, which works with family offices, has appointed the former CEO of Thamesis, a single-family office based in London, as a partner.

The joiner, Paul Reynolds (main picture), who had worked in the CEO slot at Thamesis from 2010 to January 2026, is remaining as a senior advisor at the organisation. 

Westwick works alongside families at major turning points such as when they are being established, during a handover between generations or when a struggling FO needs to be set in order.

Partners at Westwick have run family offices from “the inside rather than advised them from the outside,” the firm said in a statement. 

“Paul has sat where the families we serve sit,” said Gilles Erulin, founder of Westwick Partners. “Inside the office, accountable to a family, not selling to one. That is rare. It is also exactly who we are.”

Reynolds will work with families based in the UK and other parts of Europe.
