Patient’s Testimonials

When I first came to the center I knew nothing about functional medicine. I had an acute itchiness very excruciating for about 1 year and none of the treatments (cortisone, antihistamines, xolair injections) had managed to eliminate it. At the moment the itchiness does not exist and I feel well in general.

Niki S. (April 2021)


In the summer of 2015 I developed the disease pemphigus, I suffered and my only salvation was to take large doses of cortisone and other immunosuppressants. I visited some doctors and experienced (professors) and their only suggestion was to increase cortisone in each outbreak of the disease. In the summer of 2018 I chose to visit Ms. Koini, who suggested a treatment with vitamins and supplements for the proper functioning of the body and told me that I would be fine. I did not believe her but I applied literally every treatment and every piece of her advice and since Christmas 2020 I have completely stopped cortisone and every chemical medicine and the disease has stopped appearing, I AM WELL! Ms. Koini, from what I understand, tried a lot, was interested and looked into it to bring this result. Thank you very much!
Antonios S. (April 2021)

From the first moment, I felt very comfortable with the politeness and the kind treatment I had from everyone. Mr. Tigkas in particular is very informative and I gained high hopes.

Ioannis G. (January 2021)


The treatment brought a noticeable improvement of the dermatological condition after about 10 months. I no longer have itching on my scalp (I no longer need to wash my hair every other day in the best case). The itching and swelling of the joints in the hands and feet (toes, palms, feet) no longer exist. These irritations also raised fevers up to 38 ° C. The plaques on the knees and elbows are gone. Now there are only redness on the upper lip and a few mild redness on the forehead. I thank doctor Koini and her associates in Iator.

Vassilis R. (January 2021)


I came to the clinic in September with kidney problems and histiocytosis, as well as with extra pounds. To date, in addition to the treatment I receive, I have lost weight and generally feel better. Also, all the staff of the clinic is very kind, trained and of course humane. I’m expecting the results of the treatment I follow.

Aristidis G. (December 2020)


My nutritionist Mrs. Ifigenia Grivea is excellent. She trains me on a balanced diet with a calmer approach that has given great results – especially at a time when a few months ago the number on my scale was not changing whatever I was trying. I am grateful to her from the bottom of my heart and I know that this is a relationship that I will keep for a long time as achieving the ideal weight and maintaining it is not a race of speed, but a way of life.

Nagia V. (October 2020)

Weight loss

My decision to start this treatment was made after a research I have personally done to understand firstly where the problem starts and to fight it from the root and then from various examples I have read over the years about this method for autoimmune and metabolic diseases that affect more and more of us today. Iator and Dr. Koini put me in a position to understand thoroughly how we can regulate our body through this method !! I have gone to several doctors without any results …My experience: In the beginning I was a little cautious not knowing (in practice) how all this will develop and how long it takes to give me the desired results, but over time I saw month by month my improvement !! That was something that made me start to really believe in this method that I have decided to follow. It is the combination of Proper Nutrition – Nutrition Supplements – Exercise !! I’m glad I trusted the Iator Clinic which really helped me get out of this situation. I feel lucky to have done these analyzes to see what really concerns me at the cellular level. I have not finished my treatment yet but from the 0% that I was before when I started the treatment, now I feel that I am at 80%.

Thank you!!

Ioannis P. (September 2020)

First visit with Hashimoto’s treatment, with very extensive psoriasis and gyroid alopecia also very extensive. Three years after Hashimoto has been balanced, psoriasis does not exist and has not bothered me over the years. Gyroid alopecia has stopped. Hair has come out again, there are still gaps but light and weak hair growth. I have removed the hair piece this time. My hair needs strengthening. Outside, I generally  feel swimmingly in all respects.

Nikolaos P. (January 2020)


Within six months of receiving the treatment, both my physical and mental mood improved significantly. The feeling of fatigue and bad psychology was also reduced. I hope that in the coming months the result will be maintained because the truth is that the cost of both examinations and treatment is quite high.

Irini K. (December 2019)


Completely satisfied with the approach and the way it works, I appreciate the fact that when something does not work with my treatment, alternatives are suggested. And so I gradually move towards the goal of weight loss.

Very professional treatment, especially in the matter of keeping the appointment (no setups etc). The treatment so far has been particularly effective to the point where I wonder if it is my idea or reality. Everything I asked for, ie sleep, calm, energy, mood improved very quickly. I look forward to seeing how it’ll be in the future.

Hypothyroidism / Depression / Chronic Fatigue Syndrome

From the first days of the first month of treatment, the gas and bloating after meals (main and snack) and especially after dinner were greatly reduced. I have already lost 4 kilos of weight without having any feeling of hunger, as I had with various diets that I did from time to time. Swelling in lymph nodes and other areas, as well as muscle and joint pain, was significantly reduced. I do not swell and do not retain fluids from the heat, nor do I feel my feet heavy. I feel more energetic and cheerful, and this feeling of well-being continues after the main meals, while in the past it used to decrease sharply.

Theodora N. (September 2019)

With the treatment after the first week I started to feel less tired, more appetite for activities outside the house (walking). I noticed that the severe headaches subsided, while I had them every 2 days, now in a period of 1 month I noticed only 2! The skin rash (red cheeks and nose) due to the lupus subsided a bit and is covered with cosmetics, so I feel more comfortable. Certainly my night sleep is better, without cramps and discomfort (eg heartburn) and I do not feel sleepy like the previous days.

Chara K. (July 2019)

Systemic lupus erythematosus

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.(October 2018)

Functional Medicine

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. (October 2018)

Functional Medicine

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.(October 2018)

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.

Giannis S.(September 2018)


Functional Medicine

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.

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. (August 2018)


Functional Medicine

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.(August 2018)


Functional Medicine

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.

Μigraine - headaches

Functional Medicine

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.(June 2018)


Functional Medicine

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.(June 2018)

Systemic Lupus Erythematosus

Functional Medicine

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.(May 2018)


Functional Medicine

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.(May 2018)


Functional Medicine

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.
