Highly Recommend!

Gillian has been with me every step of the way through a long, difficult divorce and custody case. She has worked tirelessly to ensure a successful outcome in my case and has made a very stressful time more bearable; keeping me informed and helping me understand this process by answering all my ques...tions and addressing my concerns along the way. She has always been accessible, professional and made me feel not only expertly represented but cared for as well. I would (and have) highly recommend Gillian.

Outstanding Divorce Lawyer

There aren't enough adjectives to describe how impressed I have been with Gillian O’Nan. I found her on AVVO after mediation failed to resolve all the outstanding issues in my divorce and my case was dragging on with no end in sight. Gillian quickly stepped in and was able to absorb all the backgroun...d and nuances of my case in a short period of time. She is very professional, intelligent, upfront, honest, and to the point. Gillian did a great job of keeping me level headed in unarguably the most emotionally trying time an individual can go through, while taking my concerns into consideration. What made my case unique was that I reside in Texas, but was going through a divorce in Atlanta. However, from the moment I talked with Gillian, I had the utmost confidence that I had made the right decision in retaining her. She worked tirelessly on my behalf, leveraging her sound knowledge of the law to bring my tricky case to a quick close, even though opposing counsel was not very cooperative. If your case ends up in the courtroom, you can rest assured that you’re in good hands. Gillian is quick witted, tenacious, and a very good litigator. One of the many qualities that sets Gillian apart is her responsiveness. She is extremely accessible and does a great job of staying in touch with you and answering your questions. With her you never have to worry about being forgotten about and because she is proactive, you will always feel like you’re her number one priority. If you are ever in need of a divorce lawyer, you will be hard pressed to find a better advocate for you than Gillian O’Nan. Thank you Gillian!

Is there any way to add an extra star?!

I can't imagine how difficult it would have been having to deal with my ex-wife and her aggravating lawyer without Gillian's help. From the first phone call, to the consultation...to the final decree and closing letter, Gillian always kept me informed and I was never made to feel like she was busy ...with other people or other things. I felt very confident that my case wasn't buried under a mound of paperwork on a disorganized desk and was being attentively looked after. 50% of all lawyers graduate in the bottom half of their class. My ex-wife's lawyer was probably one of them. Gillian isn't. She takes herself and her profession seriously and I would highly, highly recommend her to anyone that wants straightforward and serious legal representation. Thanks again Gillian!

Guiding Me Through a Difficult Time

I came to Gillian through a friend's referral. I was beginning the process of divorcing my husband of 11 years and was in a emotionally fragile state. She very professionally guided me through the process with compassion but stayed detached enough to keep me focused on what I needed to do. A divo...rce I thought would take forever to complete was done in 4 months. I have already referred Gillian to others and will continue to use her for future legal counsel.

ABOVE and FAR BEYOND!!!!!!!

Ms. O'Nan was one of the attorneys assigned to my child custody modification case a few years ago. Before that, I did not know her at all. Though the outcome of that case was the worst news that I have received during my lifetime and handled very poorly by the lead attorney on my case, Gillian is the... only reason that I was able to keep my composure at that time and to this day. Gillian has remained close to me and my daughter while we weather the unfortunate outcome we were faced with when my daughter was only ten years old. Gillian cuts right to the heart of the most heartfelt matters with kindness, passion and genuine concern. I have and will only recommend her to anyone in need of a "real person" to represent them in family law matters. My wish is that you are not dealing with court at all. If you must, Gillian is the person for the job.

"Gillian is the archetype of the kind of attorney that makes children want to grow up to be attorneys. She is ethical, uniquely capable, brilliant, compassionate, and wise. I would not hesitate to send a member of my own family (if God forbid anyone needed a family lawyer) to Gillian. To the extent the law is still regarded as an admirable profession, it is because lawyers like Gillian exist."
