I got an appointment when I needed one.
They kept things moving and on time during my visit.
I received a correct diagnosis and up-to-date treatment.
I was given specific advice on lifestyle changes I can make to improve my health.
The provider really listened, gave me the time I needed, and put me at ease.
We discussed treatment options and choices I have.
The provider addressed traditional and alternative medicine treatment options in an open-minded way.
