Richard Twiss

Quite an interesting story and journey this man has.  Here's what was written about him on Wikipedia:

Richard Twiss is a Native American educator and author. He is a member of the Rosebud Lakota Sioux Tribe from South Dakota. He is the Co-Founder and President of Wiconi International (Wee-choe'-nee is Lakota/Sioux for "life") .

In 1972, Twiss was a participant in the forced occupation of the Bureau of Indian Affairs Building in Washington, D.C., with the radical political group, the American Indian Movement or "AIM." Twiss later became a Christian minister, author, and public speaker.

His vision is, "To serve the Church as a bridge builder and consulting resource to see Native people come to faith and life in Jesus Christ and fulfill their God-given place in the Body of Christ."
