Dr Hagaman was patient. He was engaged and lean in to listen. He is an excellent teacher explaining terms, meditation and symptoms to me.

I could not be happier with the care, attention and results I got from Dr Hagaman. I spent three years with another local doctor, with no discernable results. It took Dr Hagaman about twenty minutes to diagnose the problem and prescribe treatment. He even discovered a problem with my lungs and referred me to the Vanderbilt Lung Institute. My lungs are now healthier than I have been in years.
