Your Journey with ETD, Inc.: Our Story, Your Success

In the heart of Northern Arizona, where Native American communities are woven into the very fabric of the landscape, ETD, Inc. was born. Surrounded by these vibrant communities, we recognized the unique challenges they faced in navigating tribal land development.We were founded on the belief that every tribal community deserves a bright future—one shaped by adequate housing, public facilities, infrastructure, and economic development that exist in harmony with the natural environment.

Our journey began in 1995 as Environmental Technology Development (ETD), a beacon of hope for project developers on tribal lands. Initially focusing on environmental compliance, over the years we’ve evolved to meet the growing needs of tribal communities. Today, we provide complementary services including project management, public relations, natural resource planning, and strategic planning, and stand as an award-winning professional services firm.
