Dr R R Kasliwal is such a nice person, He spent good amount of time listening to the symptoms, also discussed the history and diagnosed with some tests to make sure our concerns are answered in a right way. We had some clue on the problem we went to him for and he also concluded the same. On top of that he made us so comfortable that we didn't even realized that we are meeting for the first time. Over all, he is not just a very good cardiologist but a fantastic human being. I have seen many cardiologist with various levels of experience but this was the first time I've seen one who is so much down to earth, all-ears, lively and understanding. I'll suggest and recommend him in all good faith.

@Akash sagar I agree @swadesh that Escort is a good choice in Delhi.

My mother in law had undergone pacemaker surgery in Escorts 5 years back in 2010. That time we chose Escort after some feedback we had from friends. Surgery was done by DR TS Kler , He was head of department there.
Dr TS kler is very experience doctor and expert in handling complex cases. My mother in law is doing fine. Escort hospital is well equipped to take care of emergency situation. So we had no doubt on expertise there. But during operation and after the operation till the patient is in ICU no room is given to attendant so we had to wait in the lobby through out the night, Not sure what is situation now.
Billing was very smooth , we had insurance cover.

My Father had undergone 2 Angiplasty & Angiography. 1 in Metro Hospital and 2nd in Escorts. Both are good. But prefer the Excorst as the good doctors have moved out of Metro to Escorts Hospital

There is already a discussion going on around Best Pediatrician in Gurgaon You can go through that thread and if you have any further questions pl post there to ask the people engaged in that discussion.

Dr Anuj Dhama is very good .No airs around him , gives you patient hearing , diagnosis is bang on and explains the illness thoroughly. with him I feel safe for my child. His clinic is in sapphire on sohna road behind omaxe mall.ph ; 8800744119

Dr Mangala Pawar. she has her clinic on Sohana road (Sapphire Mall) and in NIrvana. One of the best pediatrician I have ever met. I used to go to galleria to so called famous doctor for my first baby but was never impressed. Dr mangala has vast experience but is new to gurgaon and hence not famous yet but she has a very promising career. i feel my newborn (second baby) is safe in her hands,and i am learning so many new things in childcare event hough i am second time mom.i strongly recommend her.
