In the back of Dr. Rapp's  other book "Is This Your Child's World", there are
many, many references.  Not just for in the US but other countries too.
 There's references for doctors (or places to get referals) , products,
testing and much more.  There is a number for the American Academy of
Environmental Medicine in Kansas. (913-642-6062) It says that "they can
provide the name of the nearest EI specialist".  Maybe that would be a place
to start.  I called and they gave me a number for a Dr. about 1 1/2 hours
from my home.  I think I'd rather travel that far than hop around from dr. to
dr. in my area trying to find the right one.  I'll let you know what happens.
