About:

I graduated from the University of Georgia in 1973 with honors and continued my education at the UGA School of Law, completing my degree in 1976. I am a co-author of Georgia's leading DUI legal book and have a practice focused on DUI defense litigation. I have received top ratings from Martindale, Best Lawyers, Super Lawyers, and Best Law Firms in America. Since 1978, I have chaired or co-chaired over 50 legal seminars for the Institute of Continuing Legal Education in Georgia (ICLE-GA). In 1991, I co-authored "101 Ways to Avoid a Drunk Driving Conviction" with Reese I. Joye, Jr. Starting in 1992, I also chaired the first annual 2-day seminar, Defense of Drinking Drivers, managed by ICLE-GA. I spoke at the 1992 and 1993 ATLA conventions. In July 1994, I sponsored the first NHTSA training seminar for DUI defense lawyers in Atlanta, certifying 32 attorneys and expert witnesses as SFST practitioners. In October 1994, I organized and sponsored a seminar called "Mastering Scientific Evidence in DUI-DWI Cases." The three-day event featured a mock trial using real jurors. TCDLA now manages this annual multi-day seminar. In 1995, I helped organize and launch the National College for DUI Defense. I also served as a Regent for several years. I self-published "The Georgia DUI Trial Practice Manual" that year. Thomson-Reuters now publishes it. Along with law partners Larry Kohn and Cory Yager, we annually update the book. The nationally acclaimed DWI-DUI lawyer website, DrunkDrivingDefense.com, originated from my first website created back in August of 1996. I organized and financially backed the inaugural four-day NHTSA training seminar for NHTSA instructors the following year. This high-level training helps criminal defense lawyers understand the “pros” and “cons” of police training programs. Our latest two-day GA BAR seminar was held February 27 & 28, 2025.

"Jillian and her team have helped me on and off for years. She always shows up when I need her. I know that all I have to do is call and she will drop what she’s doing to help me. One time my rights were violated and she fought with the crown until my charges were dropped. She’s amazing. Highly recommend her team."
