“I had a heart attack followed by open heart surgery 8 years ago. I have seen Dr. Nasir at his office in Chinatown on a regular basis thereafter. He is a great listener. He always questions me rigorously and thoroughly. I believe I am still alive because of his care and concern. I enthusiastically recommend him. Samuel P. in downtown Chicago”
