    My only concern is, when ever I do book an appointment for any reason 99.99% of the time I see someone else. This is the first time I have seen Dr. Diamond in years. The previous health care I was in I saw my doctor at least 80% of the time for visits. While I understand doctors are busy, there are just some times I would like to see a doctor, specifically the doctor I selected as my primary.

    Good experience and discussed all of my concerns. I wish Medicare well visit was more like an old fashion physical and I feel certain aspects of physical doesn't occur such as skin exam, ears, EKG but this is fault of Medicare not provider. I feel drawing a clock, and remembering words would be better substituted with the above.
