    Waited for 3 hours. Dr. Greenspan was very rude and unprofessional. Heard him talking very loudly and rudely to another patient before he came in and treated me also very unprofessional and rudely. He talked to me like I was stupid and I left his office crying. He was like a giant bully. Worse experience I've ever had with a Dr. DO NOT GO TO HIM!!!

    He is very unprofessional he is not honest. He does not do the job he should be ding to help the people that has to go see him not by choice. He can mess up people's life with his reports not like to fill out forms Fpr what people need. Woudl not go see him by my choice. Dr Sisto is way better

    Excellent care. Answers questions in detail. Refers to well qualified specialist, when needed. A+ rating.

    He talks in circles, doesn't really seem to listen. Gives his theories and comparisons which he thinks will appease you at least that is the impression on this side. He is almost dismissive.
