Dr Ganz was empathetic and acted fast to not only relieve my immediate discomfort, but has made a plan to get to the bottom of my symptoms. I did not feel dismissed, but I felt heard and respected

I appreciated that he was willing to take extra time to explain his opinion of my condition and to reassure me that I did not have a serious problem. He has a pleasant personality and a confident and professional demeanor.
