Joseph P. St. Louis takes over as dean of National College for DUI Defense

Arizona DUI defense lawyer Joseph P. St. Louis has started a one-year term as dean of the National College for DUI Defense, where he will oversee advanced training for attorneys handling cases built around forensic science and constitutional issues.

Why it matters: - Advanced DUI defense now depends heavily on scientific evidence, including breath-testing, blood-testing, toxicology and pharmacology. - NCDD trains more than 1,700 attorneys across the United States and Canada, so the dean’s priorities can shape a wide legal education network. - Expanded access to advanced training matters for both large law firms and under-resourced public defender offices.
