About me

Mr. Willingham received his Bachelor of Business Administration in Business Economics from Georgia State University.  He received his Juris Doctor from Atlanta's John Marshall Law School, where the faculty conferred upon him the Harold R. Banke Advocacy Award, given every year to the graduate who best evidences the potential to develop into an accomplished litigator.  He also served as captain of the Mock Trial team and has since returned to serve as an adjunct professor  in trial advocacy.  


As a trial lawyer, Mr. Willingham has enjoyed a very successful track record. He began his career with the renowned Marietta firm of Leonard, Rickman & Holloway, P.C., whose lead partner has since been appointed to the bench of Cobb County Superior Court.  It was there that he learned the skills to be a successful criminal litigator, focusing primarily on DUI defense.  At a young age, David successfully obtained several "not guilty" DUI verdicts in a row, drawing the attention of lawyers and judges in Cobb County.  In 2011, Mr. Willingham was recruited by the Cobb County District Attorney's office to serve his community.  David answered that call and gained invaluable experience prosecuting and trying before juries every type of felony offense in Cobb County, including murder, armed robbery and complex financial fraud cases.  

Mr. Willingham is NHTSA trained in field sobriety evaluations.  He is trained on the Intoxliyzer 5000 and strives to stay on the cutting edge of law and technology.

  • Kenneth Peter Crosson

    David has a reputation that lawyers with a lot more grey hair would envy, and he earned it the right way, aggressively defending his clients, beating charges, and winning tough trials. I have referred a number of clients to him and will continue to do so. If I ever found myself on the wrong side of criminal charges, I would call on him myself without hesitation.
