It is really a must read.”

“I just finished your book and cannot thank you enough for putting this resource together. It’s such a valuable, practical and well-explained guide. I’ve already recommended it to several patients and some of the MCAS/POTS/EDS communities I’m involved with. I have my own history with mold and it seems to make up a big part of the puzzle for so many of the patients I work with.

A Walker

It’s people like you that make the world a brighter place. I just finished reading Break The Mold, ahhhhhhhhhhhhhhmazing!!!! So much digestible, tangible information and just such a blessing of hope for those of us who struggle, despite doing all the things.”

What Experts Are Saying

“Dr. Crista has written one of the best “get right to it” books about mold related illness, causes, treatments and most importantly the process of healing. In three decades of helping very ill patients I have come up against mold and mold related illness repeatedly and struggled to find good (and complete) patient resources. ‘Break the Mold’ is just such a resource and I plan to recommend it and use it in our clinics.”
