The fact that Dr. Maditz took the time out of his busy schedule to help me set up a video link speaks volumes about his concern for his patients. What he did for me was an incredible help- at a time when I was rescheduling everything under the sun, He took my appointment off my checklist of problems. I''m very grateful.

I recently saw a nephrologist, and I really liked him. He had reviewed my chart ahead of time and was well-prepared to answer all my questions. He is young, very professional, and clearly knows what he's doing. I was very satisfied with our interaction.

He is my favorite doctor. He not only explains his worries/non worries and why thoroughly he also asks me about status of what I think are ancillary issues and medical conditions. Plus he is empathic, easy to open up to and funny
