This was my first meeting with Dr Nealis. I found him very personable and attentive to my needs. He apparently had access to all my records and used them during our call. On the basis of my records and our conversation he ordered further testing in an effort to achieve a more reasoned diagnosis of my issue. He left me with a high degree of confidence that he will get to the bottom of my issue and provide a satisfactory resolution.
