I have been to this facility twice. On both visits, the wait time was extremely long. In this appointment, my appt time was 10:45am. I was not called back until 12:10pm. During my first visit, I saw the doctor and had to have lab work done. I waited over 90 min just to be called into the lab to have blood drawn.

My visit today at WellStar was outstanding, from check-in to the nurses, to speaking to the doctor's assistant, as well as the doctor. Outstanding experience. Everything was done in a timely manner. Everybody was very respectful, didn't talk over my head, made it very easy to understand. Outstanding experience.

Patients need guidance about virtual visits. I had no idea if I was supposed to call the office or if the doctor would call me. I tried for 25 minutes to even talk to a person instead of voice mail to find out the doctor would call me when available between patients.
