I have just put this book down: The Trusted Advisor, by David Maister, Charles Green and Robert Galford. It was first printed more than twenty years ago — and, reprints and updates aside, it has lost none of its relevance since. A yellow umbrella on the cover. It first came up in passing over breakfast, mentioned by the chief people officer of one of my clients. She had used it to run internal workshops for her client-facing staff, and had found it relevant to service businesses generally — and to professional-services firms in particular. She wasn’t recommending it to me so much as thinking aloud about her own teams. But the title stayed with me, so I read it cover to cover. It chimed with conversations we’ve had as a family, around our own dining table — about how a client relationship runs far deeper than selling; how it rests on a connection in which someone places the high stakes of their business, or their money, in your hands.
Only afterwards did I notice the small, pleasing irony: a book about being a trusted advisor had reached me from the client’s side of the table. I’m glad it did.
The book’s argument is simple, and harder to live than it sounds. Being trusted has very little to do with being the cleverest or most knowledgeable person in the room. The authors reduce it to something close to a formula — trust built from “credibility,” “reliability” and “intimacy,” all sitting over a single denominator: “self-orientation.” Get the top half right and you are merely competent. It is the denominator that decides whether anyone actually trusts you. The more your attention is on yourself — your fee, your pitch, your need to look clever — the less you are trusted, however good the work. The authors are blunt that the hardest of the four to master is that last one: getting your own self-interest out of the way. The trusted advisor, in their telling, is simply the one whose attention is genuinely on the client and not on themselves. That is the whole umbrella.
A day or two after I finished it, I happened to pick up this year’s Accounting Today Top 100 report. I really wasn’t looking for a connection. I found one anyway.
The report’s headline is consolidation. The largest firms recorded a striking number of mergers last year — nearly double the year before — with private-equity money now flowing freely into the profession and the biggest names committing enormous sums to artificial intelligence. And almost every firm, asked about its strategy, said a version of the same thing: move from compliance to advisory, get closer to the client, become the trusted advisor. The report even names the theme outright — it calls this “the year of the client.”
So here is the paradox that kept me turning pages. The entire profession is racing to become the trusted advisor — at precisely the moment it is restructuring itself at a pace that strains the one variable the book says matters most. Mergers, integrations, earn-outs, platform roll-ups are, almost by definition, acts of self-orientation. They turn a firm’s attention inward — toward its own cap table, its own systems, its own consolidation — at exactly the moment everyone is vowing to put the client at the centre.
The report holds both answers to this, and I’ll give them to you the way it gave them to me — without the names, because the argument matters more than who happened to make it.
On one side are the firms taking outside capital. Their case is a serious one: money funds the people, the technology and the depth of service that let a firm look after clients better than it ever could alone. Technology, especially, can buy back the hours that then go to the relationship itself. In the language of the book, capital can lower self-orientation — it removes the scramble for resources that quietly distracts you from the work.
On the other side are the firms staying independent, and they argue on exactly the book’s terms. Large roll-ups, they say, pull leadership attention inward — toward integration and restructuring — and clients end up underserved and overlooked. Independence, they argue, protects the continuity and the closeness that a client actually feels. Strip away the positioning and it is the same sentence the book keeps repeating: do not let the denominator rise.
I have sat on three sides of this table — as the client buying the advice, as the advisor giving it, and now on the delivery side, building the capacity behind it. You might expect that to hand me a verdict. It doesn’t, and I am not going to hand you one either. The report declines to crown a winner; so will I.
Because the trust equation does not care about your ownership structure. It cares about where your attention points. I have seen independent firms grow comfortable and complacent, coasting on a relationship they had quietly stopped tending — high self-orientation wearing the costume of loyalty. And I have seen backed, scaled, heavily systematised operations stay genuinely devoted to the client, because someone at the top refused to let the deal become the point. Capital can lower self-orientation, or raise it. Independence can protect intimacy, or let it curdle into “we’ve always done your return.” Both models can hold the philosophy. Both can lose it.
So I’ll leave you where the book and the report left me — with a question, not an answer. When a firm grows, who is it growing for? Read the report, or look at your own firm, and answer that honestly, and you’ll know which ones have kept the umbrella up — whatever the cap table says.
We grow when our clients grow. The rest is just the weather.
The Trusted Advisor is by David H. Maister, Charles H. Green and Robert M. Galford (first published 2000; twentieth-anniversary edition, 2021). The consolidation figures and the “year of the client” framing are drawn from Accounting Today’s 2026 Top 100 Firms report. Views, and the umbrella, are my own.
