About Us

Rathburn Law Office, P.C. handles the defense of Operating While Intoxicated (OWI/DUI) cases and complex traffic matters in Indianapolis and Central Indiana. Our practice focuses on cases where science, testing procedures, and regulatory compliance have a significant impact on the outcome.

Unlike firms that treat DUI defense cases as routine criminal matters, our firm is built around technical mastery of the evidence used in these prosecutions. Chemical testing, breath analysis, and standardized field sobriety testing are central to nearly every OWI case.

Our approach is grounded in a detailed understanding of how this evidence is generated, how it is supposed to function, and how errors in testing or procedure can undermine the prosecution’s case.
