The company was established in 2002 by Rena Martin, MA-Senior Anthropologist, our mission has been to train, mentor, and support Navajo students in archaeology, cultural anthropology, ethnography, and related fields. The owners and staff collectively have more than 250 years of archaeological, anthropological, and ethnographic experience. None of the senior staff has less than 10 years’ experience; two have nearly 40 years each. The company provides cultural resources compliance services for the Navajo Nation and tribal enterprises and to private and federal contractors for resources evaluations under Sections 106 and 110 of the National Historic Preservation Act.

We have also completed ethnographic studies related to traditional cultural properties (TCPs), ranching, and visual impacts.

As a Navajo company, we have a thorough understanding of Navajo TCPs, and our senior staff members are bilingual in Navajo and English. We gather first-hand information on the identification of culturally sensitive sites as well as unmarked graves (jishchaa’) and work with community members to recommend appropriate management actions.
