Very Professional

My lawyer took my case right away without hesitation. She utilized all resources available to her to create documentation well over 100 pages in a case involving theft by deception against my ex-wife. Taking into effect the winter break and Christmas vacation, my case could not have been resolved an...y faster without even having to meet in front of a judge to resolve it. Knowing future problems might arise, I am keeping Mrs. O'nan on retainer.

International Divorce/Custody

Gillian did a great job communicating with me on what was going on and finding solutions for the difficult problems in dealing with a international case. She is easy to talk to and answered all my questions in a timely manner.

Professional and Courteous

Gillian provided excellent legal services and answered all my questions in a timely manner. She kept me in the loop on all court proceedings and actions from the defendant's attorney. As divorce is a difficult process, Gillian made me feel comfortable and gave me sound advice and was supportive thr...oughout the process. In mediation, she was able to make everything work out to my favor. I appreciate all she has done for me and would definitely recommend her.

Gillian Fierer O'Nan - Excellent Divorce Representation!!!

My original attorney that moved out of the state highly recommended Gillian Fierer O’Nan. I feel very fortunate that Gillian took my case on such short notice. She was so efficient and on the ball from day one. Always returned my calls quickly. She was very persistent in working with my extremel...y difficult, mean unreasonable spouse. Gillian got my divorce over with promptly. I am so thankful to have been fortunate enough to have had her represent me. I would certainly recommend Gillian to anyone requiring legal help.

"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."

Avvo Rating

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
