Expertise and specializations
His practice focuses on administrative law, particularly environmental law. He advises and litigates in cases involving permits, enforcement, and subsidies, always bridging the gap between legal frameworks and practical reality. He remains active in immigration law as well, focusing primarily on complex cases for businesses and individuals.
This combination allows him to approach issues from a broader perspective, considering not only the legal standpoint but also the impact on an organization, project, or personal life.
Legal experience and areas of focus
Jeroen is often involved in cases where the correct course of action is unclear and various interests and regulations intersect. He assists clients with permit procedures, enforcement issues, spatial development projects, and strategic decisions regarding government agencies.
In immigration law, he advises on labor and knowledge-based immigration matters and assists individuals with family immigration and residency rights cases. This combination enables him to oversee the legal landscape and the interplay between regulations and personal or business interests.
Methodology and approach
Jeroen’s approach is analytical and structured, with a strong focus on clarity and results. He simplifies complex issues and clearly identifies which legal steps contribute to a solution.
In doing so, he considers more than just the law. He considers administrative relationships, timing, and the practical feasibility of choices. Litigation is used deliberately, not as a default route but as a strategic tool when necessary. Jeroen advises from both a legal perspective and the context in which your issue arises.
Innovation and development in the legal profession
In addition to his practice, Jeroen is actively involved in developing the legal profession. He focuses on legal technology and artificial intelligence (AI) to make legal services more efficient and accessible without compromising quality.
