Most principals, if asked to rank their hires by importance, would name the Chief of Staff, the Family Office Director, or the senior investment hire. These are large, visible roles. They carry titles that sound strategic.
The Personal Assistant is rarely on the shortlist for most important hire. That is almost always a mistake. The PA is the role closest to the principal, with the highest frequency of contact, the greatest access to information, and the greatest capacity to preserve or waste the principal's time. A poor PA degrades every other part of the operation. A strong PA makes every other part better.
This article explains why the PA is the highest-leverage hire a principal makes, and how to think about the role if the current PA is not delivering that leverage.
It is written for principals who have underinvested in the PA role, and for senior operators who are evaluating whether the PA on their team is as strong as the rest of the operation requires.

The PA sits at the intersection of everything. The diary, the inbox, the phone, the household calendar, the travel, the meetings, the filtering of access. More operational information flows through the PA than through any other role, including the Chief of Staff.
Diary. Every commitment the principal makes is booked, rescheduled, or declined by the PA. Over a year, the PA's decisions about what gets into the diary shape what the principal actually spends their time on. No other role has this leverage.
Inbox and phone. The PA filters what reaches the principal. A strong PA protects attention. A weak PA delivers noise or misses signal. The difference is hundreds of hours per year.
Access. The PA decides who gets through, when, and in what form. That decision-making carries real power, and it is made hundreds of times per month. Mistakes compound.
Continuity. The PA holds the through-line of the principal's life. Preferences, routines, recurring commitments, personal relationships, and the small details that keep the household running. A new PA takes months to absorb this. A strong PA who leaves takes the institutional memory with them.
The CV for a senior PA at UHNW level tells you about experience. It does not tell you about judgement. And judgement is almost the entire job.
A PA makes dozens of small judgement calls every day. Whether to interrupt the principal. Whether to commit to a meeting without checking. How to respond to a sensitive query. Whether to raise an issue now or at the next check-in. What to tell the housekeeper without checking with the principal first.
These decisions are invisible to most evaluation processes. Interviews rarely test them. References rarely cover them. And yet the principal's experience of the PA, positive or negative, is determined almost entirely by these decisions.
The erosion of trust in a PA usually starts with a small boundary call the principal noticed but did not mention. A piece of information passed on when it should have been held. A commitment made without checking. An access decision that turned out wrong. Any single one is minor. Across weeks and months, they compound into a loss of confidence that is almost impossible to recover.
Over a year, a strong PA delivers compounding time savings, judgement savings, and risk reduction.
Time. Hundreds of hours saved on scheduling, coordination, small decisions, and administrative load. Principals who describe their best PAs almost always describe time in the same terms: "they give me back my week."
Judgement. A strong PA pre-processes decisions. Options curated, not choices offered. Meetings prepared for, not just booked. Travel anticipated, not just arranged. The principal arrives at the decision moment with the work already done.
Risk. Strong PAs prevent mistakes. Double-bookings, missed commitments, poorly handled access, inappropriate disclosures. The absence of these mistakes is often unremarked. The cost of one serious one is substantial.
Reputation. The PA is the principal's interface with most of the people who interact with the principal. Advisors, contacts, staff, external parties. The PA's tone, speed, and competence shape how all of them experience the principal. Reputation effects accumulate quietly and durably.
Principals often spend disproportionate effort on hires that sound strategic and under-spend on the PA. The logic is understandable. A Chief of Staff or investment hire has visible output. A PA's output is mostly invisible. The principal does not see what the PA prevented or enabled.
The result is a typical pattern. The Chief of Staff is hired with care, references checked, compensation generous. The PA is hired more quickly, at a lower budget, with less scoping. Within twelve months, the Chief of Staff is functioning well and the PA is the bottleneck. Every decision the Chief of Staff tries to make runs through diary conflicts, access failures, and information gaps that the PA should be resolving.
The fix is to treat the PA hire with the same rigour as the senior hires. Proper scoping, a careful shortlist, calibrated compensation, and real judgement-testing during the interview.
The shape is specific. Not every skilled PA performs at UHNW level. The role demands a combination that is rarer than the corporate PA market implies.
High-capacity multitasking. Managing diary, inbox, phone, household, travel, and ad hoc projects simultaneously without dropping anything.
Proactive anticipation. Seeing what the principal needs before being asked. Reading the diary pattern, the upcoming travel, the next meeting, and preparing without instruction.
Absolute discretion. Knowing what does not get discussed, ever. The PA sees everything. The principal's comfort depends on total confidence that nothing will circulate.
Judgement under pressure. Making the right call in the moment, when the principal is unavailable to check with, and owning the outcome.
Low ego. Not needing to be seen, not competing for credit, not defining the role by visible success metrics. Strong PAs take pride in invisibility.
Stamina. The hours and the intensity are real. PAs who cannot sustain the pace drop out within twelve to eighteen months.
This combination is rare. Strong UHNW PAs are typically poached long before they reach the open market, which is why a specialist search is usually the only path to hiring one.
These are different roles, and conflating them is a persistent source of hiring errors. The PA is principal-proximate and lifestyle-integrated. The EA is office-anchored and business-coordinated. The Chief of Staff holds authority and closes decisions.
A PA who is asked to perform a Chief of Staff role will either stretch and fail or refuse and frustrate. A Chief of Staff who is asked to perform PA work will leave. An EA who is asked to perform both ends up doing neither well.
Decide what the role is, price it accordingly, and hire against the actual profile. The "one senior hire to do it all" approach almost never works above a certain scale.
A weak PA does not fail dramatically. The failure is slow and diffuse. Symptoms accumulate.
The principal starts managing their own diary. This is the clearest sign. When a principal is doing their own scheduling, the PA has failed at the core task.
Information gets passed incorrectly. Messages summarised wrong, priorities inverted, context lost.
Access decisions drift. The wrong people get through. The right people are delayed. Small mistakes embarrass the principal.
The household or office complains. Other staff find the PA difficult to work with, unresponsive, or inconsistent. The complaints reach the principal indirectly.
The Chief of Staff or senior operator spends time compensating. The CoS starts doing PA-level work because the PA is unreliable. This is expensive misallocation of a senior resource.
When these symptoms appear, the instinct is often to add more structure or hire an additional assistant. The correct response is usually to upgrade the PA.
UHNW-level PAs with the full profile earn £90,000 to £150,000 plus bonus in London. In the US, ranges are higher still. For principals with heavy international travel, multiple residences, or unusually complex lives, £150,000 to £200,000 is not unusual for a senior PA, with bonus upside.
The instinct to economise on the PA role is the single most expensive false saving principals make. A strong PA at £130,000 delivers vastly more value than a weaker PA at £70,000, and the gap compounds every year the role continues.
A short diagnostic.
Do you think about your diary? If you are making scheduling decisions directly, or your diary contains meetings you do not want to be in, the PA is not filtering at the level they should.
Do you feel prepared before meetings? If you walk into meetings without context, briefing notes, or awareness of what the other side wants, the PA is not anticipating.
Do people around you find the PA difficult? Consistent friction from multiple directions (household, office, external contacts) is a signal, not a personality clash.
Are small things dropped? Small administrative misses are the surface expression of deeper capacity or judgement gaps.
Does the PA raise issues to you proactively? A PA who only responds, never initiates, is not operating at a senior level.
If the honest answers indicate underperformance, upgrading the PA will return more time, attention, and reputation than almost any other operational change.
Oplu treats the PA hire as a serious placement, which in the UHNW segment it almost always is. Scoping covers the principal's actual day, the frequency of contact, the nature of the coordination, the travel pattern, the household, and the style preferences. Shortlists are small. Candidates are interviewed for judgement, not just capability. Reference calls probe discretion, proactive behaviour, and the small decisions that distinguish a strong PA from a competent one.
We do not throw CVs at clients. At this level, every CV looks strong. What distinguishes one candidate from another is style, judgement, discretion, and fit with the specific principal. Those require assessment, not volume.
The PA is the highest-leverage hire the principal will make, because the PA amplifies the principal. Every principal operating at scale has a finite amount of attention. The PA decides how that attention is spent. A strong PA spends it on the highest-value activity. A weak PA lets it leak.
Over a decade of a principal's professional and personal life, the compounded difference between a strong PA and an average one is measured in thousands of hours, dozens of prevented mistakes, and the durable reputation the principal builds through every interaction the PA touches.
This is why the PA is the hire that deserves the same care, rigour, and investment as the most senior roles in the office. And why Oplu advises principals to treat it that way.

Because the PA sits at the intersection of the principal's time, information, and access. Every diary decision, every access decision, and every filtering choice runs through the PA, and those decisions compound. A strong PA saves hundreds of hours per year, prevents mistakes, and protects reputation. A weak PA degrades every other part of the operation. No other role has comparable leverage over the principal's effectiveness.
