great dr. very caring. believed me when I said I wasnt well, even though what was wrong wasnt visable. Took my concerns seriously, took care of getting me a CT as an emergency, and then got me admitted. He even got me the first surgery of the day so I could leave the next day. I felt so grateful to have a great dr.

Dr. Greenwald is rude and condescending. He does not know how to speak to other people.

I gave an I don't know about diagnosing a problem because I don't know. Only time will tell if his diagnosis was accurate. Otherwise he's your typical surgeon. Have been told that he's top in his hospital. His bedside manner is that of a surgeon, that's why they become surgeons and not pediatricians. He takes plenty of time to explain things and answers questions.

Dr. Greenwald is an excellent doctor. Great personality and mannerism. However, his office and billing staff are incompetent and very impolite. I called the office to confirm if my insurance is accepted and they said yes. I then made an appointment and gave them my insurance card and they charge me the co-pay. Approxmiately 5 weeks letter I receive a bill for over $600.00 dollars because they did not accept my insurance. I tried to talk them and got no where, now they put me in collections. I am very dispointed in the way my case was handled and due to Dr. Greenwald's staff I will not return nor recommend him to anyone. "You get more with HONEY then VINEGAR" is a lesson his staff should learn.

I was very happy with Dr Greenwald. He has beautiful, modern facilities and competent staff. Dr. Greenwald took all the time needed to fully explain my situation in a way that made me feel comfortable making a decision.
