Personal assistant vs. chief of staff: which one your life actually requires

Somewhere in the last decade, everyone's assistant became a chief of staff.

I see it weekly. A résumé crosses my desk with "Chief of Staff to UHNW Principal" at the top, and three questions in, the actual job emerges: calendar, travel, errands, correspondence, the dry cleaning and the dinner reservations. Honorable work, done well by someone talented. But it is a personal assistant role wearing a borrowed title.

The inflation runs the other direction too. Families post for a "personal assistant," then describe a role that supervises household staff across two properties, manages a renovation, and interfaces with the family's attorneys. They wonder why every candidate is either overwhelmed or overqualified.

After running these searches since 2002, I've concluded the confusion is rarely about vanity. It's that most principals have never seen the two roles clearly defined side by side. So let's do that.

The real dividing line: execution vs. ownership

Forget the titles for a moment and look at where decisions live.

A personal assistant executes. You decide; they do — quickly, precisely, and with taste. The calendar is immaculate. The travel is booked to your preferences down to the seat. The gifts arrive on time and feel considered. The measure of a great PA is throughput with polish: an enormous volume of tasks completed exactly as you would have done them, without your involvement past the initial ask.

A private chief of staff owns. You describe an outcome — "the move to the new house needs to happen by June," "our philanthropic commitments are a mess," "I want to stop being the router between the estate manager and the accountants" — and they deliver it, making dozens of decisions along the way that never reach you. The measure of a great chief of staff is what stopped requiring you.

Three practical tests separate them:

| | Personal assistant | Chief of staff | |---|---|---| | Who directs the work? | You assign tasks | You assign outcomes | | Do others report to them? | No — they coordinate | Yes — staff, vendors, and workstreams | | Can they represent you? | They relay your decisions | They make decisions inside delegated authority |

That third row is the sharpest test. When your attorney calls with a question and you are unreachable for six hours, a PA takes an excellent message. A chief of staff answers it — correctly — inside the authority you've granted, and tells you afterward.

Why the inflation matters

If this were just semantics, I wouldn't write about it. But mis-titled roles fail in predictable, expensive ways.

Hire a PA and call them a chief of staff, and you get a capable executor promoted past their authority. Household staff resent taking direction from someone who is, functionally, a peer. The "chief of staff" is blamed for outcomes they were never empowered to own. They leave, bruised, within eighteen months.

Hire a chief of staff for a PA's job, and you get an expensive strategist booking restaurants. They are bored by month four and gone by month ten — and genuine chiefs of staff are hard enough to find that burning one on the wrong role is a real loss.

Post an inflated title, and you attract inflated résumés, then spend the interview process unable to tell who has actually carried authority and who has carried a calendar. Title inflation makes everyone harder to evaluate, including the honest candidates.

There's a compensation cost too. A true chief of staff commands compensation well into six figures — appropriately, given the scope. Paying that for executed tasks is waste; offering PA compensation for genuine ownership guarantees you lose every finalist.

Which one your life actually requires

Here is the diagnostic I walk principals through. Look at your last bad month and ask what actually failed.

Things fell through cracks. Missed reservations, double-booked days, the passport renewal nobody caught, the gift that didn't ship. That is an execution gap. You need a personal assistant — possibly a spectacular one, but a PA. (If the work is anchored to your business life rather than your personal one, the answer may be an executive assistant instead; the same execution-versus-ownership logic applies.)

Things got done, but nothing connected. Every workstream — the properties, the household staff, the renovation, the foundation, the accountants — runs fine individually, and every one of them routes through you. You are the integration layer of your own life. That is an ownership gap, and no volume of task execution fixes it. You need a chief of staff.

Both. Common, at a certain scale of life. The answer is almost never one person. The hybrid unicorn who strategizes at nine and runs errands at eleven exists mostly in job postings; in practice one half of the role always starves. Hire the chief of staff, and let them hire the PA — it will be their first well-delegated outcome. Families whose complexity centers on investments and entity structures sometimes find the role belongs inside a family office instead; that is the family-office chief of staff conversation, and it changes the candidate pool entirely.

One honest caution: a chief of staff only works if you actually delegate. If every decision will still route through you — if authority is granted on Monday and reclaimed on Wednesday — hire the excellent PA, run your own integration, and revisit in two years. That is not a lesser choice. It is the right-sized one, and the people we place stay longest in right-sized roles.

Scope first, title second

The sequence matters: write down what failure looks like today, decide where decisions should live tomorrow, and only then name the role. The title should describe the authority, not decorate the posting.

If you would rather not untangle it alone, this is precisely the conversation we have with principals every week — before a single candidate is discussed. Tell us what your world looks like, and we'll help you name the job correctly. The right hire follows from there.
