Dr. Osman is literally one of the best pulmonologists I've ever met. I visited him as I was suffering from burning in my lungs and difficulty drawing a breath. Speaks perfect English and is very parient. Communicated my case specifically and patiently. Prescribed what I needed to take. I'm coordinating with him for my case, but as a tourist here in Istanbul, it's rare to find good doctors. Dr. Osman is very highly recommended.
