Excellence from start to finish! From the prompt call backs, the details given by Mark, and the patience and time he takes to explain each process, the compassion he shows for your health, to the time Dr. Stanga spends with you, listening intently and then mapping out a health plan after examining your test results, I am thoroughly satisfied. But what's more is that FINALLY I'm on the road to recovery. Finally I have peace of mind feeling my physical and mental health starting to improve. I have nothing but the utmost praise and thanks for Mr. Mark and Dr.Stanga, and such relief that the weight of ill health is dissapating along with the fear that I was never going to feel well again. Thank you so much!!!Jeffrey D.S.
