The Indigenous Cultures Speakers Bureau provides lectures and presentations by professional presenters, on a sliding-scale-fee basis. Topics include little known historical and cultural information about the Coahuiltecan people and general education about Native Americans in Texas. We offer lectures for college and community audiences, and presentations are available for schools.

Our presentations inspire a new awareness and deep appreciation for the past and present-day contributions of Native Americans. Please contact us to inquire about the speakers’ fees and to schedule one or more of the following lectures or presentations.

If you would like to engage one of our speakers, please email LaRay Guerrero at

Marika Alvarado

I am Marika, a Lipan Mescalero Apache. I am a direct descendant of generations of Medicine Women: traditional native healers of spirit and body, midwives, and plant medicine practitioners. My mother, grandmother, and aunt handed the medicine down to me. I am here to help in the healing of others and to pass on these teachings I have been given. I believe that I should teach all people who have the dedication and spiritual will to use these teachings as Mother Earth and the generations before me intended.
