Good afternoon! I would like to say that you have a wonderful Center. Great attitude from the dressing room to the operating room. The first time we came to your center in June 2020, my father's hemoglobin was falling, and thanks to the professionalism of the endoscopist Pavlov I. A., we found a rare cause of blood loss and were operated on by him. In January 2021, I was diagnosed with chronic calculous cholecystitis and scheduled for elective surgery. I was operated on by a wonderful surgeon, I. V. Kazakov. I would like to say a huge THANK YOU to all the staff of the MCSC. Loginova! I wish you health and prosperity!
