Trustworthy Defense is Key

In times of need and desperation when caught up in serious legal issues, the guidance and expertise of a professional is essential. It's difficult to find trustworthy defense, but not impossible, I feel very fortunate to have found Sean O'brien from O'Brien & Murphy-Aguilu Law Group. With him I found... empathy and most importantly the strive to fight for what was fair for me, he kept me well informed from beginning to end as well as demonstrated his knowledge, by putting it all in practice. It was more than evident that all his effort and expertise were put towards my defense as he gained a successful outcome by obtaining the dismissal of my case. I am infinitely grateful with Sean O'Brien and HIGHLY recommend his services.

Best Defense!

In 2014 I found myself urgently needing a criminal attorney. I was referred to O'Brien & Murphy-Aguilú's Law Group. I left a voicemail and Mr. O'Brien called me back within 30 minutes. After a lengthy conversation, I felt at ease. They are easy to talk to and will thoroughly explain the process and ...keep you informed every step of the way. They answered all my text messages and calls right away. There was never a time where I felt in limbo. Throughout this process I was treated with compassion and respect. They are very knowledgeable and work very quickly to obtain a favorable outcome. I am truly grateful for everything they did for me.

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.
