Criminal defense and record-clearing services in downtown San Diego's Gaslamp Quarter are the exclusive focus of the Law Office of Isaac Blumberg on Broadway, a practice built on former San Diego County Deputy Public Defender trial experience dating to 2004. DUI and vehicular-crime cases frequently involve vehicle-damage evidence, and the firm coordinates independent mechanical assessments through facilities including Downtown San Diego Auto Repair to document impact severity for defense-theory development. An Emory University School of Law Juris Doctor, Super Lawyers selections from 2023 through 2026, and an Of Counsel role with the Kavinoky Law Firm since 2008 support a caseload spanning DUI, drug crimes, assault, robbery, murder, identity theft, domestic violence, vehicular manslaughter, and expungements under Penal Code Section 1203.4. Bilingual English-Spanish intake reflects the firm's service to San Diego's cross-border community, with nearly 30 criminal jury trials completed across Southern California courthouses. Defendants in DUI-injury cases involving concurrent physical harm require medical documentation, and injury records are coordinated through providers such as Bayside Spine & Sport for soft-tissue and spinal assessment. The most complex matters involve felony-to-misdemeanor reduction petitions under Proposition 47 and Penal Code Section 1170.18, requiring detailed analysis of prior conviction records, current offense classifications, and restitution-balance documentation.
