Dr Mazziotti performed the nuss procedure on my 15 yr old son on Monday ( 12/29/14) The results are AMAZING and things went way better than I could have ever expected. Dr Mazziotti makes himself easily accesable to his patients and listens to all of your concerns and answers all of your questions & takes time to explain things that you may not understand. He also has a wonderful bedside manner, which was very much appreciated by us. I am VERY pleased with Dr Mazziotti and the entire staff at Texas Children's Hospital and everything they did for my son
