Dr Ashutosh Singh is the best doctor and cardiac surgeon for children. Also a wonderful and down to earth person. He is a very simple, starightforword but highly skilled, talented and amazing individual. He did PAH surgery for my daughter and she is healthy now. I don't have enough words to say Thank you to you sir! Dr Srinivas, his teammate who also does 2D echo for patients is also a very good doctor. God bless both of you and our best wishes with you. Please do continue to save lives of children and their families. Thank you.
