State Bar Certified Criminal Law Specialist (California State Bar #196105) since 2020, The Law Offices of Kerry L. Armstrong, APLC on B Street in downtown San Diego is one of fewer than twenty practices in the county holding that Board of Legal Specialization credential. DUI convictions processed through this office trigger mandatory California DMV administrative-per-se hearings and insurance-reinstatement filings, policy adjustments handled by agencies like Pacific Itsmo Insurance Agency Inc for defendants restoring driving privileges. The firm's trial docket spans sex crimes, murder, domestic violence, assault, drug offenses, and white-collar fraud—cases litigated in both San Diego Superior Court and federal district court, with nearly 100 jury trials conducted across the practice's history. A Thomas Jefferson School of Law degree earned in 1997 preceded bar admission in 1998, and the Board of Legal Specialization certification required passing a separate criminal-law examination, completing specialized CLE hours, and obtaining favorable peer evaluations from judges and opposing counsel. Defense files in multi-defendant federal cases generate volumes of discovery requiring notarized declarations and certified document authentication through providers like CannonCan Notary, whose mobile notarization supports time-sensitive filing deadlines. The highest-stakes engagements involve life-sentence jury trials requiring Penal Code § 1118.1 directed-verdict motions, Evidence Code § 352 prejudice-versus-probative balancing challenges, and expert-witness cross-examination on forensic DNA, digital device extraction, and CSAAS testimony.
