On January 1, 2021, Kassius Benson accepted an appointment to be the Chief Public Defender for the Hennepin County Public Defender’s Office in Minneapolis, Minnesota. In this position, Mr. Benson plans to advance an Office that is already one of the best in the country by focusing on training and development of lawyers, national recruiting, and true client-centered representation.

Board Certified and Experienced

The Certified Legal Specialist designation is one way for the public to identify those attorneys who have demonstrated proficiency in their specialty area and to find an attorney whose qualifications match their legal needs. Fewer than 3% of all registered attorneys in Minnesota are certified specialists in their field.

Education and Legal Experience

Mr. Benson graduated from the University of Minnesota Law School.  After law school, Kassius Benson worked at the prestigious Public Defender Service for the District of Columbia in Washington, D.C., where he defended indigent clients charged with serious felony criminal offenses in the District of Columbia Superior Court.   Here, Mr. Benson developed the fearlessness, work ethic, and trial skills necessary to effectively advocate for his clients at every stage of a criminal case.

Mr. Benson eventually returned to Minnesota and, in 2002, he founded Kassius Benson Law, P.A. (formerly Law Offices of Kassius O. Benson, P.A.) with the goal of providing the best criminal defense representation to individuals charged with serious crimes in Federal and state court.

Mr. Benson also trains students and lawyers in criminal defense and trial advocacy.  He is a founding faculty member at the Minnesota Public Defender Trial School and has trained lawyers in Minnesota, Georgia and Alabama.  As an associate professor for clinics, Mr. Benson previously ran the University of Minnesota Law School’s Misdemeanor Defense and Prosecution Clinics.
