My rating for Doctorspring is 1, for the doctor 5. I was deceived by Doctorspring, being misled by deceptive advertising that implied that I would be answered by a doctor in the US (the page showed the message "Waiting to answer" with a picture of a cardiologist with training and experience in the US). But my questions were instead given to an Indian physician with no training or experience in the US. I am posting this review of Doctorspring to warn others about their deceptive practices. The doctor's answers were good, given the limits of his training, so I have no complaint with him, and would not even want a refund, as he should be compensated for his time and knowledge. But beware of the website Doctorspring.
