"The result of the surgery is excellent
The clinic is very large, the conditions in the room were very good, there was even a folding chair for an attendant. Food was brought for both of us. The doctor aroused confidence from the very first consultation. But also a whole team was engaged in my operation and they are all great professionals. Nurses have also always been very helpful.

"I recommend to everyone, wizards work here - professionals in their field!"Categorized statements: About the doctor: "Easy to communicate, concise, it is immediately clear that the highest level specialist, after the examination, identified the problem and showed it on the MRI scan and explained what was to come
LIV Hospital services are very much in line with and in no way inferior to the world level, believe me, because due to health problems of my family, we had to see clinics in the USA, China, South Korea, Israel. From the very first call I felt great care for me as a loved one. Many thanks to Sabina, Nigina - coordinators / translators, they did a great job, we could contact them at any time of the day and they supported the patient with all their hearts. Please note that everything here is based on Turkish, only doctors can communicate in English. It can be seen how much Turkey has advanced and is self-sufficient. I am grateful to fate that I met the professor - neurosurgeon Chagatay Ozturk. Easy to communicate, concise, it is immediately clear that the highest level specialist, after the examination, identified the problem and showed it on the MRI scan and explained what was to come. An operation was performed to remove the hernia on L5-S1 and a titanium disc was installed. The atmosphere of the team was very favorable and cozy, there was a high level of coherence and discipline. The concern was such that I did not feel any pain or heaviness, although they say that the operation was not an easy one. On the second day after the operation, I already walked and on the sixth day I was already discharged. Finally I got rid of pain and sleepless nights over the years! I recommend to everyone, wizards work here - professionals in their field! Best regards, Gaziz Kissym Kazakhstan

The Liv Hospital Clinic confused my diagnosis. Within two hours, I thought I had cancer.  I immediately wrote to them, the answer came in two and a half hours, as they had no time to double-check. During all this time, my family and I went crazy with horror. Now they wrote to me that the translators were wrong. But pituitary adenoma is spelled the same in all languages. A malignant formation of the parotid gland is a completely different diagnosis.
