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.

Marika Alvarado

Marika Alvarado (Apache) is a traditional healer trained in the use of Native methods that have been handed down to her, generation to generation, from the women in her family. Working in harmony with the plants of the earth and the rhythm of the body, she uses her hands to assist the body, mind, and spirit in healing itself. She also uses knowledge of native plants in the forms of teas, tinctures and creams that she creates. Her work is in its purest, traditional form; nothing has been changed or newly created. She teaches classes in traditional medicine and conducts plant walks.
