I really like Dr. Hernandez. During my visit he covered numerous aspects of my overall health. He has a caring and empathetic manner. Trinity was the medical assistant that took my BP and went over my scripts. She also gave an EKG. She was thorough, professional and personable. I like this office, everyone involved from the ladies behind the reception desk downstairs to Dr. Hernandez do an exemplary job of representing The Wellstar Health System.

I am very pleased with Dr. Hernandez. I have been seeing him for 10 or 11 years now. However, as far as the WellSAR policy on giving your provider 15 minutes to have your appointment, talk with him, and all of that, I think that is charged way too much for that little time. That is something that needs to be addressed in the past. It doesn't seem like he has been rushed until the past probably, I don't know, three years or so. And then it looks like he is trying to maintain a schedule that has been set forth for him, which I don't think is a proper way to do customer care.
