A true blessing!

Gillian handled my divorce case with perfection. She applied just enough pressure to push for resolution without creating unneeded animosity, but I also took comfort knowing she had a more aggressive gear should it be needed. Because of her measured and reasonable approach she secured for me the te...rms I wanted, in an expeditious manner, and without a huge bill. I would recommend her a thousand times over and am so glad that I chose her to represent me.

HIGHLY recommend!

I (unfortunately) have had two previous lawyers on 2 previous occasions due to divorce/child custody issues with my ex husband (both of whom did an absolute sub standard job). I was so pleasantly surprised upon meeting with Ms O'nan and quickly came to be extremely impressed with her obvious intellig...ence, legal knowledge, approachability, and absolute effectiveness as my lawyer. She was always available, responded quickly and efficiently. She commanded respect in any legal setting and is obviously held in the highest regard by her peers. Her support staff is also excellent, as I also had the pleasure of working with a junior attorney Stacey from her practice on 2 occasions. I always felt mine and my son's fate was in the best hands possible with Ms O'Nan and her team. I couldn't have asked for a better outcome (all things considered) and know (thanks to her absolute attention to every detail, and thoroughness) that there are no potential gaps/unaddressed issues in the legal agreement/documents that resulted from my most recent child custody revision process. Bottom line, I would highly recommend Ms O'Nan without absolutely any reservations. I'm so fortunate to have had her as my legal counsel this time around!

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!

Gillian was kind and professional through the months leading up to my divorce. I felt that I got the best settlement possible with her guidance and knowledge. I have already recommended her to my friends who have found themselves in this kind of situation.

"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."
