I would like to express my great gratitude to the gastroenterologist of the consulting center Maria Sergeevna Morozova. A very attentive and correct doctor. Thanks to her professionalism, she promptly collected the necessary documents and was hospitalized for a check-up at the NPC department. It is very nice when a doctor is attentive, correct, patient and can advise and arrange documents so that the patient receives all the necessary help. Thank you, Maria Sergeevna.
