CFI Speakers Bureau


The Center for Inquiry (CFI) Speakers Bureau is a tool for campus groups, community groups, and conference organizers to find quality speakers on topics related to CFI’s mission of fostering a secular society based on reason, science, freedom of inquiry, and humanist values.

If you would like to book a speaker, you may email them at the address provided on their profile. Unless indicated otherwise, CFI does not typically act as an intermediary between speakers and groups.

“CFI Speakers” are staff, board members, and volunteer representatives.

If you have questions about the CFI Speakers Bureau, please contact the CFI Outreach Department at outreach@centerforinquiry.net.

Viewpoints and information presented by speakers do not necessarily reflect the viewpoints of, nor should they be attributed to, CFI or its affiliates, or any of their directors or officers.
