Former United States attorney and Colorado deputy attorney general. Seasoned counselor and litigator for clients facing federal and state government investigations and internal investigations. Recognized political law advisor to corporations and nonprofits on campaign finance, election and ballot initiative law.

Throughout his time as United States attorney, deputy attorney general of Colorado and years of private practice, Jason Dunn has handled some of the highest-profile cases in Colorado. As the top federal law enforcement official in Colorado, Jason led an office of 200 attorneys and staff prosecuting high-profile criminal and civil matters on behalf of the United States.
