Justice Aaron brings extensive experience as a jurist in both the federal and state courts in San Diego. Most recently, she served as an associate justice on the California Court of Appeal for 20 years, resolving all types of cases filed in the Superior Court, including complex civil cases, probate disputes, and family law matters. Because of her extensive appellate experience, she is particularly sought after to conduct post-judgment mediations, assisting parties to assess the risks of pursuing an appeal and weighing those risks against the benefits of reaching a settlement. Justice Aaron has also been retained by appellate practitioners to participate in moot court presentations, to help them prepare for oral arguments.

Prior to her appointment to the Court of Appeal, Justice Aaron served as a U.S. Magistrate Judge in the U.S. District Court for the Southern District of California for over eight years. She conducted hundreds of ENE conferences and settlement conferences in federal civil cases and was lauded by both the bar and the district court bench for her excellent interpersonal skills and exceptional ability to settle even the most contentious cases. The Commission on Judicial Nominees Evaluation described her as an "acclaimed magistrate judge" and a "gifted mediator."

One colleague praised Justice Aaron as a "brilliant and hardworking jurist whose problem-solving skills are invaluable in resolving some of the most complex cases we hear." Justice Aaron applies those same problem-solving skills in assisting parties to arrive at a mutually agreeable resolution to their case, enabling them to avoid the expense, uncertainty, and stress of protracted litigation. She cultivates an atmosphere in which the parties feel free to fully express their concerns and know that they are truly being heard and understood. She is persistent in her approach, believing that reaching a settlement is always in the parties’ best interests.
