- 5 out of 5 starsReviewed on 6/18/2024
Dr. Sperati was incredibly knowledgeable about all of my pre-existing conditions (something I do not usually find in doctors) and how they might affect my kidneys. Having looked at the labs that I had previously done, he was able to give me an Idea of what was going on and what to expect moving forward. He was extremely thorough, kind, knowledgeable, and understanding. He reminded me why I used to have most of my doctors at Hopkins and why I need to do so again.
