The practice
Founded to hold one hundred histories properly.
Lucien Health is a physician-led private practice, established in London in 2014 and now working from four cities. We coordinate and manage medical care with regulated physicians and accredited facilities for a panel that is deliberately small.
01 — Origin
Nobody was reading it all together.
The practice began with an audit rather than an idea. In 2013 a London physician sat down with the paperwork of a dozen long-standing private patients and found the same pattern in every file: records held in three or four countries, scans nobody had compared, bloodwork repeated within the year because the earlier result could not be located, and a specialist letter that had never reached the family doctor.
None of it was bad medicine. Each consultation had been competent on its own terms. What was missing was the thing no single clinician had been asked to do: hold the whole picture, over years, and notice what moved.
Lucien Health opened in 2014 with four households and one principle: a named physician, a single record, and a cap on how many families that physician could reasonably carry. The number settled at one hundred, which is roughly the point at which a doctor stops recognising a name and starts looking it up.
Zurich followed in 2017, New York in 2019 and Singapore in 2022 — not as expansion, but because members were already living across those time zones and wanted the same record and the same physician wherever they woke up. The cap did not move.
“We were not short of medicine. We were short of someone whose job it was to read all of it.”

02 — How we work
Six commitments we hold to.
These are not aspirations. They are the operating rules of the practice, and they are the reason the panel is the size it is.
One physician, named.
Every member has a single doctor whose name sits at the top of the record. They see you at each assessment, they read your results before you do, and they are reachable without a switchboard between you.
Every test must change a decision.
Before anything is ordered we ask what we would do differently depending on the result. If the honest answer is nothing, we leave it out and tell you why.
The panel stays capped.
One hundred households, reviewed quarterly. The cap is the practice. It is what allows a physician to hold a family’s history in mind rather than look it up.
Results are read together.
Imaging, bloodwork, cardiac testing and genomics are reviewed in one sitting, against your own prior years. Signal usually lives in the relationship between findings, not in any single number.
We write to you in plain language.
Findings are set out in a written summary you can read without translation, with the uncertainty stated where it exists. The full clinical detail is there too, underneath, for whoever needs it.
Your record is portable, and it is yours.
One encrypted record, exportable in full on request, released to a third party only on your written instruction. If you ever leave the practice, the record leaves with you.
03 — The people
A small team, and you meet all of it.
We describe roles rather than parade credentials. You are introduced by name to the people who will hold your record before you are asked to commit to anything.
Founding physician
Trained in internal medicine in London and practised for nine years across NHS and private settings before founding the practice in 2014. Still holds a small personal list and reads at every assessment week.
Medical director
Trained in internal medicine and spent eleven years in NHS acute care before moving to preventive practice. Sets the clinical standard, chairs the weekly findings review and signs off every protocol change.
Head of diagnostics
A subspecialist radiologist by background. Selects and audits the imaging and laboratory partners we use, and coordinates the second read that every scan receives before it reaches you.
Care managers
Four of them, one to roughly twenty households. They book, chase, collect and file: appointments, prior records, referrals, insurance correspondence and the travel logistics around a two-day assessment.
Specialist network
Named consultants in cardiology, oncology, neurology, endocrinology and orthopaedics in each of our four cities. Every one of them has been used by the practice before we send you.
04 — In numbers
The whole of the practice, on one page.
Seventy-four of one hundred places are held. The remaining twenty-six are offered as places open and reviewed each quarter, and we would rather hold a place open than fill it badly. When the panel is full, enquiries are kept on a waiting list and answered in order.

If the way we work suits you, the rest is a conversation.
Membership terms, fees and what a year with the practice actually involves are set out in full. The first conversation is with a physician, lasts about forty-five minutes, and costs nothing.
