I am SO GRATEFUL that UAMS provides patient transport--my knee was hurting so bad yesterday and patient transport got me from cardiology to the lab and back down to the front door. I don't think I could have walked that far. Patient transport is one of the best things about UAMS. Seriously. Everybody I encountered in the cardiology clinic was helpful, kind and friendly.

Yes, I love Dr. K. I felt like she really had listened to me the first time I was in there. She knew what my concerns were. She addressed them thoroughly. She listened and she explained things really well to me. I was leaving not sure about how I was doing. I felt encouraged for the first time in a very long time about my health. So I just want to say thank you.
