Dr. Rosen is perhaps my favorite health care practitioner ever! He is knowledgeable and takes the time to answer all my questions, but beyond that, he is kind. He goes the extra distance to ensure that I am healthy--taking the initiative to order tests and monitor my condition in a way that other kidney specialists would not. He has guided me to restore my health so I no longer need to see him any longer, and I am kind of sad about that! He's just the best and I'd recommend him to anyone.
