Dr. Johnson is clearly knowledgeable and is thorough and thoughtful, which was refreshing. In general, he really heard what I was saying to him and asked appropriate follow up questions. I feel seen, heard and supported.

I felt Dr Johnson took the appropriate time explaining my situation to me and being very honest about how we were going to take care of it. I really appreciate him. He’s very kind I also want to add his nurse Connie is so sweet and amazing

Dr. Johnson was very sensitive to what I came to see him about, and was a great encouragement to what the outcome would be. And he was correct.

Dr. Johnson went above and beyond to work me in on very short notice so we could leave for Florida tomorrow as planned! It was such a relief to be able to discuss new test results with him before leaving so it didn’t hang over my head for 4 months. I have been so appreciative of his attentive care in the past and again today. Dr Johnson is a perfect example of Extraordinary Care, Every Day!

Dr Johnson was very informative as well as he did not hurry through my appointment. He explained things and told me what will be in store for me. I like to know what I have to look forward to.
