Los Angeles County Superior Court, Department retired

Appointed By: Gov. Arnold A. Schwarzenegger

Biography

Overview

The Hon. Kathleen O. Diesman (Ret.) was a judge for the Los Angeles County Superior Court in California. Diesman was appointed to the bench by former Governor Arnold Schwarzenegger in January 2008, filling the vacancy created by the retirement of the Hon. Charles L. Peven[1]. She retired in January 2017[2].

While on the bench, her assignments included criminal, limited civil, and family law matters[1]. Her first permanent assignment was in West Covina, beginning in April 2008[1]. Before retirement, she served in a family law department at the Stanley Mosk Courthouse[1].

Educational background

Diesman earned a B.S. from the University of Toronto in 1976. She later completed a master's degree at the University of Toronto[1]. Following those studies, she taught in Toronto schools before entering law school[1]. At DePaul University College of Law, she completed a J.D. in 1983. She was admitted to the State Bar of California (December 11, 1986)[3].

Career history

After graduating from law school, Diesman entered private practice at a large insurance defense firm in Chicago. She later continued in private practice in Los Angeles[1]. In 1990, she joined the Los Angeles County District Attorney's Office as a deputy district attorney. During that tenure, her work included child abuse prosecutions and, later, Proposition 36 matters[1].

Her court committee service included the Judicial Education Cross-Over Committee, the Community Outreach Committee, the Power Lunch Committee, and the Civil & Small Claims Committee of the Los Angeles County Superior Court.

Personal life

Born and raised in Chicago, Illinois, Diesman made Los Angeles her home after a temporary assignment with her law firm[1]. Her move into prosecution followed limited trial opportunities in civil practice[1].

Diesman is registered as a Democrat[1].
