The doctor who will hold your whole picture.

or simply having a GP who has time to listen. Dr Lafina supports general health,
women's health and ongoing needs.
The honest comparison
A one-off appointment or GP care that continues to support you
The difference is not luxury. It is time, continuity and a plan that someone stays responsible for.
DEIA GP
STANDARD GP
Time with your doctor
Longer appointments mean symptoms are explored in full rather than rushed through a ten-minute window.
Same doctor at every visit
Continuity matters. You see Dr Lafina each time, so nothing is lost between appointments.
A curated multidisciplinary team around you
GP-led care, joined by clinical psychology, gut health and functional medicine nutrition, somatic therapy, breathwork and movement. The team meets monthly to discuss shared patients.
Full history and timeline reviewed
Your story is pieced together across lifestyle, family history, past results and current symptoms.
Testing chosen around you, not a fixed panel
Blood tests and screening are selected for your risks, not sold as a one-size-fits-all package.
Results explained face to face
Every result is discussed in person so you understand what it means and what to do next.
Written plan you keep and can share
You leave with a clear, shareable plan rather than a brief note or prescription alone.
Hormone, thyroid and metabolic work-up
Energy, mood, weight, sleep and cycle issues are investigated with the right hormone and metabolic tests.
Referrals coordinated by your own GP
If you need a specialist, the referral is arranged and followed up by the doctor who knows you.
Reviews built into the year ahead
Care does not end at the appointment. Follow-ups are planned to keep you on track.
Direct line between appointments
You have a direct route to the clinic for questions that arise after your visit.
Before you book
Questions patients usually ask
Still unsure? Speak to the clinic team and they will point you to the right appointment before you commit.
No. You can book directly with the clinic. If you already have letters, scans or blood results, bring them — Dr Lafina will read them before your appointment.
A full history and timeline, examination where relevant, discussion of what may be driving your symptoms, any targeted testing that will change the plan, and a written plan in plain language.
Yes. Continuity is the point. Dr Lafina holds your case, and coordinates any specialist referrals herself.
Yes. Advanced screening is chosen around your family history and risk profile, and every result is explained face to face rather than emailed as a PDF.
Some appointments are eligible depending on your policy. Please check with your insurer before you book.
