Tanya Johnson Martinez

Tanya Johnson Martinez is a Fargo, North Dakota criminal defense attorney and the owner of Martinez Law, PLLC. She represents people accused of state and federal crimes, including homicide, drug offenses, and complex white-collar charges. Her practice also addresses DUI matters, expungements, post-conviction relief, and restoration of firearm rights. She brings prior prosecutorial experience to the defense of individuals whose rights and freedom are at stake.

Tanya attended the University of North Dakota School of Law and was admitted to the North Dakota bar in 2003. Her legal training was followed by extensive work as a prosecutor before she moved into criminal defense. That background gives her direct experience with how criminal charges are evaluated and pursued, the role of evidence in a prosecution, and the legal standards that apply when the state seeks a conviction.

Tanya spent 14 years as a career prosecutor and handled matters ranging from traffic offenses to serious felony cases. She served on the prosecution team in the Savannah Greywind murder case and prosecuted those responsible for the killing of Fargo food truck owner Jason “Jay” Halvorson. Her experience in complex prosecutions informs her work assessing the evidence, anticipating arguments, and preparing defenses in difficult criminal cases.

Tanya Johnson Martinez now applies that courtroom background to protecting the constitutional rights of accused people. She emphasizes candid communication, due process, and an informed understanding of the options available in a criminal case. By considering the case from both prosecution and defense perspectives, she helps clients address serious allegations and navigate decisions that may have lasting effects.
