    I was very pleased with my visit with Dr. Barnes, whom I was seeing for the first time. He introduced himself and told me a bit of his background. He had already reviewed aspects of my medical history pertinent to my current diagnosis, and asked me many pertinent questions. He gave me a great deal of information relating to the lab tests I'd had recently, and what their results might indicate. He also gave me a lot of information about new tests he felt were indicated, and what their results might reveal. Throughout, he was encouraging and reassuring in terms of what the findings might or might not be. I had plenty of time to express what my goals were for the appointment , and ask to questions about what he presented to me. He was careful to define any terms he felt might be unfamiliar to me. I went to the lab after leaving the appointment. When he phoned me later in the day to talk about results that were already available, I was amazed and impressed. I liked that he referred to himself as Jeff Barnes (not "Dr Barnes") twice. It's a small detail, but telling, in my view. I'm grateful that I was referred to this practice, and will see him again for follow up.
