## About

Roos van Diemen & Partners was established in 2007 by tax expert Bernadette M.J. Roos-van Diemen, extending her existing advisory practice into a structured multi-family office based in Rosmalen, Netherlands. The firm's wealth-origin is tied directly to that practice, serving affluent Dutch and international families with coordinated fiscal planning, estate structuring, and consolidated reporting across multiple banking relationships. The firm allocates client capital across private equity, targeting European buyout and growth-stage managers. Confirmed sector focuses include enterprise software, financial technology, digital health, educational technology, gaming, and human-resources technology. Rather than originating direct deals, Roos van Diemen & Partners acts as a selective allocator — vetting external funds, negotiating terms, and bundling family commitments to access institutional-quality managers. The firm's investment footprint is concentrated in Europe. Roos-van Diemen anchors the firm's professional network in the Dutch tax and accounting community. She serves as Secretary of the VLB, the Dutch association of tax and accounting firms, and writes regularly for Taxlive, a fiscal publication. The firm also maintains a connection to Stichting Top Institute Food and Nutrition, a research foundation. Team size and total deployment figures are not publicly disclosed. The firm's structural distinction is its origin inside a tax advisory — it integrates investment allocation with estate and fiscal planning at the family level, rather than operating as a pure investment office. This architecture means manager selection and portfolio construction are shaped by cross-border tax efficiency and succession considerations that a conventional family office might handle as an afterthought.
