This Dr. is antagonistic and not compassionate. He answers questions with sarcastic questions. His favorite line is "I don't have a crystal ball". He does not offer explanations of treatment, medications and treatment plans. When asked a question, he acts bothered and responds with antagonistic answers, such as, "I already explained that to you last time." "I don't know." or "Haven't you taken this medicine before?" We have left this practice and do not recommend Dr. Khan to anyone.
