I Have Been Fortunate to Have Joe O'Brien Represent Me and You Would Be Fortunate to Have him as Your Attorney

Joe has been my divorce attorney for almost 10 years (not a typo) for the actual divorce and lawfare from my ex since then. Recently, Joe won at trial for me where it was ruled that my ex was cohabitating and my maintenance therefore terminated. Cohabitation is considered difficult to prove and win. ...It has to be presented using a very specific legal framework and Joe did a great job. Working with and observing Joe over a long time, I can tell you that he is the most professional and polished attorney in the courthouse. Joe is very practical and he tries to resolve issues economically. He has advised me not to waste money on unrealistic legal action when other attorneys may be glad to charge you billable hours regardless of the odds of winning or the vale of winning. And when the other side will not be reasonable, Joe is all-in on going for the win. Joe knows the law cold and he is strong technically regarding court procedures and rules which is very important at trial, and I have seen him run circles around other lawyers. Joe appears to have a good rapport with the judges which makes sense because he is smart, honest, prepared, and does not waste their time. You want an attorney who has credibility with the court. On top of all that, Joe is a nice person. He is very respectful of others, and maintains his composure even when others have not been respectful to him. That is a strong flex and is a sign of power and control, not weakness. I have been fortunate to have Joe represent me and you would be fortunate to have him as your attorney.

Exceptional Advocacy & Compassion - Highly recommended!

Joe is an outstanding attorney who exceptional leadership with a keen legal mind. From day one, Opal O’Brien provided clear strategic guidance, ensuring I felt confident and informed throughout the process. Joe’s responsiveness is a key strength, always available to address concerns and provide tim...ely updates. Beyond just legal expert, Joe demonstrated true leadership, advocating fiercely while maintaining a thoughtful, intelligent approach. I couldn’t have asked for better representation. I highly recommend Joe!

I'll refer Joe to anyone I know needing a family lawyer!

I was referred to Joe from a friend that used him, and I am so glad we hired Joe. He helped us navigate a year long battle with my narcissistic ex and the trying opposing counsel my ex hired. Joe is NOT a lawyer that is a money grabber and tries to extend the case as long as possible. He did ever...ything he could to try to move our case along in the system, because he actually cares about his clients (I know, a shocker in the lawyer world!) He was honest and patient with us, and responded in a timely matter for calls and emails. I felt that he billed us very fairly as well (I went through 3 lawyers in my first court case, and some of them billed for the most ridiculous things). Near the last 3/4 of our case, it was financially rough to pay in full for a few of the bigger court date months. Joe was extremely understanding and let us do a payment plan which helped a lot and we were very grateful for. Not everyone is willing to do this, so it truly shows Joe is compassionate and sympathetic to what his clients are dealing with financially and emotionally during an already stressful time. Mornings before court status, Joe would call me to make sure he had all the facts correct and we would go over a quick synopsis of what he was going to bring up to the judge. He argued well for my case, and stood up for the best interest of my child. There were a few things I was stubborn on when I shouldn't have been, and Joe would calmly explain to me what he thought was the best route to take and why. He never spoke down to me in these instances and treated me as an equal. I did listen to his advice and I am really glad I did. I started out with what he said was, "one of the worst agreements I've ever seen" and we got it to a much, much better place. Some of this was due to my ex making extremely poor decisions and the GAL realizing my ex was not going to change, but Joe helped in crafting a well written agreement. When the GAL gave us her recommendation synopsis, it was a hastily written, poorly worded document. She left out so much of what we had talked about and what she said she recommended in front of the judge. I basically crafted the entire final agreement, and put in almost everything Joe had written in his original draft. In the end, we did not have to go to trial and my ex lost a lot of his decision making abilities and visitation. Lastly, I appreciated Joe's legal assistants. They were always very kind and helpful. Whenever I needed something, they usually responded very quickly which I really appreciated. TLDR: -Joe will argue well for you and not waste your money -Joe will try to move your case along as best he can in the very slow court system -Joe actually cares for his clients

The Best Attorney for Family Law - Cannot Recommend Enough

Joe is an outstanding attorney and was successful in securing my first win in my challenging family law case. Before working with Joe, I had three previous attorneys who were unable to overcome the litigious nature of the other party that would throw everything at the wall to see what would stick.... Joe is incredibly knowledgeable, understands the statute and case law inside and out, and can properly assess the situation. His billing is always fair and transparent, which has been a change of pace from a prior attorney that would overcharge. Most importantly, Joe genuinely cares about you as a person, not just as another case file. If you're in the unfortunate situation of dealing with a family law matter and need an attorney who will truly advocate for you, I highly recommend choosing Joe as your first attorney. He’s the attorney you want representing you.

Excellent attorney!

Joe was vested in my case from the start. He put in the time to research case law that led to the dismissal of my ex husband’s motion to terminate maintenance. He is dedicated, well versed in the law, professional and the communication from his office staff is excellent. Highly recommend!
