The Paradigm Change mold practitioners poll allows individuals participating in online mold groups to share information about which medical professionals have been helpful to them.
The goal of the poll is to provide recognition to those practitioners who are thought by patients to be particularly helpful and also possibly to gain insights into the practitioner characteristics that are especially valued by patients.
This year’s poll question read as follows:
Have you consulted personally with any medical practitioners who already have been helpful to you in addressing your mold-related illness symptoms?
Please check those healthcare practitioners who have been at least moderately helpful to you in terms of addressing your chronic illness issues.
If there are additional practitioners who have been helpful to you, please write their names in the comments.
This poll also will be shared in other mold-oriented groups on Facebook. Please participate in the poll only one time.
The results of the poll will be shared as a Paradigm Change blog article.
Here is a link to the 2017 results:
A list of mold-oriented practitioners may be found here:
Thank you for your participation in this poll!
Practitioners who had received two or more mentions in the 2017 poll were listed as the initial choices for all groups.
The poll was conducted in seven different Facebook mold groups. A total of 173 individuals participated.
The poll was first shared in the Mold Avoiders group on June 28, 2017. It then was shared in the other groups a week later.
Individuals were instructed to participate in the poll only one time, and participant names were checked across groups to make sure that no one had participated more than once.
Practitioners were not permitted to vote for themselves.
A total of 89 people in the Mold Avoiders group participated.
The other groups where the poll was posted were Toxic Mold, CIRS and Lyme Disease Support Group (17 participants); Toxic Mould Support Australia (24 participants); Surviving Toxic Mold (8 participants); Toxic Mold Symptoms (7 participants); Toxic Mold – Rediscovering Health and Wellness (18 participants); and Toxic Mold Support Group (10 participants).
A total of 104 different practitioners were mentioned by participants, and 31 practitioners received at least two mentions.
About 23% of all participants (39 individuals) checked the following response: “I have not yet found any medical practitioners to be at least moderately helpful to me.

Please note that the results of this poll should not be taken to suggest that the individuals who received the most votes are definitely the best mold illness practitioners out there.
There are many reasons that a practitioner providing quality care to mold illness patients may not have come up with very many mentions or even any mentions in this poll.
For instance, practitioners may be relatively new and not yet have built up their practices; may be serving a patient population consisting mostly of people who do not participate in mold groups; may serve a limited number of new patients or patients in general; or may have patients who just happened not to see the poll when it was posted.
Note also that the methodology of the poll limited responses to those who had had positive experiences with these clinicians. Insofar as some mold group participants had seen clinicians but did not find them to have been helpful, this would not have been reflected in the poll results.
Please understand that the listing of physicians and other medical practitioners in this blog post does not constitute an endorsement or recommendation by anyone associated with Paradigm Change. We do not suggest that individuals actually become patients of these professionals or follow their treatment recommendations based on their inclusion on this list. Mold illness is an emerging area, not all patients may benefit from the same treatments, and our knowledge about these practitioners is limited (in some cases, based on a single reported experience from someone who we do not personally know). Practitioners listed here use a wide range of treatment modalities, most of which may not be appropriate for all situations. The information provided through the sharing of these poll results is at most provided only to give patients a starting point with regard to doing their own due diligence in terms of learning about and interviewing practitioners that might be appropriate for their situations. Best of luck to all with regard to finding a practitioner appropriate for your situation.
