“I was able to get a very quick appointment like the next day I got in. I didn’t have to wait long. I was able to get out fast, go get my medication right across the street at CVS and get home to rest, loved it. Dr. Coats does not need to spend 20 minutes talking to you. He’s very knowledgeable and doesn’t waste unnecessary time.”
