Paul Reynolds joins Westwick Partners

Sixteen years inside one family office, accountable to the family that owned it. That is the experience Paul brings to the partnership.

In brief

• Paul Reynolds has joined Westwick as a partner, announced on 22 September 2026.
• He was chief executive of Thamesis, a UK single family office, from 2010 to January 2026, and remains a senior adviser there.
• He works with families across the United Kingdom and Europe, on running the office, generational handovers and the investment questions an office has to answer for itself.

Running an office for one family means carrying all of it: the investment programme, the governance and the reporting, the relationships with the banks and managers around the family, and the succession questions when they arrive. Paul did that for sixteen years, accountable to the family rather than selling to it.

That is the distinction our work rests on. Families call us when something has to change — a handover between generations, an office that is not performing the way the family expects, or an asset that has drifted — and that work asks for people who have done it themselves. Paul has.

Outside his own office, he has chaired Institutional Investor's European single family office events for more than a decade, and fifteen years ago founded a members' club for family office executives that still meets. Before Thamesis he was a director at Sand Aire, a multi-family office, and spent ten years at Credit Suisse.

"Paul has sat where the families we serve sit. Inside the office, accountable to a family, not selling to one. That is rare. It is also exactly who we are."

— Gilles Erulin, founder, Westwick Partners

"I have spent my career inside single family offices. Westwick is the only firm I know that does this work hands-on, next to families rather than at arm's length. What we share is a simple aim: independent hands-on support, from practitioners with significant experience, to families facing complex and significant moments in their lives."

— Paul Reynolds

At Westwick he takes the mandates where the question is the office itself: handovers between generations, making sure the office runs efficiently, and the investment questions an office has to answer for itself. He works with families across the United Kingdom and Europe, alongside the existing partners.
