Olivia is a great head attorney and stepped in toward the end to resolve the issues quickly

I chose this firm after meeting with the head attorney, and I felt very confident after speaking with her. My case was later handled by another attorney, who may have been newer, and I noticed several drafting errors in my MSA that I needed to point out. This made parts of the process feel slower tha...n expected.I do want to acknowledge and appreciate Olivia’s involvement toward the end of my case. She is very knowledgeable, and her quick attention helped resolve the remaining issues smoothly.

Outstanding Family Law Attorney!

Olivia, who is incredibly intelligent in her field, with impeccable credentials, was referred to me while I was going through a very complicated divorce. She was immediately accessible, listened, which you don't find often in this field of law and gave me advice that, to this day, I pass on to other...s that are going through the awful process of a divorce. Her insight to the core issues was spot on and gave extremely constructive advice. Talk about a fighter for your side, you won't find a better one. She's cognizant of the psychological pain that is inherent in this life altering event and provides outstanding guidance. I refer her and her firm to anyone that I run across that is unfortunate to have to go through this. Not hiring her will be a mistake if you are in this situation where you need outstanding representation.

Outstanding!

I am an experienced business attorney who has referred several clients to Olivia. Everyone has thanked me profusely. Her combination of professionalism, knowledge and practical tenacity is very impressive. Giving her 5 stars is the easiest decision I made today.

Exceptional Family Law Team

I can’t say enough good things about Olivia and Alex. Going through a divorce and post decree litigation has been one of the most stressful experiences of my life, and having them in my corner has made all the difference. Olivia is incredibly knowledgeable, thoughtful, and strategic. She takes the... time to explain things in a way that’s easy to understand and always makes me feel heard. Alex has also been wonderful to work with. She’s responsive, detail oriented, and always willing to help whenever I have questions or need something addressed. Throughout my case, they’ve both been professional, compassionate, and genuinely invested in helping me navigate a very difficult situation. I’ve always felt that they were advocating for my best interests while also being honest about what to expect. If you’re looking for a family law team that truly cares about their clients and works hard on their behalf, I would absolutely recommend Olivia and Alex. I’m very grateful for everything they’ve done for me.

Business Divorce/Asset Split - Great for Attorney Referrals

I referred a client to Olivia during negotiations in a business divorce matter when I had to go on leave. Olivia and team picked up right where I left off and finished the deal. Six months after closing, the client still tells me how well the case finished for them and how Olivia was kind, smart and ...attentive to the business's needs. I echo my client's assessment and note that Olivia also is a pleasure to co-counsel with. If your matter involves a business or asset split, hire Olivia.

  • 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.
