"I was comforted by the fact that Dr. Nhan had already looked at my previous history. I also enjoyed that Dr. Nhan had addressed me and my life partner about my care and was through in their explanation of why I was to make some changes. Dr. Nhan gave their advice and ultimately it was up to me to make the final decision. In all of my time as a type one diabetic I've only had one other doctor speak to me as if I'm apart of the team and I've had several primary care and endocrinologists. Dr. NHan is an excellent doctor."
