Valley Hope has A LOT of treatment centers, including the ones in Kansas. Searching their website is pretty easy:
Valley Hope Association - Alcohol, Drug and Related Treatment Services
The only person I ever knew to comment on the center's success was an alcoholic who had an alcoholic daughter whom he sabotaged from getting treatment, probably because he had no intention of getting help himself. Needless to say, he thought Valley Hope was a waste of time. I guess what you think of a treatment center's success depends what your goal is.
