About me

Ms. Grimes attended the University California at Irvine and majored in Social Ecology with a special emphasis in Criminal Justice. Since her first year of college, she has been focused on a career in law. While in college, she received a research grant to study domestic violence cases. This research focused on the responses of victims to domestic violence and the interplay with police departments and the district attorney’s office. She also spent a summer working as an intern on Capitol Hill in Washington, D.C. After college, Ms. Grimes attended Loyola Law School in Los Angeles where she earned her Juris Doctor degree. During her three years of law school, she was able to intern with both the Los Angeles District Attorney’s office and the Organized Crime Unit of the United State Attorney’s Office. She also had the honor of clerking for the Los Angeles Superior Court and was selected to serve as a staff member on the International and Comparative Law Journal. Ms. Grimes also worked as a summer intern for the Orange County District Attorney’s Office.


In 1991, Ms. Grimes was sworn in as an Orange County Deputy District Attorney. She worked as an OC Prosecutor from 1991 until 1998. Her first assignment in the District Attorney’s Office was in the Child Support Unit. This assignment entailed frequent appearances at the family law courthouse negotiating cases and conducting hearings. While at the District Attorney’s Office, she also prosecuted many types of cases, ranging from misdemeanors to felonies, and served as vice-president of the Association of Orange County Deputy District Attorneys. When she left the office, she was the Hate Crimes Deputy, filing and prosecuting hate crimes and also prosecuting cases involving public officials and police officers. In 1998, Ms. Grimes moved to Santa Barbara where she continued her prosecutorial career. She became a Deputy District Attorney in Ventura County. She later worked as a Deputy County Counsel with the Santa Barbara County Counsel’s Office. While with the County Counsel’s Office, she handled enforcement issues, civil litigation defending the county, and advised county agencies on employment law. Part of her duties included advising the County Supervisors in confidential meetings.
