Private Executive Assistance
for those who require no introduction
"The very best service is invisible — it anticipates, it acts, and it never asks to be noticed."
Our Philosophy
Berkeley Square was established to serve a clientele for whom excellence is not aspirational — it is expected. We operate at the intersection of discretion, precision, and world-class execution, supporting principals whose time is their most finite resource.
Our principals are post-money founders, generational wealth custodians, sovereign principals, and those who have quietly reached the summit. We exist so that nothing else requires their attention.
Our Standard
We do not advertise. We do not grow for growth's sake. Each principal is assigned a dedicated Chief of Staff — selected, vetted, and trained to mirror your exacting standards. Our team is drawn from the world's most exclusive private households, family offices, and intelligence agencies.
Access to Berkeley Square is by personal introduction or referral from an existing principal. There are no waiting lists. There are no compromises.
What We Do
Private aviation charter, yacht coordination, motorcade and armoured transfer arrangements across 90+ countries. Your aircraft briefed, your suite confirmed, before you've considered asking.
End-to-end diary management across multiple time zones and principals. Meeting preparation, pre-read synthesis, post-meeting action cadence — handled without instruction.
Oversight of multiple residences, seasonal preparation, staff management, and discretionary procurement. From the cellar to the helipad — consistently immaculate.
Coordination with wealth management, legal counsel, and corporate entities. Sensitive documentation handled with the same care as classified material.
Access to private dining rooms before reservations open. Foundation seats at opening nights. Invitations to closed events. The world arranged to your preference.
Advance route reconnaissance, protective detail coordination, threat assessment liaison, and digital privacy management. Quiet assurance, always.
"Not everyone is a client.
Not every client is a principal.
You already know which you are."
