I am working at Libertas Advocaten, a boutique law firm that focuses on matters regarding liability in criminal law or sanctions in administrative law. I mainly handle fraud, money laundering and economic criminal law cases, including environmental criminal law cases. In addition, I am also specialized in traffic cases. I represent both (large) companies and natural persons.
I regularly write juridical blogs and columns and I am a permanent contributor to the Journal for Sanctions Law & Company (Tijdschrift voor Sanctierecht & Onderneming).  
I am a committed lawyer and always strive for the best result for my clients.

I studied Criminal Law & Constitutional and Administrative Law at Leiden University. Following my graduation in 2013, I taught Criminal and Criminal Procedure Law at this University.
