For the past 26 years Mark Geller has been a prosecutor with the Orange County District Attorney’s Office, retiring in January 2022 as a Senior Deputy DA. As a prosecutor Mr. Geller completed close to 150 jury trials for crimes including Domestic Violence, Sexual Assault, and Gang Homicide, to name a few. Twice he was chosen prosecutor of the year by his peers and received many accolades throughout his distinguished career including awards from Mother Against Drunk Drivers and CSP (a victim’s advocate group). For the last 6 years he has worked as the sole Domestic Violence (DV) felony prosecutor for all of South Orange County stretching from Irvine to San Clemente. While he has developed relationships with every police agency in the County, his recent focus on DV leaves him uniquely situated to assist both victims and those accused with navigating the complex criminal justice system associated with Domestic Violence. His vast experience and very recent intimate knowledge of the inner workings of the DA’s office provide any potential client with the certainty that their case will be handled in the most beneficial way to ensure the best possible result.
