Defense Lawyer in Cologne

When one should engage a defense lawyer

You or your company are charged with a criminal offense or an administrative offense, respectively?

In such a situation, it is important to have someone at your side, you can rely on and who commands his profession.

What makes me stand out as a defense lawyer

Seniority and Experience

I have been admitted to the bar since 1995 – first in Düsseldorf, later in Cologne. I have great seniority, and experience in criminal defense. This enables me to act at eye level with the police, the public prosecutor’s office and the court: extremely committed and – whenever necessary – combative.

Competence by specialisation

As a lawyer for criminal law in Cologne, criminal defense is my exclusive field of activity.

Please read the reviews by my clients.

Maintaining competence through further training

Since the successful completion of the specialist lawyer training for criminal law, I have been constantly fostering my special knowledge of criminal law – among other things by attending advanced training events several times a year.

How would I conduct your criminal defense?



At first: accurate determination of the facts by intense discussion with you, the client, comprehensive study of the files and, if necessary, own investigations.


Legal Analysis

In a second step: exact analysis of the material legal situation and reasonable assessment of the proceedings to be expected.


Defense Strategy

Finally: joint determination of how to proceed, in particular: the most promising defense strategy.
