Consulted Dr. Ajay Narasimhan
He is a very down to earth person. Such a young man physically but to me he appears as GOD. He gave life to my husband. I owe it all to him.Easily reachable and very professional. I would say that many of the so called busy doctors must learn from him to be empathetic. He picks up my calls and patiently answers all my questions.in case he is busy he messages immediately and would revert back KUDOS to Dr.Ajay Narasimhan!!
