The government is a special adversary, with unique powers and vulnerabilities. Sullivan’s Government Investigations & White Collar Defense Group focuses on those crucial matters in which government agencies are our clients' adversaries. At the core of the group is a team of seasoned investigative, trial and appellate attorneys, including former federal prosecutors, other former government attorneys and tax attorneys, who offer substantial experience derived collectively from many hundreds of investigations, regulatory actions and prosecutions. The Group works both on high-profile matters and on those in which a key priority is avoiding publicity.
