Working from the firm’s Washington DC office, the Native American Law group at Dentons boasts a complete advisory and contentious offering and routinely works on the side of tribes across the nation, recently including those in Missouri, Arizona, and Hawaii. Core areas of focus for the group includes representing tribes in claims of tribal sovereignty, land claim settlement issues, and securing full recognition from the federal government. On the advisory front, the team’s capabilities include advising on tribal energy projects, issues involving healthcare and education on reservations, and gaming mandates. Heather Sibbison steers the practice and specializes in matters relating to Native lands, including water rights, non-gaming economic development, and housing. Additional key contacts include Suzanne Schaeffer and Samuel Daughety, who focus on complex Indian lands and environmental compliance issues.
