He's an amazing Dr, listens carefully and doesnt rush the time with his patient, shows serious concern about patients.
Such a caring and knowledgeable Doctor. Made me feel very comfortable and confident in his care. And, the office staff was very attentive and nice. I'm very impressed with the team.

I've been seeing Dr Nannenga for three years. I have nothing but good things to say about him and his treatment of me. He is willing to involve me in his recommendations about my treatment rather than simply dictating what I should do. He is very knowledgeable and caring.
in Kingsport, TN |
Dr. Nannenga cares about his patients and any negative reviews, based on my experience, are likely from people who only visit the doctor for what they want to hear. He won't give you a load of reasons why something is his it is, he gives you facts, something many doctors today have a difficult time getting to because of their lack of knowledge. He's thorough, educated and devoted. Highly recommended if you want the truth, but not if you're only looking for sugar coating or pills.

Unfortunately Dr. Morris retired and I was left with this new doc, Dr Nannenga, who was very rude. I had been diagnosed in 1995 for Hypo-Thryoidism, and then Dr. Morris diagnosed me with Hashimotos. When Dr. Nannenga took over and I saw him for a follow up of a Thyroid Ultrasound for a Goiter and blood work review as well as possible medication adjustment. This man had the audacity of telling me that my ability to lose weight had nothing to do with my diagnosed conditions, that it had everything
