I am extremely grateful for the discussions and treatment. Dr Loftus reassured me that I am not losing my mind and the treatment that he gave me made me feel much better, essentially symptom free.

I liked him and his knowledge of my illness. I was encouraged by his recommendations.

He has been named a Texas Monthly “Super Doctor” and an H Texas magazine “Top Doctor” multiple times.
