I have been coming to Dr. Diamant for over two years now. He is very knowledgeable and has been treating my asthma and other pulmonary conditions quite successfully. He also has after hours service in emergencies.

He has terrible bedside manner. He likes to fear monger and have his patients continue to order multiple tests to profit, he tried reordering the exact blood tests I took the week prior with my primary until I caught him. He avoids eye contact and has a strange bedside demeanor, not helpful at all.
