The Tulalip Tribes was organized under the Indian Reorganization Act of 1934. Tulalips' Constitution and Bylaws were approved January 24, 1936 and a Charter ratified October 3, 1936. The governing body is the seven member Tulalip board of directors. As of April 19, 2004 the Tribe had 3,611 members live and active on the reservation. The Tribe provides many services to its members including preschool, higher education assistance, health and dental clinics, a pharmacy, a state-licensed chemical dependency recovery program, senior retirement home and cultural activities. The Tulalip Tribes provides over-sight to the Tulalip Housing Authority, which provides nearly 300 housing units for Tribal members, and to the Tulalip Utilities District, the primary provider of water/sewer services. Of the 1,200 employees working for Tulalip Tribes over two-thirds are working in the Tribe's business enterprises: Casino/Bingo, land leasing, cablevision company, marine moorage, liquor store and the Quil Ceda Village Business Park.
