Very few clinics can say that the chief doctor do ALL the work himself. Most hair transplants last several days and include few sessions per day. So I think it would not be possible to demand that the doctor does all the work. That is why we need to research and find the clinic with best and consistent results.
And also, I think Dr. Ozgur is more involved than Dr. Koray of ASMED, according to some reviews I read. If you want a more extensively involved doctor in Turkey, you would have to go for Dr. Keser. He does only about 500 grafts. So for 3000 grafts case, it would take about 6 days, seems a bit too extreme for me.
