Hon. Susan Lopez-Giss (Ret.) served 15 years as a Judge for the Los Angeles Superior Court, with the entirety of her time on the bench devoted to Family Law. Judge Lopez-Giss presided over thousands of cases involving all types of contested and complex Family Law matters, including parentage cases, custody and visitation issues, child and spousal support, business valuation, and property division. In addition to issuing thousands of rulings, Judge Lopez-Giss became known for actively and successfully settling her cases. Her strong legal mind, coupled with an emphasis on collaboration to resolve family disputes, has resulted in her reputation as an effective problem solver and adjudicator.

Prior to her judicial career, Judge Lopez-Giss served 30 years in the Los Angeles City Attorney’s Office, where she developed a groundbreaking domestic violence prosecution program that was implemented statewide, only one of such programs in the country at the time. She was instrumental in drafting a domestic violence prosecution manual, filing guidelines, and restraining order statutes, and helped train law enforcement and medical personnel across the country. Judge Lopez-Giss also developed guidelines for the handling of child abuse and child sexual abuse and served on interagency councils that addressed child abuse and neglect that included training for mandatory reporting. She also reviewed and personally oversaw the prosecution of hundreds of such cases. For her pioneering work developing these programs, Judge Lopez-Giss was presented with a Resolution by the Mayor and the Los Angeles City Council.

Judge Lopez-Giss later became the City Attorney’s Assistant General Counsel for the legal division of the Department of Water and Power. She holds the distinction of being the first woman to reach that position. In this role, Judge Lopez-Giss represented LADWP in matters involving employment, contracts, regulatory matters as mandated by the Federal Energy Commission, the California Public Utility Code, water issues, rate structures, tort, workers’ compensation, and environmental issues.

“By far, the best mediation experience I have had in a long time. Thanks for being a rock star.”

“Excellent neutral. I will recommend her as much as possible. Will use her again.”

“Judge Susan Lopez-Giss recently settled a very contentious case for our client involving high conflict parents, domestic violence allegations and custody issues at a crisis level with three children. Counsel on the opposing side is esteemed in the community, but the potential for settlement seemed non-existent. Nevertheless, Judge Lopez-Giss assisted the parties and counsel so that after three sessions a resolution was reached. The Judge was firm with the parties but allowed them to be heard. She was well prepared and worked diligently including extra phone call conferences to allow counsel to brainstorm. I recommend her for high conflict cases.”
