Dedicated to Representing Native American Interests

Sonosky, Chambers, Sachse, Endreson & Perry, LLP is a national law firm devoted to representing Native American interests in a wide range of endeavors including trial and appellate litigation, federal Indian law, tribal law, Indian self-determination and self-governance matters, health law, commercial and corporate law, tax law, land claims, natural resources law, public land law, water law, land regulation, hunting and fishing rights, environmental law, toxic torts, jurisdictional conflicts, gaming law, government contracting, hydroelectric development and business development.

The firm's practice includes representation of tribal interests in federal, tribal and state courts, and before Congress, state legislatures and federal and state agencies. We also regularly appear before congressional committees, sometimes as expert witnesses by committee invitation. Members of the firm have also briefed and/or argued more than a score of cases in the United States Supreme Court.

Typical of the firm's clients are tribal governments, Alaskan Native corporations, Native American-owned health corporations, regional tribal confederations and Native American health and social service providers. The tribes and Alaskan Native entities we represent range from the very smallest to the second largest tribe in the nation, and they are situated throughout the United States. We do not represent non-tribal interests - such as gaming management companies or oil and gas developers - on Indian law matters.

The firm also has an active election law practice and has served as counsel to a major national reform organization, working in Congress, the courts and administrative agencies, to craft and defend major reforms to the nation's campaign finance laws.

The firm has twenty-seven lawyers based in five offices in Washington, D.C., Albuquerque, San Diego, Anchorage and Juneau. The firm was founded in 1976 when Reid Peyton Chambers and Harry R. Sachse left positions as Associate Solicitor for the Department of the Interior and Assistant to the Solicitor General of the United States Department of Justice, respectively, to join Marvin J. Sonosky, long recognized as one of the nation's leading practitioners of Indian, public lands, minerals and natural resources law. Mr. Sonosky practiced actively with the firm until his death in July 1997. Together our lawyers have extensive and wide-ranging experience in Indian law, and we have handled virtually every kind of matter arising across the broad spectrum of tribal legal needs.
