Highly recommended law firm for going through a divorce.

Olivia's firm was recommended to me as I was going through a divorce and I am very glad I went with them. Olivia was very kind and helpful explaining the various steps of the process and my actual lawyer Jessica was super knowledgeable, helpful, and patient especially when the process ended up not be...ing as smooth as I thought it would be. Lizbeth, who took my initial call, and Maddie who assisted Jessica throughout the process were also very kind, helpful and efficient. I would definitely recommend O. Long Law to anyone who is going through a divorce.

Olivia is quick, responsive and gets results

Our family needed some emergency counsel on a pending matter and Olivia jumped right in to help. She was kind, responsive, thorough and helped us navigate a particularly messy situtation.

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.

Avvo Rating

Our Rating is calculated using information the lawyer has included on their profile in addition to the information we collect from state bar associations and other organizations that license legal professionals. Attorneys who claim their profiles and provide Avvo with more information tend to have a higher rating than those who do not.

What determines Avvo Rating?
  • Experience & background Years licensed, work experience, education
  • 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.
