Incomparable Legal Expertise With Exceptional Results
I'm very thorough when it comes to researching and finding the best of the best legal representation. I was charged with assault and domestic violence by my spouse and sadly both charges were bogus from the start. After my initial consultation with Attorney O'Connor he went right to work on my case. I hired Attorney Edward J. O'Connor, Jr and he provided thorough and comprehensive legal wisdom, expertise and execution of not one, but two cases and brought them to resolution. Both charges were dropped and were it not for Attorney O'Connor's excellent legal mind and tenacity, I would have been put in prison. I highly recommend Attorney O'Connor because he is a well respected and a second to none lawyer, he's simply the best. Were it not for Attorney O'Connor I would have lost my two young children and for this I'm thankful to God for directing me to this exceptional lawyer. If you need a lawyer that happens to be the best in the legal arena, Attorney Edward J. O'Connor and his staff should be your first and only choice for legal representation. Thank you Attorney O'Connor.

Protective Order
I am very thankful that I hired Attorney O’Connor. I was devastated about getting a false Protective Order charge against me and I thought for sure that because I was a male, I would not get treated fairly in court. I was represented great and the Protective Order was denied. Attorney O’Connor and his Staff are the best. From my first call to the end of my hearing, Attorney O’Connor and his Staff was available and when Attorney O’Connor wasn’t available, he responded to my calls and emails in a timely manner to advise me on all of my issues. Attorney O’Connor is very professional and I would recommend him for anyone. Thanks for your professionalism and help.

Defense Attorney Recommendation
On the first day that we hired Mr. O'Connor he entered his appearance and filed motions on behalf of our son. He sat down with us on the first day of our meeting and began to outline what his approach would be to the case. He worked hard in retrieving evidence from the Prosecutor to ensure that he received the evidence in a timely fashion. He kept us abreast of all incoming motions and oppositions. Mr. O'Connor was timely in responding to all of our concerns and questions. We highly recommend Mr. O'Connor as a qualified attorney who has a lot of experience. He made us feel as if we were his only clients. We would recommend Mr. O'Connor to anyone seeking a attorney.

Great service
Mr. O'Connor was wonderful to work with. He served as a great source of knowledge and provided options for my case. Mr. O'Connor even provided advice for my husband, who was not his client. From our initial consultation, I felt safe with Mr. O'Connor and that he would provide the best legal expertise possible. I would definitely recommend Mr. O'Connor.

The best I've ever had!
Ed has always been there to answer any questions and get right on the case when I need him. I like the fact that he will just help me over the phone with my problem(s). He seems to be in this line of work to actually help people and not himself. He is honest,sincere and a genuine" good guy". He is extremely competent and thorough.

Comfortable and Confident
Mr. O'Connor made me feel comfortable and confident that my case was being handled efficiently and professionally. He was careful to explain which direction we took would be in my best interest and most cost effective. He handled the case seamlessly and I felt that I was in good hands. His demeanor was professional, yet firm when necessary. I would definitely refer Mr. O'Connor to my friends and family! Thank you for taking such good care of my case and my family.

Another Chance
I would definitely recommend Mr. O’Connor to any and everyone in need of a dedicated, loyal and trustworthy attorney. Mr. O’Connor is very very knowledgeable of the laws and always presents himself in a very professional manner. Mr. O’Connor is very easy to talk to and this is not always an easy thing to achieve considering certain circumstances. Mr. O’Connor’s office is very comfortable and laid back atmosphere, and I found my visit there very comforting, even considering the stressful circumstances. Mr. O’Connor went above and beyond what was necessary, and took care to work every aspect and angle of my case. Had it not been for Mr. O’Connor I could and probably would have been penalized very badly for my mistakes. Thanks to him and his hard work and diligence. I’ve been given another chance to grow and learn from my mistakes and I thank him dearly. Thank you so much Mr. O’Connor.

Maybe he forgot?
I hired Ed O'conner for 2 different protection order cases (at $1500 a pop). The first one was dismissed by the judge as it was clearly ridiculous and the judge had some common sense. The second one, however, became one of the worst things that happened to me party due to the incompetence of this lawyer. Less than 3 weeks after the first, the second was filed for unrelated accusations. CPS unsubstantiated the claim. In our discussions leading up to court it was very clear that we would take it to trial. I provided Mr. O'conner with any information he requested. At the hearing, he decided that we needed to make a 'deal' and not go to trial. I argued with him and he shamed me, saying I was a pain to deal with. How could I be confident to go to trial with a lawyer that clearly did not want to? I was between a rock and a hard place. I ended up with supervised visitation of my child, when before I had half custody. I was defeated by my own lawyer. Later, when problems arose due to the agreement not being written specific enough, he argued that I was wrong about what the deal was. I asked if he checked his notes and he answered 'no'. I reminded him that last time I spoke to him he didn't even remember who I was so how can he be so sure of his memory of such a specific detail? He responded that I wasn't making any friends like this. I told him how unprofessional and unreliable that I felt he was and am now conveying this information to save anyone else from this type of situation. Luckily, I later found a great lawyer who was able to undo all of the foolishness of this situation and restore half custody and my relationship with my child. My current lawyer and the judge both stated how it was a terrible decision to make that deal when CPS unsubstantiated the charges and I was given bad legal advice. Be warned.
