Modern legal advice means for me quick communication, uncomplicated solutions and accurate work. A large part of my work takes place digitally what enables me to operate from everywhere in the world if necessary.

On account of my bilingual education, I consult with many international clients who have legal issues in Germany.

As a son of two artists, finding creative solutions was handed to me from the cradle on. This and my international network of specialist which I could build up within the scope of my activities in European and international foreign countries are the base for my often-international legal advice.

It belongs to my passions to advice founders of new businesses with their jump into the cold water of self-employment and to help startups with the legally-compliant conversion of their projects.

If you want to be advised in a modern and efficient way, please send me an e-mail or set up a telephone appointment.

I will be glad to advise you in English, German, Spanish and Catalan.

I was born in April of 1990 in Berlin-Charlottenburg and grew up later in the “Harz” area and in Barcelona.


From 2007 to 2012, I studied law in Goettingen and Barcelona. At the age of 25 years, I received my doctorate from the University of Rostock. I finished my legal clerkship in Schleswig – Holstein with stations in Hamburg, Brussels and the German Embassy in Kuala Lumpur.


After my licensing as a lawyer in 2017 in Germany and Spain, I worked as a German lawyer in Barcelona.


Finally, in 2019 I joined the law firm Friederici and Partner in Hamburg. Here I am also responsible for our clients in Spain.
