My experience with Max hospital gurgaon is generally good. Though we found it bit expensive. We consulted Gynecologist Dr. Deepa Dewan and Pediatrician Dr. Himanshu agarwal. Both are polite and speak to the point. What I found great was that both provided their whatsapp no. through which you can contact them in case of emergency. This was really helpful during the maternity period of my wife and early years of our son.
