Good day! During this treatment, I was only twice in this medical center, both times in the laboratory for blood donation, I waited 1 hour for the first time, 30 minutes for the second time, despite the fact that there was no visitor except me. All other actions, including the consultation of the doctor, were not in this clinic, so it is difficult for me, based on the foregoing, to make a different assessment. Also about the doctor. I was given the wrong doctor who was originally declared. I do not know anything about the current attending physician, please provide the data whenever possible. The doctor's conclusion, by the way, was also not carried out on Ichilov’s form — on a regular sheet and contains not the appointments that were made as a result, the doctor’s explanation of the side effects of the drugs (but I was going there, because your specialist said medicine without side effects and this was the key for me), appointed in the end and containing quite strong side effects.

I am very satisfied with the outcome of the surgery; it is the best possible result that could have been achieved
What I appreciated the most was the support from coordinator Sergey and the clinic's representative, Denis. They assisted me with different questions and situations. They created an easy, pleasant, and friendly atmosphere. After the surgery, Denis helped purchase the necessary medications and always organized my transport from the clinic to home. He also assisted with currency exchange locations.
I am very satisfied with the outcome of the surgery; it is the best possible result that could have been achieved.
Heartfelt thanks to the Bookimed team!

We are very grateful for the small chance that these doctors gave us
We received a detailed consultation with Dr. Pelles Sharon and her assistant Denis. They explained everything, gave me a treatment plan, and the doctor was very attentive to details. We are very grateful for the small chance that these doctors gave us. I would also like to note the work of the coordinator, Yulia. A very sensitive, empathetic specialist, she was able to organize everything quickly. Thanks a lot!

Accompanying Denis has extensive experience and a very interesting interlocutor. You have a good team! Well done!
