Dr Lafina Diamandis is caring and supportive with her patients. She provides clear explanations for conditions like perimenopause and digestion, giving personalised plans. Patients value her thorough, proactive approach; she listens well and gives effective, holistic solutions. Her expertise aids general health assessments, hormone imbalances, and men's health.
Dr Lafina saw me today for my ongoing and chronic disease, after I’ve gone into a new and prolonged flare up and our preciously agreed toolkit of medications, diet and lifestyle choices haven’t been enough to calm it down. She went into so much detail and invested time to research any additional therapies available to help me. I always feel so very well head and taken care of.
Dr Lafina, has helped me so much with my health. I was going through peri menopause and she was able to reassure me and provide a real health plan that transformed my health. She is also super kind and understanding. She listened to me and took time to be so thorough. I was so grateful!
Dr Lafina is the best - she’s caring, genuinely interested in me as a person and the big picture rather than individual results. It’s always a pleasure to see her - even for someone who can find medical interactions anxiety inducing.
Very helpful and caring doctor. I missed my appointment due to an accident. The team was very helpful to rebook me for another appointment and I was not charged for the appointment even when I did want to pay. Lafina is a valuable asset to society and to all our lives because of her medical knowledge and caring attitude to others.
Firstly, I would like to say that writing this review was very hard for me, because it brings a few tears to my eyes. I described Dr Lafina as irreplaceable valuable asset to society and to all our lives, because Lafina has made a profound positive impact through her work and kindness. Lafina has a special energy in her that innovates and motivates people, turning struggles into a message that helps others thrive in life. This special, irreplaceable energy that feeds the soul is priceless. It nurtures our well-being and cannot be bought or replaced. Lafina founded DEIA Health just for us, so we can all enjoy a good health and access support. This is the only medicine and support I can't get from anywhere else in the world, it is priceless. I just wish my health was better and I had the ability to seek more help and support from Dr Lafina.
Dr Lafina is a thoughtful and knowledgeable doctor who supported me through challenging perimenopause symptoms and digestive issues. She brought in the right specialists to properly diagnose and address my concerns, and I’m now well on my path to healing.
Couldn't be happier with my recent visit. Lafina's genuine care alongside expertise is second to none and that combination at the level she provides it is an experience/service you'll struggle find anywhere else. She's super proactive and what's great is how after every appointment we go away with a clear plan of action which leads to overall improvements next time check up.
Lafina was great, happy to explain things in human terms and offered some useful advice
Lafina is not only an experienced and excellent doctor, she practices whole person medicine - prevention and cure in a truly holistic way. And a warm, empathic clinician to boot

Obstetrician & GynaecologistDr Diamandis has a very calming manner and immediately makes her patients feel at ease. She takes a broad view of her patients medical problems and assesses them at all angles, including non-prescription based. We share a number of patients and they all speak very highly of her. I have no hesitation in recommending her.
