Our professor is not only a highly valuable doctor but also a wonderful person. His care, attention, and support during my father's treatment meant a great deal to us. Thank you for everything, dear Professor.

Our doctor Omur is not just a physician — he is a role model. With his understanding and cheerful manner, he managed to convince my father to undergo surgery — something no one had been able to do for two years. It seems it isn't always about knowledge, but also about the ability to communicate with the patient! There is no need to mention his intellect, medical skill, and ethics. I wish everyone could meet doctors like him.

A passionate, caring, dedicated, and incredibly successful hematologist. On top of all these qualities — the most humble doctor you will ever meet. He explains, understands, reassures, and you realize you are in the very best hands. His visits during the bone marrow transplantation process fill you with morale and energy! Thank you, Professor Gokmen!
