Dr. Ranga Rao is a best Doctor for any patient. He goes to any length to provide best treatment.. He not only proscribe medicine but give us confidence and moral support. I have been under his treatment from 2009 when it was diagnosed. He clarify all my doubt without any sign of frustration. He gives full attention and listen to all the questions we have and provide solutions wherever required. I highly recommend him to all. The way he interact and involved with his patients is beyond words. I am lucky to have him as my Doctor.. Best of luck Dr. Rao..
