Exceptional Attorney with an Incredible Team

Many people who knew I was going through a divorce are still amazed that I was able to finalize it in less than a year. Leslie and her team made that possible with their impeccable work, professionalism, and dedication. She treated me like family, kept me informed, and was always one step ahead—no ma...tter what my ex threw our way. Leslie secured a settlement beyond what I expected and helped me realize I truly deserved it. Her associate, Ms. Heikkila, and the entire staff—including the receptionist, Madison—were always kind, knowledgeable, and ready to assist. No matter when or how many times I call, someone was available to answer my questions or provide the help I needed to ease my concerns, showing the team's outstanding commitment. If you need a sharp, compassionate, and results-driven attorney, I highly recommend Leslie. She goes above and beyond, and I’ll always be grateful for her exceptional service!

Reunited my Family

Mrs. O’Neal has changed my life forever. I went into her office hopeless, lost, and depressed. In my case, I hadn't seen my son in person for over 2 years. Leslie took her time to understand every detail on what was happening in my life. She went to bat for me, advised me, and was always there for me... when I had questions. She is sincere, strong, and fights for what is right. I went into her office not having seen my son, when in the end, Mrs. O’Neal helped me gain full custody back. My son now lives with me and I owe it all to her hard work and dedication. Everyone in her office was so accommodating and caring. She even went as far as advising me/ answering questions after our case was settled. I am beyond blessed to have called Leslie my attorney. I will forever be great full!

Leslie was a LIFESAVER

I was referred to Leslie a few years ago by a former client, and we spoke a few times while I was trying to decide the fate of my marriage. She was always patient, kind and matter of fact with both good news and bad. When I finally decided to file (2 years after we met) she had maintained notes from ...our previous meetings and knew right where to jump in. Divorce is an emotional process and she was certainly the 'steady hand' I needed to make it through the process. She is extremely thorough and a great communicator to let you know what is going on each step in the process. I can't say enough great things about her and her staff, and have recommended her highly to any of my close friends contemplating divorce.

High Quality Professional

Leslie and her team were absolutely fantastic to work with. They were organized, efficient, competent, knowledgeable, patient, and sensitive to the nature of my situation. They were clear about all expectations and there were no surprises. I had an uncontested divorce and it was filed and finalized a...ll in one month. My process was smooth and Leslie even orchestrated a creative way to set up child support so that my son would be protected long term. Overall my experience was beyond satisfactory. I feel very fortunate to have been represented by Leslie.

Best Lawyer Around

I met Leslie at a networking seminar in Atlanta. We met up a few weeks later to discuss business, and we started talking about my divorce. After an hour and a half, I was ready to fire my current lawyer and retain Leslie. She is well versed in the law, and brought to my attention things that could ch...ange. Additionally, she gave me something my previous attorney did not... and that was Hope. During the whole process, Leslie was optimistic in my case, and never wavered in expressing we had a strong case. Her and her staff went above and beyond in preparing and filing everything in a timely manner. Her courtroom behavior is something to revel. She is professional. and at the same time, a lawyer you never want going against you. I have recommended her to several people, and will continue to recommend her in years to come. Thank you Leslie for everything!!
