Listens very well. Excellent bedside manner. He has had some excellent support staff & some he could have done well to not have hired. All staff is bilingual, but some of his clinical staff has been difficult to communicate with. My first language is English. Some of his staff does have trouble communicating with me. Communication has never been an issue with Dr. Marrero himself.
