Why Oliverson Law Is Different
Most criminal defense attorneys have only seen cases from one side. Derek Oliverson has seen them from every side. As a police officer, he made the arrests. As a prosecutor, he filed the charges. As a judge, he decided the cases. Now, as a defense attorney, he uses all of that experience to protect your rights. This perspective allows our team to anticipate the prosecution’s strategy, identify weaknesses in their case, and build defenses that work in the real world — not just on paper.
