Top Notch!

Gillian has represented people that I know and myself and I can only say that she is very diligent and aggressive in representing her clients. Gillian is easily accessible and has always returned my calls promptly. I cannot be more pleased with the outcome of my case as she was very well prepared a...nd refused to give any wiggle room to the opposing attorney. Her fees are reasonable and her intent was always to contain the legal expenses to a minimum. I will never hesitate to use Gillian in the future and will highly recommend her to anyone looking for a top notch attorney.

The best there is

Gillian is the consummate professional. From the beginning of our case, she was honest and upfront about possible obstacles and worked on a strategy that was in our family's best interest. She kept us updated throughout the process, advised us well, and we always felt that she had our backs. I cannot... recommend Gillian highly enough!

Highly recommended

Gillian was recommended to me at the beginning of what became a very long, ugly process due to the actions of my ex and his attorney. Gillian was always responsive, explained things thoroughly and helped guide me through a very painful and complicated situation. Again and again, she told us what she ...expected the outcome to be at different points and she was proven to be correct each time. She was a strong advocate for both myself and my children and I completely believe that we owe our successful outcome to her. I've recommended her to several people since and would not hesitate to do so in the future.

Superior expertise, tenacity, and ethical values are evident qualities Gillian O'Nan's clients can expect

I was referred to Gillian O’Nan to represent my custody, visitation, and child support modification case of my 3-year-old child in 2014. Upon my initial consultation, I was thoroughly impressed with Ms. O’Nan for several reasons. She listened intently to the history surrounding my case, concerns rega...rding my daughter, and reviewed the supporting evidence I provided to substantiate my claims. Gillian explained in depth the family laws in Georgia and identified the pertinent facts warranting the initiation of my case in Superior Court. Throughout the 32 months of my contested custody case, from initiation to the final hearing, Gillian never ceased to advocate for me and my child every step of the way! She exhibited the upmost professionalism in all correspondences and in the courtroom at each hearing. This was particularly evidenced in the seven-hour long temporary hearing where she presented the facts and remained focused, which resulted in me obtaining full physical custody on a temporary basis. Gillian continued to represent me in the highest regard over the next two years and kept me abreast on important updates and information in a timely manner. Ultimately, the temporary order was upheld and I am now the primary physical custodian. I know the outcome of my case would not have resulted in the same success if I hired a different attorney to represent me back in 2014. I entrust Gillian’s expertise for not only matters pertaining to me but to all my family and friends as well.

Amazing Attorney!

Gillian is an excellent attorney! I've worked with 3 different lawyers for the same divorce/custody case and then currently a parenting time modification case, all over a span of 10 years. Gillian came on board recently, closer to the trial but she showed incredible expertise not just in legal knowle...dge but also being able to go through years of history & getting out just the points that was relevant for the current case and got me positive results. She is honest, intelligent, extremely efficient and very responsive (which I've never had with my previous attorneys). You know that when you ask her a question or something that needs to be done she will get to it immediately or if she is not available right away, you can still trust her to get it done as soon as she is available and without needing to remind her even once. She was calm & focused always, irrespective of what surprises my ex husband brought to the trial. She remembers every detail and uses it appropriately. I expected history to repeat itself where my ex husband would manipulate his way and distract everyone with lies and nonsense but Gillian kept the whole process straightforward and didn't let my ex-husband drag it out as he very much wanted to. Any legal process is painful but if you have to go through that, then its best to go through it with an attorney like Gillian. I would highly recommend Gillian without any reservations!

"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."
