    I had a lot of questions for Dr Wallis, and he patiently answered them all. He has reassuring without being dismissive. He did not sugar coat the difficult parts of my son's case, but I left our appointment feeling better than when I came in. I felt like he respected me and my son, and that he genuinely wanted my son to have the best quality of life possible.

    Very much appreciated him. Saw him for the first time after seeing someone else for two years and he answered questions no one took the time to answer. I felt more reassured after this visit than I did in the last 3 years.
