How Lauren Barker did it: The Doctor Who Left Medicine to Build a Clinic Network
Lauren Barker was a certified medical doctor in New Zealand — six years of university, three years practising across mental health and emergency medicine settings. There was no dramatic exit moment. She'd known from early in university that she wanted to work outside the hospital, in an environment where you could say "I wanna try that and see if it works" — the opposite of a system designed, rightly, to minimize risk and run on protocol.
The path out ran through 18 months at a consulting firm and three years at health startups and scale-ups before a meeting with Good Mind Therapeutics. What she found there was a slide titled something like "novel treatments" and a 4-by-4 of maybes — maybe a platform, maybe clinics. A group of investors who saw an opportunity with novel treatments but didn't know what that opportunity was. She said yes anyway, because she'd been reading about the lobbying for ketamine treatment, it wasn't big in Australia, and being a first mover looked like a really interesting business to build.
The company had been set up around psilocybin and potentially MDMA therapy — Australia being the only country in the western world with that legalised therapy pathway. Lauren pushed back: the model there is incredibly governance-heavy, the research is still early and inconclusive, and you can't build a business on what the TGA might do in the next five years. Good Mind pivoted into what was accessible now — ketamine for treatment-resistant depression. Around the same time, the original co-founder left. Angel funding in the bank, broken model, and Lauren suddenly responsible for other people's jobs. She did a lot of crying. Then she picked up Google Ads and backend website design — "you can learn that shit on YouTube" — and kept building.
This episode is also the clearest explanation of ketamine-assisted therapy you'll hear from a founder. Treatment-resistant depression isn't a niche illness — roughly 1 in 5 Australians will have depression in their life, tablet antidepressants work for about half of them, and by the third failed tablet you're talking about millions of people the system has stopped helping. Ketamine hits different neurotransmitters, works within about 48 hours for most people, and stimulates the growth of new pathways in the brain. About 70% of patients will have their depression treated or cured.
Today Good Mind runs a hybrid of telehealth and in-person care across five clinic sites, at break even, with the "if we build it, will they come" question finally answered — they came. The next problem: scaling from five to 50 clinics without breaking a really nice customer experience, keeping the team at four or five people while delivering thousands of standardized, pleasant instances of patient care.
What you'll hear
- Leaving a decade of medicine — no single moment, just a system built to minimize risk with no scope for creativity
- Saying yes to a chaotic slide deck — the 4-by-4 of "maybe a platform, maybe clinics" and the first-mover bet on ketamine in Australia
- The pivot away from psilocybin and MDMA — why you can't build a business on what the TGA might do in five years
- Treatment-resistant depression, demystified — 1 in 5 Australians will have depression, tablets work for about half, and the label is a hangover from a system before ECT and TMS
- How ketamine actually works — a direct antidepressant effect within about 48 hours, plus a burst of new pathway growth in the brain
- What patients actually pay — from $800–$1,000 a dose to three to five thousand dollars out of pocket over a full course after the PBS listing
- Rebuilding solo after the co-founder left — the crying, the imposter syndrome, and picking up Google Ads from scratch
- LinkedIn versus reality — Lauren's lowest day, and why she stopped being on LinkedIn to stay in her own lane

Quotes from this episode
I have no idea — like I've got a hypothesis, but until we've built it we won't know. And there were a lot of dark nights of the soul.
— Lauren Barker, on the six to nine months before any demand signal (03:46) It's not that I don't like this idea, it's that you can't bat on what the TGA is gonna maybe do in the next five years. You can't build a business on an idea that maybe something will change.
— Lauren Barker, on pivoting away from psilocybin and MDMA (05:14) If people can sell peptides, surely I can make a business of something that actually works.
— Lauren Barker, on getting past imposter syndrome (12:22) I did not know what a Google Ads dashboard looked like. You can learn that shit on YouTube — like, you can learn everything.
— Lauren Barker, on filling her skill gaps solo (12:31) You see Instagram versus reality — and I think there's this thing which is like LinkedIn versus reality.
— Lauren Barker, on her lowest day as a founder (16:15)
Themes Lauren returns to
- Regulatory realism — build on what's accessible today, not on what the TGA might legalise in five years
- Skills are learnable, not identity — Google Ads, performance marketing, backend website design, all picked up in six months ("you can learn that shit on YouTube")
- The comparison trap — LinkedIn versus reality, and choosing to stay in your own lane for your mental health
- Evidence over hype — the hill she'll die on is people being sold things that do not work
- Lean scale — four or five people running thousands of standardized, pleasant instances of patient care
- Seasons of building — summer creativity, dark nights of the soul, then the signal that what you're doing is right
