About Us

Our History

HRA is one of the oldest history and archaeology consulting firms in the United States. In 1974, a small team of historians in Missoula, Montana, began working with federal, state, and private groups to address contemporary legal and administrative problems. By the late 1970s, the firm had expanded its services to cultural resources management and became a leader in providing integrated teams of historians and archaeologists for environmental permitting in the West. We also developed expertise in supporting attorneys with historical research and expert witness work, particularly in the fields of Native American, environmental, and water law.
