Legal Experience

In describing her work on family violence initiatives, Diaz said: “Through my work on family violence initiatives and trauma-informed practices, I helped develop cutting-edge approaches that prioritize safety, responsibility, and meaningful behavior change, like the Civil Family Violence Prevention Program (FVPP). I utilize FVPP to increase compliance with orders, including firearm prohibitions, by providing processes and staff to follow up on compliance in a previously nonexistent manner.”

Judicial Administration

Question: “Philosophically, how do you balance the public’s desire for restitution in all types of crimes, while also providing a productive path forward for offenders who don’t pose a danger to the public?” Diaz answered: “Although I am a civil district court judge and do not preside over criminal cases, the principles of accountability, fairness, and rehabilitation guide my work every day, and they are not mutually exclusive. In civil matters, particularly those involving families, family violence, and vulnerable individuals, I focus on holding parties accountable while ordering solutions that promote healing, long-term stability, and compliance.”

In her response on balancing accountability and a productive path forward, Diaz described family-violence and trauma-informed practices, then concluded: “Our system works best when judges uphold the rule of law while also addressing underlying issues that bring people into court, expectantly reducing recidivism.”
