Gary Jackson | Judge Denver County Courtroom 3F

jackson Lindsey-Flanigan Courthouse 3rd Floor

Gary Jackson is a judge on the Denver County Court in Colorado. He was appointed in January 2013 and will need to run for retention in 2016.


Jackson received a bachelor's degree from the University of Colorado in 1967, and a J.D. from the University of Colorado School of Law in 1970.

During his third year at Colorado Law, Jackson interned in the appellate division of the Denver district attorney’s office, and was hired full-time after he finished law school. During his first year with the district attorney’s office, Jackson spent his time in the county court handling misdemeanors. He was appointed chief trial deputy over the juvenile court in his second year, and thereafter spent two years as the trial deputy in the felony division. Then in 1974, after four years with the district attorney’s office, Jackson was hired by the U.S. attorney’s office in Denver, where he went to work in the civil division. In this role, Jackson worked on a wide array of issues, including medical malpractice, land condemnation, personal injury, and civil rights cases.

Jackson left the U.S. attorney’s office in 1976 to found the firm of DiManna, Eklund, Ciancio & Jackson, which became DiManna & Jackson in 1981. Jackson’s specialization shifted several times over the course of his 37 years in private practice. After starting off doing mostly criminal defense work, he began to focus more on personal injury matters. Then, when the savings and loan banking crisis hit during the 1980’s, Jackson’s firm was one of a few small firms hired to do FDIC and RTC work for the government. This work kept Jackson busy for roughly six years, and eventually led to him being hired by the Denver Baseball District as the trial attorney for the acquisition of the land upon which Coors Field stands. In the few years immediately preceding his appointment to the bench on the Denver County Court, Jackson represented lawyers and judges who were facing charges of misconduct. Jackson became “Judge Jackson” in January of 2013, returning to public service and bringing his legal career full circle.
