Dr. Srivastava and Han made me feel super comfortable. I did not believe the reviews at first... But now I see. Dr. Srivastava listened to me and also educated me about my health condition. He seems to be a people's person and genuinely a nice human being. The staff at the Greenbelt office are very kind and very informative!! Everyone Smiled!! That for me is one of the most amazing feelings. Walking into a doctor's office as a new patient and leaving with a smile knowing that you made the right decision!!
