Hippocrates is an excellent choice. Brian is a great guy. They have helped many people heal from all kinds of cancer. A friend of mine studied there for 6 months.
Also, in Mexico, check out Sanoviv http://www.sanoviv.com This is a beautiful and fabulous facility in Rosarito. I know a few people who went here and rave about it. I have also called them and read through their protocol book. They are top notch!
