Firm Background

Willis Law Firm has practiced DUI defense in Georgia for more than 26 years. The firm’s practice is built around the intersection of constitutional law and forensic science — challenging the state’s evidence at the molecular level by examining breath and blood test procedures, instrument calibration records, field sobriety test administration, chain of custody protocols, and the legal validity of the stop and arrest.

Greg Willis does not simply retain expert witnesses to challenge scientific evidence. He holds the same technical certifications used by law enforcement — including Intoxilyzer operator certification and DRE certification — and has trained as both a student and instructor in standardized field sobriety evaluation. This means he can personally cross-examine the state’s forensic witnesses on equal footing and identify weaknesses that generalist defense attorneys typically cannot.

The firm’s appellate practice is among the most extensive of any DUI defense firm in Georgia. Willis has more than 130 published appellate decisions and has repeatedly shaped DUI law at the state and national level.

Landmark Case: Elliott v. The State

In February 2019, Greg Willis won a landmark ruling at the Supreme Court of Georgia. In Elliott v. The State (Case No. S18A1204, decided February 18, 2019), the court held for the first time that Georgia DUI laws related to breath testing and refusals were unconstitutional. The ruling prohibited prosecutors from using evidence of breath test refusals or breath test numerical results in most pending cases throughout the entire state. The National DUI Defense Lawyers Association recognized Willis with its highest honor, the BadAss Award, for this achievement.

What Sets Willis Law Firm Apart

Unmatched appellate record. With more than 130 published appellate decisions and cases argued before the Georgia Supreme Court and U.S. Supreme Court, Willis Law Firm has shaped DUI law in Georgia more than any other defense firm. Prosecutors reduce or dismiss charges regularly because they know Willis will take a case all the way through the appellate process if necessary.

93.1% success rate, documented over 13 years. More than 93.1% of the firm’s DUI cases over the past 13 years have been resolved without a DUI conviction. This is a firm-tracked metric based on actual case outcomes.

Technical credentials that match law enforcement. Greg Willis holds the same technical certifications as the officers and analysts who generate the evidence against his clients — Intoxilyzer operator certification, DRE certification, and SFST instructor-level training. This allows him to challenge that evidence from the inside.

National leadership in DUI defense. As President of the DUI Defense Lawyers Association (DUIDLA) and a Founding Member of the organization, Greg Willis is not only practicing at the cutting edge of DUI defense — he is helping set the standard for the national DUI defense community. Other attorneys pay to attend his seminars to learn his strategies.

Willingness to fight at any cost. In a case where a judge refused to postpone trial until a key witness could appear, Willis chose to spend four days in jail for contempt of court rather than abandon his client’s right to that testimony. He returned with the witness and won.
