Haven’t said hi yet, so hi! 
I heard of two ones… something in Peru I think @jean_russell do you remember that guy who was at the retreat in Thailand with us? I don’t have the catalogue with description of participants…maybe @christina_jordan knows?
Another one is the Amish, Alberto wrote about it here.
Then there is the Greek network of shadow clinics.
Also @woodbinehealth might know of some? Maybe also @markomanka ?
