Ken Eichner. Veteran advocate and proven litigator, Ken Eichner is one of the top criminal defense attorneys in Colorado with a national name and practice. As a front-lines criminal defense attorney and former prosecutor, Ken launched the Eichner Law Firm in 1996. He defends individuals and corporations in state and federal criminal prosecutions, grand jury inquiries, and regulatory and government investigations in courts across the country. Ken has not lost a federal jury trial against the Department of Justice or any county court jury trial involving domestic violence since 1998. In 2017, he successfully blocked indictments relating to the Clinton email investigation and represented the former Secretary of State’s Denver-based server company at the subsequent congressional hearing. That same year, he also obtained dismissals of sexual assault charges against four individuals. A year later, he represented a witness in the congressional hearing related to allegations against United States Supreme Court Justice Brett Kavanaugh. In 2019, Ken won $2.7 million, the largest verdict in Colorado history in a defamation jury trial stemming from a person of color’s wrongful imprisonment for one night in jail. Having tried over 500 bench trials and 150 jury trials, Ken lends his expertise and sits on the advisory board of LYRIC (Learn Your Rights in the Community), a social justice platform that teaches teens their constitutional rights. LYRIC’s transformative vision: that raising awareness about individual rights will reduce the number of unnecessary arrests and subsequent traumas that often occur.

Ken Eichner defends individuals and companies in often high-stakes, nationally profiled state and federal prosecutions and government investigations. Ken, a former prosecutor, is best known for his courtroom skills and ability to tell each client’s unique story. His practice runs the gamut from a robust county court jury trial docket to defending enforcement actions brought by local prosecutors as well as the Colorado Office of the Attorney General and the U.S. Department of Justice (DOJ). He assists clients to simultaneously handle criminal, civil and regulatory actions that include mortgage fraud, embezzlement, bribery, public corruption, grand jury subpoenas, civil and criminal restraining orders, export controls, sanctions, tax evasion, cannabis licensing, Marijuana Enforcement Division (MED) matters, price fixing/antitrust, drug conspiracies, sex assault, Bitcoin/cryptocurrency, anti-money laundering (AML), domestic violence/violent crimes, Department of Regulatory Affairs (DORA) matters, internal corporate compliance/investigations, national security, and regulatory issues involving the Treasury Department’s Office of Foreign Asset Control (OFAC). 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, Ken pivoted to his true calling as a defense attorney and did county court public defender and federal court-appointed work in Denver. After winning forty plus jury trials that included felony sex assaults and other violent crimes, he was assigned by a federal judge in the 10th Circuit to handle a federal 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 on a ten-defendant insurance fraud case, USA v. Disaster Restoration. Again, Ken’s client was acquitted (along with one other defendant), and the other eight co-defendants plead guilty or were convicted at trial. Eichner Law became the Denver firm that Big Law turns to for local counsel.

Ken mounted a formidable defense and successfully blocked indictments relating to the Clinton email investigation, and represented the former Secretary of State’s Denver-based server company at the subsequent congressional hearing in Washington, D.C. That same year, he also obtained dismissals of sexual assault charges against four Canadian individuals. In 2018 he represented a witness in the congressional hearing related to allegations against United States Supreme Court Justice Brett Kavanaugh. In 2019, the firm won $2.7 million, the largest verdict in Colorado history in a defamation jury trial stemming from a person of color’s wrongful imprisonment for one night in jail. In 2021 Ken was selected by a national law firm to play the role of the federal prosecutor during preparation for the criminal anti-trust jury trial for the price-fixing of chicken, which resulted in acquittals for all defendants. In 2022 Eichner Law helped facilitate dozens of dismissals in county, state, and federal court – including cases involving IRS grand jury investigations, domestic violence cases, gun violations, PPP fraud allegations, and a national security allegation. Having tried over 500 bench trials and 150 jury trials, Ken lends his expertise and devotes time to LYRIC (Learn Your Rights in the Community), a social justice platform that teaches teens their constitutional rights. LYRIC’s transformative vision: that raising awareness about individual rights will reduce the number of unnecessary arrests and subsequent traumas that often occur.
