    My experience with my care provider was extraordinary. As a nurse practitioner myself, she displays all of the critical thinking characteristics that I come to expect from all my providers at UCSF. But in doing so, she makes me feel at home and as part of the team. We share decision-making. my provider was like coming back to see a really close friend. And that's really the kind of relationship. I have with the entire staff and team at UCSF. They define the paradigm of healthcare to what it should be. My provider was a delight to visit with him to , get guidance from.
