Oliverson Law DUI & Criminal Defense fights for clients across Arizona — DUI, drug, assault, domestic violence, weapons, and felony charges. Founded in 2009 by a former judge, prosecutor, and police officer.
Founded in 2009, Oliverson Law DUI & Criminal Defense represents people facing the hardest moment of their lives — a DUI, a felony charge, a domestic violence allegation, a drug case, a weapons charge.
What sets this firm apart is the team behind every case: a former judge, a former prosecutor, and a former police officer. Each of those roles teaches you something the other side knows — and we use all of it to defend you.
Over 17 years, the Oliverson team has handled 5,000+ criminal and DUI cases across Arizona — from Maricopa County to Apache County, from Tempe Municipal Court to the appellate division. We know the courtrooms, the prosecutors, and the procedures.
And we keep the work close: the same lawyer who answers your call is the lawyer who walks into court with you. No bait-and-switch, no junior associates running the show.
Results earned in Arizona courtrooms — not marketing claims.
Unlike solo practitioners, Oliverson Law brings a team of former judges, prosecutors, and police officers to your defense.
