Sustainable economic development, especially through tribally-owned business enterprises, has become a central emphasis for most federally-recognized Native American tribes, as they generate the revenue needed to provide opportunities and services for tribal members. Because of their nature, these enterprises are affected by various economic, governmental, legal, and cultural factors. Barber & Bartz has the collective knowledge and skill, developed over years of experience in working with tribes, to help organize and structure efficient and effective tribal business entities, and to create an environment in which their enterprises can grow, while at the same time honoring the history, traditions, and culture of particular nations, and guarding their sovereign immunity which is so critical. We have also worked directly with executive and legislative branches of governments on matters such as interpretation and application of tribal laws and constitutions and relations with state and federal regulatory agencies. Our goal is the success of tribal enterprises for the ultimate benefit of the citizens of the nation.
