As a Mandan and Hidatsa historian, I specialize in giving PowerPoint presentations on my people's culture and history. During the Lewis and Clark Bicentennial, I presented a contemporary view of our tribe's involvement in the Lewis and Clark Expedition, featuring the oral tradition about the Hidatsa origins of the Bird Woman; in our Hidatsa language, Sakakawea. For a complete list of my presentations, please refer to the list below.

I have thirty years of professional experience in communications, public relations and cultural preservation. I testified on behalf of my people before Congress in Washington, DC in 1992 for the establishment of a $149.2 million trust fund. In 1998 and 2000, I traveled to Germany as part of an historic delegation representing my people.

I recently completed a Mandan Language and Oral Tradition Preservation Project with Dr. Joseph Jastrzembski, Associate Professor of History, Minot State University, Minot, ND and Dr. Sara Trechter, Professor of Linguistics at California State University, Chico, CA. I have also initiated an inventory study of plants on the Knife River Indian Villages National Historic Site, Stanton, ND with Dr. Maria Nieves Zedeno, Asst. Research Professor, Bureau of Applied Research in Anthropology, University of Arizona, Tucson, AZ.

I am available as a historical consultant on Mandan and Hidatsa culture for specific topics or periods with professionally prepared essays illustrated with photos.
