Plenty of firms in this space are one person with a good reputation. There is nothing wrong with that, and when it works it works well. But you should understand what you are buying, because it is not the same thing.
What one person actually means
It means one calendar. When that calendar is full, you wait. When that person is on leave, or ill, or has a client with a bigger problem than yours that week, you wait.
It also means a ceiling. However good they are, there is a size of problem they cannot take on, and you usually discover where that line is at the worst possible moment.
What we do instead
You get a named lead who runs your work and knows your business. Behind them is a backup who is briefed on you before you ever need them. Behind both is a bench of specialists for tax, legal and M&A.
So when the named lead is away, the backup picks it up and you notice a different name on the email, not a two-week gap. And when your work needs something specialist, we bring in a specialist rather than improvising.
How we keep it consistent
The obvious risk is that the work changes depending on who does it. We handle that with a written playbook and a review step before anything reaches you. Every submission we prepare is reviewed twice before it goes out.
That is a standard we hold ourselves to, not a promise about your outcome. But it is the mechanism, and you are entitled to ask whether we are keeping it.
What you give up
Honestly: you do not get one specific person on everything, every time. If what you want is a personal relationship with a single trusted advisor and you are content to wait when they are busy, a solo practitioner may genuinely suit you better.
What you get instead is that nothing stalls because someone is away, and there is no ceiling tied to one diary.
“You engage the agency, not one person’s calendar.”
A named lead, a backup who already knows your file, and specialists where the work needs them. The trade is less of one particular person, and far less waiting.
