In July 2019, I had an operation to remove my stomach due to cancer. The operation was performed by Oleg V. Ishchenko. Our whole family is very grateful to you for the professionalism, sensitivity and skill of the surgeon! The operation was successful, and so was the recovery. I am very glad that in our country there are such wonderful doctors who can be trusted with their lives. THANK YOU very MUCH!!!! To you, my dear doctors OLEG VADIMOVICH and ALEXEY YURYEVICH!!! I wish you health, success, prosperity and a lot of positive things in your life! God bless you!
