Mould Illness:

Biotoxin Journey

Written by Greg Minske, a former construction contractor and math teacher, this website is thorough, scientific, and straight forward.   Greg shares his own experience with mould illness, gives a very thorough overview of the Shoemaker Protocol for treating mould illness, and shares details of how he tested and remediated his home.

Surviving Mold

This website outlines Dr. Ritchie Shoemaker’s protocol, a well known and researched approach to treating mould illness.  This physician is, by all accounts, the first physician to seriously look at illness from biotoxins (first, illness from ciguatera from fish, and at some point after, illness arising from water damaged buildings.)

Paradigm Change

Written and maintained by Lisa Petrison, Executive Director of the non-profit, Paradigm Change, this website is focused on the role of mold in chronic illness.  One of the primary goals of Paradigm Change is to support research into the role of mold in chronic illness.  This website has an astounding amount of information, including consolidated surveys from people with mould illness who practice Mold Avoidance.
