In a family office, "family" comes before "office"

The industry loves to present the family office as the backbone of family unity. It is the other way around. Unity makes the office possible. The office, at its best, reflects and reinforces it.

Why some families paused their private equity allocations in 2026

After a decade of every-vintage allocations, two of the families Westwick works with decided to sit out the 2026 PE vintage. The math, for long-horizon owners, has stopped working the way it used to.

Family business boards: hire competent directors, not just independent ones

How large families turn meritocracy from a slogan into a system: the induction program

"We choose on merit, not blood" is a common claim in family businesses. Very few families have the mechanism to make it true. One European family runs its next generation through an induction program that does.

Checkpoint for Family Members: Are you the owner of your wealth, or its custodian?

After twelve years on the board of Christie's, Westwick has seen both sides of the art market. For families, art is seldom a pure investment. It is a part of the family's soul, and it needs its own discipline.
