We are one of four churches in the Yankton Sioux/Santee Sioux Mission. Woniya Wakan is consolidated from Holy Fellowship from Greenwood, and from Holy Name from Choteau Creek, both in South Dakota. In September of 1989 the grounds were consecrated and eventual construction was completed about 1992. Church services are usually held in English, with hymn singing in Dakota.
Besides being a mission church of the Diocese of South Dakota, we are also a member of the Niobrara Deanery, a group of Dakota, Lakota, and Nakota churches (and some other churches) within the diocese. Niobrara Convocations are held every year, ever since the Episcopal missionaries came to Dakota Territory in the late 1800's. The four churches in the Yankton Sioux/Santee Sioux Episcopal Mission will be hosting the 2014 Niobrara Convocation the last weekend in June at Santee, Nebraska.
