Derek Oliverson spent years on the other side — as a police officer, prosecutor, and judge. Now he uses that experience to dismantle the prosecution’s case and defend your future.

Derek Oliverson founded Oliverson Law in 2009 with a single mission: give people facing criminal charges the same aggressive, tactical defense that was once used against them.
Before becoming a defense attorney, Derek served as a police officer, prosecutor, and judge. That rare combination means he’s sat in every chair in the courtroom — and he knows exactly how the other side thinks, builds cases, and makes decisions.
Over 17 years, Derek has personally handled more than 5,000 criminal and DUI cases across Arizona. He knows the prosecutors in Maricopa County, the judges in Tempe Municipal Court, and the procedures in every jurisdiction from Phoenix to Kingman.
Derek doesn’t hand your case to a junior associate. He answers his own phone. He returns calls the same day. And he fights like your future depends on it — because it does.
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.
