Grade A Lawyer

I didn’t know where to look for a lawyer that would have my best interest due to the situation I was in and was referred to Sean. I couldn’t have been happier with the candor, honesty, understanding and communication Sean and his team had with me. He is unbelievably knowledgeable and detailed. Highly... recommend!!

To all in need of qualified representation in a legal battle as I was. I would recommend Mr Sean Sullivan as one of the most qualified and knowledgeable attorneys that I have ever dealt with. We were in a battle for several years and Sean knew how to defend all allegations that were thrown out there.... He is a true warrior for his clients and I would tell anyone who would ask if I was satisfied with his representation I would say without a doubt. He is the man. Paul A Paul Jr. Satisfied client 100%

Very kind, efficient

Not the best time in my life, surely, but Sean made the process much more gentle than I feared it might be. He was very kind, friendly to talk with, efficient in all he did for my case, and I even learned a bit about legal writing through him. Nice and smooth on this end thanks to all of Sean and his... colleagues' work. Many thanks.

Dr. Chris Johnson

I hired Sean to help with a complicated divorce situation. Actually Sean navigated an array of stumbling blocks that were put in front of us. To me he came through both professionally with an understanding personal touch. Sean is easy going with his clients, but tough on opposing counsels. I can ...attest to that. He is very knowledgeable on the law and guided a novice such as me through the divorce court system and process. In short I am grateful for his counsel and the result of my case.

Sean Sullivan - Attorney Review

While Sean specializes in family law, he was recommended to us when our daughter, a very newly licensed driver, had to make a court appearance after a traffic altercation. When we received the attorney of the other party involved in this incident, we chose to seek legal assistance. Sean accompanied... us to court and walk us through what to expect. Sean reminded our daughter of how to conduct herself in court and how to proceed during the process. We are very grateful to Sean Sullivan for his expertise and support. Our daughter's case was dismissed! Thank you, Sean, for helping this new driver (and her parents) through a very tense time.

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.
