A friend, who is a physician in the U.S., told me that many doctors make mistakes in their treatment of patients. Actually, this isn't exclusive to that country and the main reason this happens is because of miscommunication among doctors who treat a particular patient. Oh, I see... 

With Doximity, a social networking website only for doctors, physicians in the United States in particular, one could easily search for the contact information and medical training background of a doctor, no matter where he or she is based in the country. 

I tried searching for Alexander Gomelsky MD just to test out the search engine and I like that the profile of the doctor is informative and complete.
