About David

David O practices criminal defense in Washington, concentrating on DUI cases and related criminal matters. He handles the day-to-day demands of criminal practice. He also appears in court on behalf of people facing misdemeanor and felony charges in state courts across the region.

His path into criminal defense began in the local legal community rather than at a single landmark moment. Over the years he has worked in environments where quick decision-making matters — arraignments, pretrial hearings and emergency motions. Those early demands shaped how he approaches cases now: methodical, practical and attentive to timing.

In courtrooms, David O has represented clients at different stages of prosecution. He prepares for plea negotiations and trials and manages evidentiary challenges when required. He also handles driver’s license hearings and post-conviction matters that often follow a DUI case. He balances courtroom advocacy with casework that happens outside public view, such as evidence review and coordination with investigators.

Clients who consult him usually face immediate legal choices. David O aims to clarify those choices in plain language. He tends to break down complex statutes, explain probable outcomes and outline tactical steps. He also focuses on the procedural milestones that matter—deadlines for filings, timelines for pretrial motions and the implications of plea offers. That practical orientation shapes the way he prepares cases and communicates with clients.

Colleagues describe him as a lawyer who pays attention to the mechanics of criminal procedure. He spends time on witness interviews, document analysis and the technical aspects of DUI evidence. Those details can change the course of a case, and he treats them accordingly. He is equally mindful of the calendar pressures that often drive decisions in criminal matters.

As of 2026, David O is practicing as a DUI and criminal defense lawyer in Washington. He represents individuals facing DUI charges and a variety of criminal accusations in state courts and continues to handle both pretrial work and courtroom appearances.
