“I sought out Dr Diamandis’ help based on a prior positive experience I had. I initially sought advice to better understand some perimenopausal blood results, as her explanations were clear and logical I felt an immediate sense of evidence based and trusted guidance. As I was concerned about my mother’s blood results, particularly in the context of her age and current change in her blood tests I went for a second opinion to Dr Diamandis. What stood out was the ability to receive a clear, balanced second opinion that put everything into perspective. The explanations were thorough yet easy to understand, helping me distinguish between what was expected and what might need monitoring for my mother and we discussed current guidelines and why further tests were needed. Communication was excellent throughout extremely responsive, patient, and never rushed, which made it much easier to ask questions and fully understand the situation. We felt listened to and taken seriously at every stage. My mother came away feeling much more informed and reassured, with a clearer understanding. I am very grateful for the clarity, reassurance, and trust this has given me as it made a significant difference to us both as patients.”

“I can’t recommend Lafina highly enough. She has an incredible ability to combine medical knowledge with a holistic approach, helping me truly understand what’s going on beneath the surface rather than just treating symptoms. She’s so easy to talk to, genuinely listens, and makes you feel completely seen and understood. Working with her has helped me get to the root causes of things I’ve struggled with for years — and I finally feel like everything makes sense.”

“I started Deia Health because patients deserve more than a rushed appointment.”

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

30-90 min
10-15 min

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.
