She told me I needed to get another Colonoscopy which I did not know. She said it was important to get another one at my age. I told her yes based on what she shared with me. She is an excellent doctor that I trust.

Greets me smiling, asking how I am, very friendly, treats me like family. She listens and answers any questions I may have. She's very knowledgeable and shows concern for me.
