About me


There is nothing more exciting than rebuilding and advancing a business!

25 years experience: living and working on four continents have shaped me.

Hands-on: Analysis and strategy are imperative, but success comes only through consistent implementation.

Consequent: Deciding for something also means doing something else later or not at all.

I am an international entrepreneur and executive: As an Master of Science in electrical engineering I have a sound technology basis. My interest in business administration led me right from the start of my career to the business side. Sales and project management for huge international projects, often with volumens in the hundreds of millions of EUR, were my main campus of fostering.

Since 2009 I have held service, EPC and general management positions in the photovoltaic industry: first at the Siemens Energy in the USA and Germany, then as CSO for IBC SOLAR AG and as Managing Director Europe in a US start-up.
