2019 Helpful People Poll: Which Individuals Do Mold Group Members Believe Helped Them?


February 27, 2020

By Lisa Petrison, Ph.D.

For each of the past four years, I have conducted a poll in the most active mold-oriented Facebook groups asking participants which medical practitioners had been helpful to them in terms of facilitating health improvements.

This year, however, many participants stated that other individuals had been much more helpful to them than any medical practitioners had, and requested that make an effort to recognize those individuals as well.

I therefore conducted a poll in six large mold-oriented Facebook groups asking the following question:

Since starting mold avoidance (of whatever sort), has there been anyone who has been helpful to you in addressing your mold-related illness symptoms?

Please check only those individuals who have been at least moderately helpful to you in terms of addressing your own chronic illness issues.

The help provided may have been with regard to avoidance issues, adjunctive healing issues, or anything else that has made a significant difference in your health.

If you have been a patient of a healthcare practitioner, please do not mention that person here (since those individuals are covered by a recently conducted separate poll). However, please feel free to list healthcare practitioners that have been helpful to you in other ways (such as by writing books or articles), as well as anyone else who has been helpful to you in any way.

This poll is being shared in a number of different mold groups. Please participate in the poll only one time total.

The results of this poll will be summarized in an upcoming Paradigm Change blog article.

Thanks much for your participation in this poll!


The poll was first shared in the Mold Avoiders group on December 26, 2019.

It then was shared a week later in the same other five groups as were used for the 2019 Medical Practitioners Poll.

A total of 200 individuals participated.

The participating groups were Mold Avoiders (88 participants); Practical Mold Avoidance (52 participants); Toxic Mold, CIRS & Lyme Disease Support Group (21 participants); Surviving Toxic Mold (14 participants); Toxic Mold – Rediscovering Health and Wellness (13 respondents); and Toxic Mold Support Group (12 respondents).

Mold group members 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.

Participants were not permitted to vote for themselves.

A total of 161 individuals were mentioned by at least one respondent, and 52 individuals received at least three mentions.

A total of 12 respondents (6% of the total) checked the following option in the poll:  “I have not had anyone (including any medical practitioner) be at least moderately helpful to me since starting mold avoidance.”

Although the instructions stated that participants should not vote for practitioners who had treated them, cross-checking the responses against those of the 2019 Practitioner Poll suggested that almost all mold group members participating in both polls had checked practitioners who had treated them in this poll as well as the other one.

Therefore, for those individuals who had mentioned practitioners in the other poll, I made sure that those practitioners also were given credit for that mention in this poll even in the small number of cases where no mention of the practitioner had been made in this poll.

Although I am very honored to have been reported as having helped so many people in this poll, I would like to point out that I acquired virtually all of my own knowledge about mold avoidance and much of my knowledge about other topics from Erik Johnson.

And that therefore, insofar as people have been helped by me, they have been helped by Erik as well.
