How This Physician Entrepreneur Built a Cash-Pay Practice With a 350-Person Waitlist

Physician entrepreneurs

From “I Don’t Know the First Thing About Business” to Fully Booked Until February

Two years ago, she was still employed.
Still wondering, “Could I really do this?”
Still battling imposter syndrome so loud it could shake the walls.

And now?

She runs her own cash-pay private practice,
charges like a lawyer,
and has a 350-person waitlist—without spending a dime on marketing.

Let’s talk about Dr. Rachel Rubin’s journey.
Because it’s not just inspiring—it’s instructive.

And if you’ve ever felt like you weren’t cut out for business?
This story is especially for you.


“I Don’t Know the First Thing About Business”

Dr. Rubin kept saying this out loud—even as she built her dream.

She said:

“I joke… even now I don’t know the first thing about business. And here I am—running my own.”

Let’s pause there.

Most physician entrepreneurs believe they need an MBA to start.
But what you actually need?

  • Courage to begin
  • A community to catch you
  • And a willingness to learn as you go

If you wait until you’re “ready”—you’ll never start.

Dr. Rubin did it scared. And it worked.


1. Imposter Syndrome Doesn’t Mean You’re Not Ready

Dr. Rubin is a sexual medicine urologist.
Not exactly a field full of cheerleaders.

“Urology is a pissing contest—literally. Everyone’s trying to push each other down.”

That environment made her question everything.
She said she used to take propranolol before speaking to five residents.
And still—she showed up.

“You do it scared. I was scared when I started med school. Scared in residency. Scared with my first patient. So how hard could QuickBooks be?”

That’s the mindset shift.

If you’ve done hard things before
You can do this too.

2. Community Is the Ultimate Business Accelerator

There’s a reason her entire business changed inside a physician entrepreneur community.

She said:

“The community made me believe in myself in ways that medicine never did.”

This wasn’t fluff. This was survival.

When she had a meltdown, she didn’t spiral—
She leaned on them.

“Wednesday, I had a temper tantrum. I said, ‘I can’t do this.’ And my EBS friends lifted me up.”

Entrepreneurship will test your emotions.
Having people in your corner who get it? Game-changer.


3. Follow the Framework (Even When You Hate It)

Dr. Rubin didn’t want to make videos.
Didn’t want to be on YouTube.
Didn’t want to show her face.

But when she did?

“Every time I make a video, I get 1,000 new Instagram followers.
When I just post a graphic? Crickets.”

She went from 5,000 followers to nearly 20,000,
got quoted in the Daily Telegraph,
was invited on her hero’s podcast

And none of it happened by chance.

It happened because she followed the system—
even when it felt awkward.


4. Charge What You’re Worth—Without Apology

This one took time. And coaching.

“I’m learning to value my worth. I charge like a lawyer. You want my expertise—you’re gonna pay for it. I’m not apologizing anymore.”

Let that sink in.

Physician entrepreneurs often feel guilty for charging.
But the work you do saves lives, restores dignity, and changes families.

That’s not cheap work.
It’s not casual work.
It’s valuable.

Own your value—and price accordingly.


5. She Never Ran Ads. Not One.

No Google Ads.
No Facebook Ads.
No marketing agency.

And yet…

“When I opened, I had a waiting list of 350 people.
If you call my office today, my next new patient appointment is in February.”

You want to know how she did it?

  • Showed up consistently online
  • Shared her passion loudly and often
  • Educated the public relentlessly
  • Built trust in advance

“It’s not about followers. It’s about impact. I want you to learn the field, love it like I do, and teach others.”

When you care that much, people line up.


6. Let the Math Math

Business doesn’t work on vibes.

“I’m learning to math. I’m learning to make the math math. The business has to be profitable. And I’m learning to run it like one.”

She didn’t take out loans.
She runs a 100% cash-pay model.
She built everything organically—with clarity and intention.

She’s frugal (she joked, “I don’t even pay for gum!”)
But she invested in her education. In herself. In the right room.

“I never invested in myself before. Except for med school. This is the first time. And I think of it like a marketing budget.”

And it worked.

What You Can Learn from Dr. Rubin’s Story

Here’s your prescription, doc:

1. Do it scared

No one feels “ready.” Start anyway.

2. Find your people

The right community will carry you when you forget who you are.

3. Share your passion out loud

If you’re not talking about what you do, who will?

4. Make video content

You hate it. It works. Do it.

5. Charge your worth

Stop apologizing for expertise you worked decades for.

Let the business be a business

Math it. Monitor it. Move it forward.


Final Word:

Dr. Rubin ended with this:

“I just want you to know how regular I am. I’m flawed. I used to pop beta blockers before speaking. And now I’m quoted internationally, running my dream business.”

That’s the magic of physician entrepreneurs.

It’s not about perfection.
It’s about purpose, people, and persistence.

You can do this.
And just like her, you don’t need permission
You need a plan.
