10 Stars for Olivia St. Clair Long

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 O...livia 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. Again, 10 stars for Olivia!!

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.
