Also, I meant to add that Peter Walsh isn't dealing with those extreme hoarding situations like on the TLC show. you'll notice he rarely if ever even uses the word "hoarder." I think he goes in and assesses the situation looking to see if the person genuinely wants help and is willing/ready to purge or if they are mentally unable to do so....and he passes if it's the latter. He is similar to that Clean House show, where again, the people are indeed very cluttered/messy, etc.. but the difference between them and those on the Hoarders shows is they aren't in such deep denial of the situation they need to get a psychologist in to hold their hand through every little step of the cleanup.
