Stefanie helped me to find my inner self.
Brice Evin, CFO, Vodafone Ireland

My work has brought me around Europe, - ie - I lived in Denmark and Ireland for a number of years and now Luxembourg is my home. Because of this I have strong cultural awareness and really enjoy bringing together people from different backgrounds.

europe is my home

Born in the south of Germany, I come from an entrepreneurial family and I have always been interested in business. This led me to study business and I then specialised in Human Resources, a good fit for me, because it combines business and people. My HR career spanned over 15 years in a dynamic and global tech environment with roles in Germany and Denmark where I had global responsibilities. In 2013, I started my own business, applying what I had learned to advise and coach others. 

In May 2020 I joined one of the first Positive Intelligence Training courses offered to professional coaches as part of my own learning path. The timing could not have been better - it came in the middle of the pandemic. Since then, I became one of Europe's first certified Positive Intelligence Coaches. As an active PQ Coach member, I integrate the 6-week Positive Intelligence training in my work.  I saw the life-changing impact on myself, my work and my family. It is an honour to join my clients' learning journey and witness their development. 

I live in Luxembourg with my French husband and two children. I love nature, travelling, learning and applying new knowledge. 

My Life is all about change and Continuous Learning

I love enabling, helping, supporting and connecting my clients, particularly when it means increasing self-awareness, self-confidence, helping them manage change and using connections to solve problems and fill gaps.

I’m particularly passionate about professional wellbeing. I lost my father to mental illness and appreciate the importance of our mental health and wellbeing as we strive to innovate, create, achieve and succeed. This has inspired me to help others work and succeed in a health way. Everyone can choose a better way!
