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.

Gillian...perfect mixture of fire, logic and calm

I first met Gillian as an associate attorney in my original custody case in 2011 where I was the respondent. Sparing the details, Gillian felt, with me, the crushing blow of my daughter and I being separated by the conniving and malicious tactics of the opposing side. Gillian stayed in contact with b...oth of us as we navigated the waters of keeping our relationship solid through the most trying four and a half years I can recall or ever will I am sure. Gillian is now representing me as the petitioner to regain primary custody of my precious daughter. I am grateful beyond words for her level-headedness, fire when necessary and most of all for having the foresight to be respectful of the sensitivities of all parties involved. I liken her to a military strategist. She stores up her ammunition, saves her energy and intelligence until just the right amount of aggression is needed then applies it only where it will make the most impact. All the while, keeping her client calm and giving them the attention and specific information they need to make lasting choices that are fair and just. I will always consider her my dear friend as will my daughter.

Gillian is simply an amazing lawyer!

My case was very personal and required dealing with aggressive and unreasonable people. Gillian was in my corner from the first meeting and was professional and compassionate throughout the entire process. She fought 100% for me and my family and I'm completely grateful for her efforts. The case w...as eventually dismissed - The main reason for that being Gillian's involvement in the case. I cannot recommend her enough!

Divorce

Gillian was the best choice when it came to my divorce. She kept me informed of my parental writes and helped me get everything I needed and wanted custody wise when it came to my daughter. I will would highly recommend her to anyone in need of a family divorce lawyer.I have recommended her to 2 peop...le So far and will continue to do so.

So grateful I made the decision to hire Gillian.

What should have been a simple, uncomplicated divorce became very complicated and litigious thanks to the opposing counsel, who seemed positively giddy at the prospect of taking the case to court; at which point I was so very glad that I made the decision to hire Gillian. I had absolute faith in her... ability to handle a case that seemed like it might suddenly be headed for court. Thankfully, after nearly 6 months and the OC having filed almost every document that was possible to be filed, we reached a settlement agreement and avoided court. Gillian was familiar with the mediators in Dekalb county, having worked with them many times before, and I believe that was to our advantage. And, being a notary public, I was able to sign all the final documents and have them filed that very day, so that we were completely done. Not how it usually happens, I understand. I must admit that in the beginning she came off as rather short and blasé about things that caused high emotion in me, but I realized soon enough the value of that level-headed calmness and focus in the midst of what to me felt like chaos. There were many times that I called her with the latest unbelievable actions of my wife and Gillian helped calm me down and put it in perspective, for which I am eternally grateful. And what came off as brusque turned out to be more about efficiency and keeping my costs (i.e. her billable time) down, which was truly impressive in comparison to other lawyers. Gillian is not the cheapest lawyer you can find, but I really felt she was worth every penny, and every bill she sent was absolutely reasonable in that I never once felt like her hours were padded. If anything, I was surprised at how little time she billed for some activities, like a huge array of interrogatories and responses to discovery. And Gillian’s knowledge of family law and her ability to anticipate the reaction of the judge to certain motions was invaluable in helping me to make decisions about what course to take during the case and how much to push or not to push on certain topics. Obviously, I cannot say enough good things about Gillian and her skill. She can be trusted to give it to you straight and to be there when you need her.
