Trusted During Difficult Times

Real clients on what it's like to have us in their corner.

"I have had the pleasure of knowing and working with Attorney Olivia St. Clair Long for almost a decade. I cannot say enough positive things about her as a person, how she practices law, and her character. I team up with her so I do not have to go against her, and her work is second to none! While Olivia will fight hard for her clients, she is also able to switch over to settlement mode with the same tenacity and in the interests of gaining the legal relief her clients request. Being in her field of law is quite emotional. I am impressed at how compassionate Olivia is with her clients, especially given the high stress matters she is retained therein"
"I had an excellent experience working with the team at O. Long Law, during a very challenging time in my life. The attorneys and paralegals were knowledgeable, compassionate, and always took the time to explain every step of the divorce process clearly. They handled my case with professionalism and made me feel confident that my best interests were being protected. Communication was consistent and timely, which helped reduce a lot of my stress. I would highly recommend this firm to anyone in need of reliable and supportive legal representation."
"Jessica was my representing attorney for my prenup. After being initially intimidated by the idea of a prenup, I felt comfortable talking with her. She is amazingly intelligent and personable. She went line-by-line through the draft prenup, explained everything to me, and made edits based on my feedback. She even thought ahead on things that I wouldn’t have even considered. I would recommend her to any of my friends needing representation."
"Olivia gave me advice in a high-conflict divorce situation - pro bono publico- and offered sound, clear and loving guidance. It was so clear to me that she is infinitely knowledgable and clear-headed. Strongly recommend. If you are part of a queer family, recommendation is even stronger, though I'm certain she'd represent everyone with care and honor."
