Quéribus Family Office
Quéribus Family Office was established in 2006 by Peter Nienhuis, leveraging his tenure at ING and professional certifications as a Register Belastingadviseurs (RB) tax advisor and MfN-registered mediator. The practice is anchored in the notion that Dutch entrepreneurial wealth requires integrated stewardship: legal planning around inheritance and family law runs alongside investment oversight, not as separate service lines. Business partner Tim Claes, associated with Realdolmen, operates alongside Nienhuis to extend the firm's capacity in structuring and permanent representation. The firm deploys capital across public and private markets, with confirmed investment activity concentrated in private equity, real estate, and direct co-investment structures. Its real-asset footprint is partially housed through Quéribus Vastgoed B.V., a dedicated commercial property vehicle registered in Houten. Geographic allocation spans Europe and North America, though specific portfolio company names are not publicly itemized. As of mid-2026, the firm maintains a deliberately lean operational structure — team size and total deployment figures remain undisclosed. It participates in the Vereniging van Family Offices (VFO), the Dutch family office association, reflecting peer engagement rather than a public marketing posture. No fund-of-funds or club-deal subscription programs are advertised; the organization emphasizes direct stewardship over discretionary portfolios for its client families. Structurally, the firm departs from a pure investment office model by embedding a certified mediation practice under the same roof. This dual capability — managing both the financial assets and the relational dynamics of wealthy families — distinguishes Quéribus in a Dutch market where succession often intertwines with complex inheritance law. The regulatory roof comprises RB tax advisory registration and MfN mediation accreditation, enforced through Peter Nienhuis's personal licensing rather than a standalone corporate charter.

Frequently asked questions
Who runs investment decisions at Quéribus Family Office?
Founder Peter Nienhuis oversees the firm's investment and mediation activities. As a former ING executive and a certified tax advisor, he combines banking experience with legal qualifications. Business partner Tim Claes adds capacity on structuring and representation, but the firm has not publicly named a dedicated CIO or separate investment committee.
How is Quéribus Family Office different from a wealth manager?
Quéribus integrates certified mediation services alongside discretionary portfolio management. This means it handles inheritance disputes, family law questions, and intergenerational planning directly — not through external referrals. In the Dutch market, where estate planning and family dynamics frequently collide, this structural bundling is unusual.
Does Quéribus participate in fund commitments or only direct deals?
The firm engages in direct co-investments and private equity, alongside real estate through its affiliated entity Quéribus Vastgoed B.V. Discretionary portfolio management spans both public and private assets, but no specific fund-commitment programs or external GP relationships are publicly disclosed.
What investment stages and regions does Quéribus target?
Quéribus allocates capital across private equity and real estate, with a geographic footprint covering Europe and North America. The firm does not publish stage preferences or minimum ticket sizes, consistent with its tailored, client-specific mandate rather than a standardized fund product.
How is Quéribus Vastgoed B.V. related to the family office?
Quéribus Vastgoed B.V. is an affiliated commercial real estate vehicle housed in Houten, Netherlands. It serves as the real-asset arm for client property holdings, operating alongside the discretionary portfolio management and mediation services delivered from the Nijmegen headquarters.
