The Riches Are in the Niches: How Physicians Pick One Without Shrinking Their Practice
By Mike Woo-Ming, MD, MPH
Ask a physician who they help and you'll usually get some version of "anybody who walks through the door."
I understand the instinct completely. You spent years training to handle whatever shows up. Turning people away feels like the opposite of the job. And there's a quieter fear underneath it — that if you narrow your focus, you'll have a smaller practice and a smaller income, and you'll have done it to yourself.
I've watched it go the other way often enough to say it plainly: the riches are in the niches. Narrowing is usually what makes the practice bigger, not smaller. Let me show you why.
Two dermatologists
I know two dermatologists. Both board certified. Both roughly a decade in practice. Both tremendous credentials. Both offering, on paper, the exact same set of services.
One of them describes herself as a dermatologist. She's good. Her schedule is a grab bag, her referrals come from wherever, and her marketing — when she does any — says things like "comprehensive skin care for the whole family."
The other one is known, in her city, as the person to see for adult acne in women over thirty. That's it. That's the whole positioning. She still does everything else a dermatologist does. But when a 34-year-old woman in that city finally gets fed up and starts searching, she finds one obvious answer.
Guess whose schedule fills further out. Guess who charges more, works fewer hours, and has patients driving ninety minutes past three other practices to see her.
The difference between them isn't skill. It's that one of them is findable and the other one is a category.
Being specific is what makes you choosable
Here's what most physicians get wrong about niching. You think you're deciding who to turn away. You're not. You're deciding who can recognize themselves in what you say.
A patient with a problem is not shopping for a competent generalist. She's looking for someone who clearly understands her specific situation. When your message is broad enough to include everybody, it lands on nobody in particular, and she keeps scrolling. When it names her problem out loud, she stops.
And a niche isn't just a demographic. "Women over 40" isn't a niche, it's a census bracket. What you actually want is the psychographic layer underneath — what she values, what her day looks like, what she's already tried, what she's afraid of, what she wants her life to feel like in six months. That's the thing you can speak to.
Notice what didn't happen to the second dermatologist: she didn't stop seeing other patients. She got known for one thing, and the rest of the practice came along behind it. That's how this actually works.
How to find yours
Don't overthink it. Look at three lists and find the overlap.
Who you already see and enjoy. Go through the last three months. Which patients did you actually look forward to? Which visits ended with you feeling like a doctor instead of a data-entry clerk? There's usually a pattern in there you've never said out loud.
What you're unusually good at. Not what you're credentialed in — what colleagues send you. What you can do in a fifteen-minute visit that takes someone else forty. Your expertise is often invisible to you because it feels easy.
What people will actually pay for. The unromantic one. Skip it and you end up with a beautiful niche and an empty bank account.
Where those three overlap is where you start. Usually there are two or three candidates. Pick one.
Start narrow without burning the boat
I'll be honest with you: the first two years of my clinic were rough. Genuinely rough. Part of that was that I was trying to be everything to everyone, and my marketing said so, and nobody could tell what I was for.
But nothing about this requires you to blow up your existing practice on a Tuesday. You can test a niche while everything else keeps running.
Pick your candidate. Spend ninety days building one clear offer for that person — one page on your site, one talk you give, one email you send to the patients who already fit. Track what happens. Are those patients showing up? Are they staying? Are they sending friends? Are you enjoying it?
Ninety days won't make you famous. It'll tell you whether the door opens when you knock.
Give it long enough to actually work
The mistake I see most isn't the wrong niche. People pick one, mention it twice, hear nothing back, and go quietly generic again by month four.
Positioning is slow. You get known for something by saying the same thing, consistently, long past the point where you're bored of hearing yourself say it. The dermatologist above didn't become "the adult acne person" because she announced it once. She's been saying it for years — on her site, in her talks, to every referring doc she meets — and now the city says it for her.
That's the whole game. You keep repeating it until other people start repeating it.
So pick the thing. Say it clearly. Say it again next month. And stop trying to be the doctor for everybody. It's the most crowded, least profitable position in medicine.
