Kenneth Eichner, a former prosecutor, is best known for his courtroom skills and ability to tell each client’s unique story. He has tried over 150 jury trials to verdict and has secured a string of significant verdicts for his clients in state and federal court. His practice runs the gamut from a robust county and state court jury trial docket to defending enforcement actions brought by the Colorado Office of the Attorney General and the U.S. Department of Justice. He assists clients to simultaneously handle criminal, civil and regulatory actions that include fraud, embezzlement, bribery, public corruption, grand jury subpoenas, civil and criminal restraining orders, tax evasion, cannabis litigation, price fixing/antitrust, drug conspiracies, sex assault, money laundering, domestic violence/violent crimes, Department of Regulatory Affairs matters, internal corporate investigations, and national security issues. His practice also includes selective civil rights actions to address governmental abuses of power.

After trying over a hundred jury trials, including prosecuting a notorious school shooting that garnered national attention, Kenneth pivoted to his true calling as a defense attorney and did state and federal court-appointed work. After winning forty plus jury trials that included felony sex assaults and other violent crimes, he was assigned by a federal judge to handle a bombing case, USA v. Jon Williams, that involved six co-defendants. Williams was acquitted of all charges and the other co-conspirators were sentenced to life in prison. The federal court then appointed him to a ten-defendant insurance fraud case, USA v. Disaster Restoration. Again, Ken’s client was acquitted of all charges and the co-defendants plead guilty or were convicted at trial.

Other notable victories are as follows. Kenneth mounted a formidable defense against the F.B.I., obtained full immunity for his client, and successfully blocked indictments relating to the Clinton email investigation. He represented the former Secretary of State’s Denver-based server company at the congressional hearing in Washington, D.C. He also obtained dismissals of sexual assault charges against four Canadian individuals. Kenneth represented a witness in the congressional hearing related to allegations against United States Supreme Court Justice Brett Kavanaugh. In 2020, the firm won $2.7 million, the largest verdict in Colorado history in a defamation/malicious prosecution jury trial stemming from a person of color’s wrongful imprisonment for one night in jail. Eichner Law was local counsel for an executive in a multi-billion dollar company in a federal criminal action alleging price-fixing in the chicken industry, which resulted in acquittals for all defendants. In 2026 Kenneth’s litigation team helped facilitate dozens of dismissals in county, state, and federal court – including cases involving IRS grand jury investigations, domestic violence, gun violations, fraud charges, and a national security allegation. Kenneth lectures at the University of Colorado Law School’s criminal defense clinic in trial strategy, jury selection, opening and closing argument presentation.
