Independent. Experienced. Client-Focused. White Oak Management is a Luxembourg-regulated Professional of the Financial Sector (PSF), supervised by the Commission de Surveillance du Secteur Financier (CSSF).
We provide corporate domiciliation, company administration, accounting, fund administration and family office services to institutional investors, asset managers, private investment structures and entrepreneurial families.
Founded in response to a clear market need, White Oak was established to offer an independent, high-quality alternative to larger service providers. Our platform was designed for clients seeking a more personalised, responsive and relationship-driven approach to the administration and management of their structures.
Trusted to navigate what matters.
At White Oak, we believe that long-term partnerships are built on trust, accessibility and expertise. Our senior professionals work closely with clients to understand their objectives, support their operations and help them navigate an increasingly complex regulatory environment.

Our story
Recognising the growing demand for an independent boutique provider in Luxembourg, the founders of White Oak initiated the regulatory approval process with the CSSF in 2017.

In July 2018, White Oak received authorisation from the Luxembourg Minister of Finance to provide:
- Corporate domiciliation services, including bookkeeping
- Company incorporation and corporate management services
- Family office services
Since then, the firm has expanded its offering to include central administration services, investor servicing and fund administration activities.
Our growth has been driven organically through long-standing relationships with professional clients, entrepreneurial families, general partners and asset management firms who value our independence, expertise and client-centric approach.
