    Dr Buster was great!
    Dr. Buster does a great job.
    One thing I do not appreciate is extra people taking notes for the doctor, etc. Once there were two of them at the time I wanted to talk with the doctor and I felt uncomfortable talking about delicate matters and infection so I asked them to leave. This time there was only one, same problem. I do not want to kick them out, but they have to respect privacy and should ask to be admitted rather than me asking them to leave. What actually happens is that the doctor is distracted and speaking to the scribes and asking them what information they have without actually reviewing the information from test results and speaking directly to me, the patient. I want the direct attention for the few minutes I actually have for a doctor visit.
    Dr. Buster is a good listener and always takes time to explain things in an understandable way. I have seen him for many years so he knows my history well and I trust his judgement.
