The Perryman Ranch was established before Oklahoma statehood and is the Creek allotment of Mose S. Perryman, son of Tulsa's "First Family," George and Rachel Perryman.
The ranch contains the 100 year old homestead, the original barn, sweet water well, sandstone root cellar, original sandstone walkway in front of the homestead, and outbuildings. An event pavilion has been added in recent years.
The National Indian Monument and Institute (NIMI) is headquartered at the Perryman Ranch; Robert Trepp is CEO. NIMI is the parent company of the annual Tulsa Indian Art Festival and the American Indian Theatre Company of Oklahoma. It also oversees the American Indian Arts Association.
