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!

Highly Highly Recommend

I had an exceptional experience with this law firm. Leslie O’Neal demonstrated unparalleled expertise, professionalism, and dedication. She navigated my divorce with precision, keeping me informed at every step. I highly recommend them for anyone seeking top-notch legal representation. I truly felt l...ike I was in amazing hands through a scary time.

Difficult Circumstances, Best Legal Representative

I interviewed four Attorneys who were all highly recommended by good friends, to represent me in a Divorce complaint. I'm so glad I settled on Leslie O'Neal and her team. She dug right in with setting proper expectations, discussed strategy and the law, and she recommended a course of action based on... my unique circumstance. The end result was far better than anything I could have expected!

Professional, Responsive, & Experienced

Leslie has represented our family in two different co-parenting conflicts. The first was a contested parenting plan modification and the second time she defended me against a contempt charge. In the first proceeding, she got me more time with my daughter and many other small parenting plan changes... that have made a huge positive impact in our family. This was no easy feat as this happened during COVID and everything took longer and was more difficult than it should have been. Leslie also represented me during the day and a half mediation that this deal required and we avoided having to go to court. She fought so hard for us and was responsive and encouraging to us the whole way. The second time she represented me, I was defending myself against a contempt charge. We won that case and I could not have been more impressed with the case she made for me. She was calm and collected, professional, and prepared. In the months leading up, she went over every option and possible path forward, always mindful of how best to keep our costs low. Unfortunately, we will likely find ourselves in need of her service in the future and there is no question that she would be our first choice. Leslie is the best!

Best decision I have ever made

I was recommended Leslie from a friend and this was by far the best recommendation I could have ever received. Something I will be forever thankful for; Leslie coached me through a very stressful time in my life and is the reason I have gotten to spend significant time raising my children. Leslie ...is very professional and knowledgeable and is definitely the attorney you want standing by your side.
