    Dr. Nannes gave me his full attention and was completely tuned into me and my medical needs. He listened carefully and was well aware of past reactions to medications, when discussing options for treatment. He was easy to talk to and receptive to my comments and ideas. The practice of medicine is a combination of both science and art and he met that mark beautifully. I feel he has been an excellent doctor for me and I believe we have a very good partnership in overseeing and guiding me through my health needs.
