I want to express my gratitude to the endoscopist Kirova Marina Vladimirovna and the nurse Savina Maria Alexandrovna! A wonderful doctor and nurse made a highly qualified research. Thanks to their experience, the procedure was very fast, painless and successful. I do not have enough words of gratitude for such a research, that before I did a colonoscopy several times with other doctors and it was always very painful and could not even undergo a full examination (I stopped the procedure), and this time I was very surprised how good everything went. Marina Vladimirovna, you are an impeccable specialist in your field, sensitive, attentive, caring and very competent! I am glad that it was you who did my gastroscopy and colonoscopy! Nurse Savina M.A., thank you for the quality help to the doctor and me during the procedure and the necessary and timely words of support, without you I would not have tuned in and relaxed! I would like to thank you for your work and professionalism!
