For state and federal criminal defense in downtown San Diego, Bernal Law on B Street brings a former-prosecutor perspective to white-collar fraud, DUI, drug trafficking, domestic violence, and firearm-offense cases in both the San Diego Superior Court and the United States District Court for the Southern District of California. Competency evaluations and mitigation reports in felony sentencing require coordination with behavioral-health clinicians, a defense-preparation step the firm manages through referral networks that include providers such as Areta Crowell Center in the Bankers Hill corridor. Prior service as a Deputy District Attorney in the San Diego DA's Office and as a Special Assistant United States Attorney in the U.S. Attorney's Office, Southern District of California, produced direct trial experience in insurance fraud, healthcare fraud, wire fraud, and tax evasion prosecutions. Digital-evidence preservation and forensic device imaging in federal cybercrime and financial-fraud cases require coordination with IT specialists such as AnytechSD to maintain chain-of-custody integrity under Federal Rules of Evidence standards. The firm also holds an Adjunct Professor appointment at California Western School of Law, where courses in Trial Advocacy and Legal Writing have been taught since 2017.
