Шухрат • Consultation with a neurosurgeon

Verified review.
When asked what I specifically liked, I honestly answered — everything
The initial conversation with the neurosurgeon immediately determined my choice. I received comprehensive answers to all my prepared questions, and I had no doubts about the next steps. This approach to the patient was characteristic of the entire process. When asked what I specifically liked, I honestly answered — everything. From the initial trip organization through Bookimed to the staff's work at the clinic itself. It's hard to single out just one thing. The surgeon and the entire team worked very cohesively, and I didn't encounter any shortcomings. I am currently in the early stages of recovery. For those seeking precision and professionalism, I can say that the organization was at the proper level.

My recommendations to friends, acquaintances only this Clinic! The prices are reasonable
Good day! I would like to share my impressions of being in the clinic. Thanks to the coordinators, the staff of the international clinic center, all wishes were taken into account. Special thanks to the attending physician, the procedure was perfect, the staff is very attentive, courteous. They are located in a 5-bed room, but at the same time there is no discomfort, food can be chosen taking into account personal taste preferences (Korean, European cuisine) and at the same time satisfying and varied. I can say one thing, there is no limit to my gratitude, my recommendations to friends, acquaintances only this Clinic! The prices are reasonable.
