    Dr. Mutter, I have seen him now for quite a few years for my kidneys, renal arteries, and he's an excellent doctor. He listens very carefully to what I say. He answers questions in detail, and he is never in a hurry. He always takes his time, answers my questions, and gives me all the time I need to talk to him and for him to explain everything to me. He's really a great doctor. Very, very kind and very compassionate. I'm really glad I have him for my kidney doctor.

    Dr. Mutter is a fabulous, not only a wonderful nephrologist, but is a fabulous doctor in general. He clearly is brilliant. He knows this information and his field in detail superbly. But he's also caring and concerned and just very dedicated to the well-being of the patient, in this case me. And he also has given me advice about issues that are tangential to my kidney disease. Other things that relate to the kidney disease but are not necessarily directly nephrology. So I think we're extremely lucky to have him and I have recommended him to others and will continue to do so.
