What makes me stand out as a defense lawyer

Seniority & Experience

Since 1995 I have been admitted to the bar – first in Düsseldorf, now for many years 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 & Reviews

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

Maintaining competence through constant 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 Objective & Defense Strategy

Finally: joint determination of how to proceed, in particular: realistic defense objective and appropriate defense strategy.
