Regulatory Strategy. Market Access. Executive Search. Governance.

Trusted advisor to the trading industry, providing support with regulatory challenges, licensing, senior hiring, and board-level strategy.

About me

What I Do for Clients

Regulatory Executive Search

I recruit (senior) legal, compliance, and regulatory risk professionals with deep expertise in EU financial markets regulations. Retained or contingent searches, discreet and effective.

EU Market Access and Licensing

I support non-EU firms through the licensing process in the Netherlands and the EU. This includes supporting the application process, preparing for AFM/DNB engagement, and connections to trusted local experts.

Non-Executive & Advisory Board

I am available for independent non-executive (INED) and advisory board positions, offering regulatory insight, governance and strategic oversight for firms active in trading, fintech, and regulated markets.

Why Clients Work with Me

What I Bring to the Table

With over 25 years of experience in financial markets, I bring a rare combination of regulatory insight, industry perspective, an extensive network and board-level judgement. I’ve worked as a policy officer and supervisor at the regulator and as compliance officer and ultimately as EU Head of Public Affairs at a major trading firm — so I understand the full spectrum of how rules are made, interpreted, and enforced.

Why my Clients Trust Me

Clients highly value my deep network across the Dutch and European trading landscape (both at the public and the private sector), my strategic approach to complex regulatory questions, and my ability to connect firms with the right experts — whether it’s for licensing, advocacy, or building a strong compliance team. I’m known for being independent, discreet, and results-driven.
