Why I'm Running
I am seeking election to Harris County Probate Court No. 4 because I am deeply committed to fairness, integrity, and equal access to justice. With nearly two decades of legal experience, I bring a broad and balanced perspective to the bench. My career includes service as a felony prosecutor, extensive civil trial practice, and appellate experience, with cases handled in both state and federal courts across the country.
I have represented individuals, families, and businesses in complex matters and have also served the courts in trusted roles such as mediator, guardian ad litem, and court-appointed counsel. Through this work, I have seen firsthand the profound impact probate courts have on families, vulnerable individuals, and estates.
Harris County Probate Court No. 4 currently faces a significant case backlog that affects families, wards, and fiduciaries who need timely resolution. If elected, I will bring a disciplined, hands-on approach to docket management, with a focus on efficiency, clear scheduling, and prompt rulings, while never sacrificing fairness or due process.
A probate judge must be knowledgeable, patient, and decisive, and must treat every person who appears before the court with dignity and respect. My experience, work ethic, and commitment to impartial justice prepare me to serve the people of Harris County with competence, fairness, and compassion.
