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!

Amazing Family Attorney

To say that I am so thankful and so appreciative, would truly be an understatement. Leslie was my legal counsel in a stepparent adoption, and she went above and beyond for my family. Leslie has shown that she isn’t just a lawyer, but she is someone who truly cares, she’s someone you can trust. She li...stens to the details and gives you straight answers. She is a no BS lawyer. She doesn’t sugar coat anything and will tell you the truth either way. She fights hard for her clients and never once did I feel anything but 100% confident in her. I am so truly thankful for Leslie. I am forever in her debt, truly.

No Regrets!

Leslie walked me through the toughest battle of my life. Her expertise in the field was obvious from the beginning as she explained each step in the process and treated me with respect. Her courtroom acuity impressed me and proved I was in good hands. During the entire process, Leslie never failed to... bring me through on top with smart advice, knowledge, and fairness. One of my wisest decisions was to hire Leslie when I needed the best.

Forever Thankful

Leslie O’Neal is an extraordinary attorney. She approached my custody case with determination and dedication that are unparalleled. Whether by email or phone, my questions and concerns were promptly addressed with clear and thorough answers throughout the entire process. She helped to guide and in...form me through the hardest season of my life. Mrs. O’Neal took the time to gather all the information regarding my case and then put so much consideration into the best way to approach it. The attention to detail and preparation that she devoted into the custody hearing combined with her effectiveness in the courtroom led to a successful result. Her representation for me in the courtroom was outstanding as she advocated for me with strength and resoluteness. I am genuinely overwhelmed with gratitude to Mrs. O’Neal for the role she played in allowing me to retain primary custody of my daughter. I cannot recommend her enough!

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.
