Autoimmune Diseases

αυτοάνοσα νοσήματα

Constant deviations and contradictory interventions on our cellular processes at the biochemical level, which may be accumulating for years, underlie and at some point they manifest, in the form of a Disease. The deviation from natural lifestyle and nutrition as well as “toxic load” burden, are the main routes promoting Autoimmune Diseases.

Medicine at the Molecular Level

“We see deep inside the cell”


The mechanisms that regulate the aging of our cells are at the ends of chromosomes. Their name, telomeres, is derived from the Greek nouns end


Genova Laboratories

Innovative diagnostic laboratories from the U.K., U.S.A., Austria and Greece perform genetic and molecular exams at the cellular level.


Biomimetic Hormones

Biomimetic (Bioidentical) hormones are produced in the laboratory and they have the same molecular structure as our own hormones. The hormones produced by our organism. To the contrary, synthetic-chemical hormones are deliberately different.


Human Genome

The mapping of the Sequence of three billion nucleotide bases, which form human chromosomes, provide the answers to “Hereditary Diseases”.


Evidence Based Medicine

Specialized exams at the Molecular and Genetic level, as well as the ability to translate the genome, allow us “to see” and provide a comprehensive treatment for the Disease, not the symptom.

Then we can get 25000 IUS (international units)”. This is what Ron Rothenberg, M.D., specialized physician in anti-aging, said during the annual congress of […]


Opinions and Experiences of our Patients

  • Andriana G. Andriana G.
    I was impressed by the detailed assessment of my medical history, as well as by her interest in my case and the transmission of her scientific knowledge. But, above all, what impressed me was that through specific exams and the proper reading of my exam results, something that neither internal medicine doctors nor neurologists had done till now, she suggested a treatment regimen with Biomimetic hormones and the appropriate vitamins, and my problem was solved within 6 months. I really thank her for this.
  • Fay S. Fay S.
    Dr. Koini is super!
    She is detail oriented and very specific explaining everything and answering all questions without hesitation or rushing her patients. She helped me with my migraines from which I have suffered a lot. I used to take 2 anti-inflammatory pills per day and now I am happy to stop all of these.
    I am thankful to her.
  • Katerina Ν. Katerina Ν.
    Blood pressure was a chronic problem for me, and I wanted to try something different from traditional Antihypertensives that were prescribing to me. I wasn’t happy neither with the result nor with the side effects.

    So, I visited Dr. Koini at her practice, and through the Functional Medicine system my condition was managed differently.

    And I would definitely recommend it, as it was not only different, but also substantial.

    Nice reception area, and very polite administrative staff.

    Dr Tigkas explains in detail the causes that led to the development of your problem, as well as the course of your treatment. You may have to stay even for one hour in his office so that to explain his Scientific knowledge and make sure that you understand exactly what you have to do in order to be cured. Ms Koini is always there happy to welcome you, she is accurate on which treatment to suggest, and gives always the right advice!

    They are both wonderful people, really focusing on your problem and always full of optimism. It is also remarkable that they believe in natural treatment methods and never prescribe chemical formulations.

    And, above all, I managed to overcome the symptoms of the climacteric and Menopause, and I feel happy again as a woman, without being nervous, with no mood swings, without feeling tired, in the mood for sex.
