About me

I live in Augusta, Georgia.  I have a grown daughter who is a school teacher in south Georgia, and my son is a bankruptcy lawyer here in Augusta.  Some years ago I decided to focus on DUI defense, as I saw that many DUIs could be beaten or reduced by working the case hard and knowing DUI law inside and out.  DUIs are very complicated, and it is an area in which I devote an overwhelming majority of my time as a defense lawyer. My staff and I work each case hard and look for every opportunity to get the case either dismissed or reduced. Additionally, we take cases to jury trial.  The prosecutors know that we are not just negotiators or pleaders; that we will not stop short of a jury trial if we cannot get the desired result and our client wants a trial.  I am a member of an exclusive, invitation only Georgia DUI membership organization which has only around ninety members statewide.  At Duncan Law Firm LLC we constantly try to stay on the cutting edge of DUI defense techniques, and our results for our clients speak for themselves. Take a look at our website ( to see some recent results.  For hard work and fast action, call me today.
