Judges and Staff


Judge Michael R. Montero was born October 13, 1966, in Winnemucca, Nevada, and spent his childhood on the family ranch in rural Humboldt County. He graduated from Albert M. Lowry High School in 1984, and thereafter received a Bachelor of Science degree in Agriculture and Resource Economics from Oregon State University in Corvallis, Oregon. He went on to earn his law degree from Washburn University School of Law in Topeka, Kansas.

After completing law school, Judge Montero began practicing law in Reno, Nevada, with the law firm of Lemons, Grundy & Eisenberg. While at Lemons, Grundy & Eisenberg, Judge Montero’s practice focused primarily on litigating the defense of claims involving personal injuries stemming from automobile and aviation accidents, premises liability, and products liability. His practice also included representing insurance companies in first-party claims, and advising insurance companies on coverage and valuation issues. In 2006, Judge Montero joined the Echeverria Law Office, a firm that specializes in representing the catastrophically injured in plaintiffs’ personal injury litigation throughout the western United States, primarily in Nevada and California.

In November 2008, Judge Montero was elected as District Judge in the Sixth Judicial District Court, Department II. In addition to his judicial duties within this district, Judge Montero currently chairs the North Central Region Judicial Council and serves as a representative on the Judicial Council of the State of Nevada. Furthermore, Judge Montero is a Nevada delegate to National Conference of State Trial Judges of the American Bar Association, serves on the Nevada Children’s Justice Act Taskforce, and is a member of the Administrative Office of the Court’s Leadership Summit Planning Committee.

Since the Sixth Judicial District was split by the Nevada Legislature on July 1, 2015, Judge Montero is the only judge presiding over the Sixth Judicial District of Nevada. His caseload is now comprised of every civil and criminal case that originates in or proceeds to the District Court level in Humboldt County.
