I've lived in Seattle for 20 years and NEVER heard of this place before a poster came here and talked about it. I've been to several naturopathic doctors (graduates of the highly reputable Bastyr College) and not one ever suggested or mentioned this place. My last GI doc, the #1 guy in town, sent me to a holistic clinic for additional help yet never mentioned this place. My PCP, whom I have seen for 20 years, never heard of this place.
It might be legit, but because I've lived here so long, and have run in the "holistic" circles with people who should know, I am skeptical. I am also out of work right now (and consequently, insurance) so I can't really check it out. I'll file it away for future reference.
