You already have a team. This is the layer underneath them.

Your team runs the family's affairs. We provide what a team inside a family cannot easily provide for itself: an audit of costs with no relationship to protect, a policy file enforced by software rather than by memory, an independent chair for the committee, and deal analysis capacity that does not have to come out of your principal's week.

Independence is not a criticism of your team. It is the thing your team cannot supply about itself, and the thing trustees and next-generation family members increasingly ask for.
