Dr Little is an extraordinarily learned man, actively engaged in pioneering research in this field as well as running an extremely busy practice. As such he may occasionally come across as distracted or distant, but you can absolutely depend on his advice and treatment. The treatments require discipline and this is hard for many patients who want a quick fix. He is compassionate, dedicated, and brilliant. I spent over 10 years with an increasingly debilitating illness, where I had seen multiple specialists over the years who prescribed multiple medications, none of which seemed to help until I came across Dr Little. I accidentally ran into him whilst in a hospital unit in which there were several of his patients. After extensive testing and a very rigorous regime of exclusions, my health improved dramatically, to the point where I needed no more medications. Before this I would never have guessed that the broad range of symptoms I had could be allergy related. Note that the treatment took several years, but my quality of life went from zero (bedridden) to being able to live a relatively normal life and recommenced employment.
