Dr. Mariorenzi was professional and very clear in answering our questions fully. He was particularly careful with my wife who has serious hearing loss. He outlined the two available medical interventions and explained why one would be preferable for medical reasons. He provided handouts to guide us in managing my wife's medications. It was a very comfortable and successful visit.
