrative rigor and professional standards that local clients expect.
International
What truly drives me is the why behind the work — supporting purpose-led organizations committed to ecosystem preservation, well-being, and human connection, through long-term collaborations built on trust and genuine cooperation.
