Excellent doctor, I wish you didn't call every time after I visited doctor. I see multiple doctors and get a call every time it's excessive.

I don't think it could have been better. All my questions were answered. If there was no answer, they said so. Dr Yang and PA B.Nivens are top of the line in my estimation.

not ask me to come in earlier than appt time and then not get in patient room 15 minutes after original appt time

Have more than just one person who can schedule appointments. Having only one person who can perform ANY function is ridiculous.

Place a sign in the hallway that can be seen from down the hall. It is hard for a new patient to see where to go. ??

I've never had such a great experience with the doctor in that field as I've had a bad experience not very long ago with another doctor. So I'm very happy with this and hope to continue to see him.
