Until now I had struggled too much to lose weight. I was visiting one dietician after the other, as well as many Weight loss Institutes. I had tried everything, with no result. Until someone told me to visit Ms Koini, and I went to her medical practice. She managed my condition differently through the Functional Medicine System, and she achieved what I was trying to achieve for years. Excellent attitude, both as a Scientist and as a person.

My migraines were totally cured by Dr. Koini and I am very happy for this. I totally recommend her.

Foster S.

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.

Katerina N.

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.

Fay S.

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.

Eva Κ.

I was diagnosed with early onset menopause (since I was 33 ) and now after so many failed trials with other doctors, they managed to have my menstrual circle again.

I am thankful to them.

Olga D.

I was diagnosed with a fibroid cyst on my uterus, which was actually pretty big (10 cm). I was also experiencing hormonal changes due to this fibroid cyst, and it was basically altering my mood and feelings. We were nervous about it, and together, Dr. Tigkas, Dr. Koini, and I decided to try a “new knowledge” approach to combat it. They recommended I begin a therapy with bio meds, so I could avoid surgery and begin to feel better. The progress would take some time as my body needed to adjust to these meds, but I was patient and willing to try it.

After a couple of months, I was indeed feeling better, but we noticed an alteration in my blood work regarding a hormone level. We ran some tests and discovered a cyst on my right ovary, which was close to 51 cm big! The doctors became even more concerned, but they acted right away. We upgraded the dosage of the bio meds, and being the patient person I am and feeling confident in their care, I went on my summer vacation! Of course, we were in contact every week, and I was being monitored even though I was away. During the summer, I upgraded and downgraded the meds as needed, and by doing so, I induced my menstrual cycle a little frequently. Everything was well regardless.

Upon returning after my vacation, I went to Dr. Tigkas and Dr. Koini for my post check-ups. Well, I was in for a happy surprise as we discovered the cyst on my right ovary was gone, and my fibroid cyst had actually shrunk to about 6 cm in size! Boy was I elated! I am continuing my bio meds and taking care of myself, and for now, surgery is nowhere in the near future.

Overall, my whole experience at NK Clinic is an amazing one. I never had the love, care, and concern of two professional doctors as these two. Both, Dr. Tigkas and Dr. Koini, embraced me and really took a humane and professional approach to help me combat my medical issues. They taught me and showed me what “new knowledge” to medicine is, and I am the live example that this really works! I completely trust them, and they never made me feel that my only option was surgery. They were with me every step of the way, and I am now stronger and healthier than before. I am definitely in this for the long haul, and I am so much more at ease knowing that these two doctors are in my life taking genuine care of me.

I definitely recommend NK Clinic and the “New Knowledge” approach to medicine, and I am confident you, too, will see the difference.

Thank you

Stavroula S.

I visited Ms Koini for a significant problem I had with morning fatigue. 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.

Andriana G.

For many months and years I was suffering from bronchial asthma, using typical treatments prescribed Pulmonologists and General Practitioners. Finally, searching led me to Ms Koini, who solved my problem through the Functional Medicine approach. It was impressive… within a year my asthma attacks were reduced, as well as my allergies. And all this through natural methods.

Eleftherios P.

I scheduled my visit at Ms Koini’s Functional Medicine clinic following a recommendation for erectile dysfunction reasons. After a specific hormonal check-up and detailed investigation of my medical history, the doctor suggested taking vitamins and Biomimetic hormones, and my problem was finally solved soon after.

Giannis S.

I visited Ms Koini due to my chronic fatigue. I was dead on my feet. I was all the time in bed, couldn’t get up. I even reached the levels of depression. No doctor, General Practitioner, Neurologist, Psychiatrist, had helped me. After extensive internet research, I discovered Ms. Koini, through the website of the American Academy of Anti-ageing, and thus I visited her.

The system she followed to finally solve my problem (Chronic Fatigue Syndrome), helped me within 6 months to stand on my feet. Within 1 year, I was cheerful, energetic, another person. I am grateful to her. May God bless her.

Panagiotis Μ.

I visited Ms Koini for my sudden problems of hot flashes and mood swings. She diagnosed, after special exams and the detailed investigation of my personal history, Menopause, and with the help of Biomimetic hormones together with the appropriate vitamins, my problems disappeared after a little while. I am happy again.

Νana Τ.

I was diagnosed with early onset menopause (since I was 33 ) and now after so many failed trials with other doctors, he managed to have my menstrual circle again. I am thankful to him.

Amber D.

I visited Ms Koini as I had no sexual interest lately. The doctor examined me carefully, she asked my full medical history, and she suggested doing certain exams. Then she proposed treatment with Biomimetic hormones and with the right vitamins and elements she made, I am now in the mood again, so I saved my marriage. I am thankful to her.

Elina Κ.

I had a huge problem with cystic acne on my face, which made me suffer for years, and I had visited many Dermatologists, who only suggested treatments with pills and creams, as well as antibiotics and retinoids for 3 sessions. And they didn’t work at all. So she suggested having a hormonal test and then I followed the treatment of the Functional Medicine system. My problem was solved forever. I am really grateful to her, I hope she is always well.

Christos V.

I was suffering from my migraines for too long. Photophobia, vomiting and extreme headache, which was going away only with robust anti-inflammatory and antidepressants. I had visited many neurologists, and I had seen no result, until I found Koini and her system, which I followed. I had some special urine tests that were sent to the U.S. The results were ready after a while, but treatment was worth it, I was finally well. I thank her, I am deeply grateful to her.

Katerina A.

I want to thank the doctor and her system that finally gave me the social life I always wanted. I had a very serious problem with my intestines, gases and bloating, so I couldn’t participate in any social events, something that led me to depression, which further worsened the condition of my intestine. Doctors had diagnosed Irritable Bowel Syndrome but no treatment was working. Fortunately I trusted Ms Koini and I was saved. I followed the system of Functional medicine and after specific stool tests that were sent to America, she gave a treatment with elements and vitamins and then I was fine. I was saved!

Mary P.

My son is 7 years old, and since he was 4 years old, I was all the time concerned with his social behavior. After various psychosocial tests, the diagnosis is ADHD (attention deficit hyperactivity disorder) and mild autism. I have searched for many treatments that were suggested to me. I also tried Functional medicine, and I dare to say that it really helped in improving the attention deficit of my little one.

Ioannis A.


For a long time now I had a problem with my blood sugar. I used to have and I still have a sweet tooth. When I had the first symptoms, I visited the hospital, where it was the first time that Diabetes Mellitus was diagnosed. Then I visited a diabetologist, who prescribed pharmaceutical treatment with pills. Lately, after years of research, I found Ms. Koini’s system of Functional Medicine, and I just followed it intently; so my health was restored without any pills, just with vitamins, after six months of monitoring and treatment and many exams she asked me to do. I am really grateful to her.

Giouli S.

Many years had passed since the last time I woke up feeling just fine. I was always feeling tired, especially in the morning, and mentally depressed. I was feeling “heavy” in general. When other doctors had performed exams for these, they would always say I was healthy, and that I had to stop feeling anxiety. They suggested me to visit Ms Koini, who examined the levels of all my hormones, and diagnosed subclinical hypothyroidism. She treated me with biomimetic hormones, supplements and vitamins and now I am feeling very well. I get out of bed feeling in the mood for life, I feel fine throughout the day.

Panagiotis A.

What can I say for my Psoriasis that I have since I was young, when I had a car crash. It destroyed me emotionally and socially. My problem was serious, throughout my body, and it could not be treated, although I visited many dermatologists. I searched intensively and fortunately I found Ms. Koini. Then I followed strictly her program and I was finally treated. Of course my urine and saliva tests had to be sent to America, and I also had hormonal tests, she monitored me each month, and through the vitamins and the special diet she gave me, now I am well. My skin cleared and I am very happy.

Anastasios Th.

Years ago I was diagnosed with Lupus. I had a butterfly on my face. I got stressed, sad, and I visited many doctors, both in Greece and abroad, as well as many alternative medicine practitioners. In the end I visited Ms Koini, who did not promise to solve my problem, but she managed to treat it through the system of Functional Medicine, which I strictly followed. The butterfly disappeared gradually and my laboratory exams were improved. I also stopped receiving those robust drugs I used to. I am very happy with the system of Functional Medicine.

Andreas V.

Since I was a child I was diagnosed with atopic eczema. I was always itching and my skin was dry, leaving scars behind. Fortunately, after many unsuccessful treatments by different dermatologists, I found a different approach in Ms Koini’s medical practice and I got rid of my skin problem for good.

Marietta K.

From the age of 16 until now that I’m 21 years old I had one problem that really bothered me. Acne. Antibiotics, creams without antibiotics, creams with antibiotics, creams with acids, creams without acid, soaps and treatments that lasted for many months. Pills, contraceptives, retinoids and lamp treatments, as well as peelings in the doctor’s office. All improved my condition for a while, but the problem would not go away, it was just coming back. Then I started reading, until I reached to the source of my problem, Ms. Koini’s medical practice, who after specialized exams, careful monitoring, and treatment through the system of functional medicine, finally reached to the permanent elimination of my problem.

Tania Ch.

I am 50 years old and I was a manager in a large company for many years. Too much stress. Three years ago I couldn’t even get out of bed, or even my chair, I couldn’t do anything. I was staying in bed all day, feeling constantly depressed. Doctors could not diagnose anything. Then someone suggested me to visit Ms Koini and I found my good old self. Treatment lasted for long, but gradual improvement was evident from the 4 th month, and especially after 6 months. Special exams were necessary, which were sent to the US, a special system and nutrition, as well as biomimetic hormones and her own formulation of vitamins and other micro-molecules. Her system treated my Chronic Fatigue Syndrome, as she called it. Now I am fine, but I still follow her advice for a healthier and more successful life.
