Excellent service
I hired Diane for a small legal matter while living out of the area. Her timely and professional response to my legal matter was greatly appreciated. I was very satisfied and impressed with the personal care and service I received after hiring her. I would gladly recommend her services in the future to anyone that asks or is in need.

Trustworthy, personable, realistic
I would recommend Diane Grecco to any friends or strangers in need of a lawyer. It quickly became apparent that she had built up a reputation and personal relationship over her career with the different judges, prosecutors, and court clerks that I came into contact with during my case. I had never been required to go to court or stand in front of a judge and she was always professional and handled my affairs in the best of my interest and also explained all possibilities and explained the realistic percentages for different paths to go forward in navigating the legal system. Looking back, I would have been completely lost on my own or just another number had I chosen to be assigned a public defender. In the end, I received a very positive court decision due to Diane's handling of my case, while avoiding more court dates. She had professional relationships with the judge and prosecutor and was able to meet outside court to discuss my case and get it resolved without appearing in court or in front of a jury. In our meetings in her office, I always felt listened to and she took the time to explain how ''these types of things'' usually turn out. I received personal phone calls and emails updating me on my court proceedings and always felt informed as to what her next step would be and what I would need to do.

Very patient and knowledgeable
I had my license suspended awhile back and I turned to Diane to help get it settled. She was patient with me and exceeded my expectations as well as got my case resolved quickly. She knew exactly what she was doing and made me feel confident in the outcome.

Excellent work
Diane is a great lawyer and advocate. She helps her clients navigate the legal system in a way that is very reassuring. She is a very hard worker.

Quality and experienced legal representation.
I have worked with Diane for years. She is truly committed to her clients and obtaining the best results possible. She brings a lot of hard-earned experience and knowledge into her practice. She has acted as a mentor and role model to me and many other of her colleagues. Diane is a stand out in a sea of faces in the legal business. She has genuine compassion and concern for her clients yet she is a tough, focused litigator who is respected by judges, prosecutors, and her peers. I would highly recommend Diane if you're looking for an attorney who will fight hard for you, yet always maintains an attitude of professionalism and respect.

I highly recommend Diane Grecco
Diane is far more than a great lawyer. I worked with Diane to finalize my divorce and was very pleased with the results. She is very good at explaining things to her clients and making sure they are aware of the all the options they have. She never left me wondering about anything and always answered my questions quickly even at nights and weekends. Diane also pays close attention to everything and leaves no room for errors. Her support and experience helped me finalize my divorce sooner than I expected and I actually got everything I asked for. During the period I worked with Diane she was very helpful and extremely friendly. I would definitely recommend Diane and her legal team to anyone. With her you can feel secure in knowing that your best interest is her top priority.

Caring, supportive, genuine legal guidance.
About nine years ago I was falsely accused of a very heinous crime for which I did not commit. Diane was working then with the local public defenders office and took on my case. From the very beginning she treated me like a human being, not like the monster that the police and courts attempted to portray me as. She fought for me tooth and nail and gave me not the slightest doubt that she believed 110% in my innocence and she fought for me just the same. When everybody in my life turned their backs on me she was one of the only people in the world that stuck with me not just as my attorney but as a friend. She is a lawyer that cares for her clients and doesn't simply do her job out of a sense of obligation or a desire for the money that it may bring but rather because she genuinely wants to help people who need help and are not in a position to fight for themselves in the legal arena. Though my case did not turn out the way in which we would have hoped it too, I am confident in saying that there are not goin to be too many lawyers in this world who are going to care as much and fight as hard for their clients as Diane Grecco. If you want a lawyer who is knowledgable, reliable, caring, and refuses to give up on you than she is the person to have on your side. Even nearly ten years later she still communicates with me and shows interest in the direction that my life has taken after representing me. She is definitely a one of a kind person who will help u get your legal problems situated in a desirable way.

Falsely Arrested And Scared
I was falsely arrested and charged with a DUI.I felt hopeless and discouraged. Then I had an appointment with Dianne Grecco. She listened intently to my story and interviewed my witnesses. She went to bat for me and the charges were dropped. Justice is something that can't be taken for granted but I had faith in her integrity and ability to get to the truth and it was well placed. Having a good lawyer is as important as having a good doctor. I highly recommend Dianne Grecco for swift and effective results. She is a cut above the rest.

This review is from a potential client who consulted with this attorney.
| Consulted Attorney
Used for a consultation
Was largely underwhelmed with my consultation. I was given information about a speeding ticket that I already knew or could have easily deduced on my own. She was very unconfident in her answers and had me call her for my consultation having done very minimal review of the facts - she had yet to even look at my ticket. She would not recommend a course direct course of action, just basically listed all of my options-- which I ALREADY knew, they're right there on my ticket.. Did not leave me with confidence that she could perform the task at hand.

Response from Diane Grecco October 11, 2017
I always welcome reviews and feedback. I am concerned that this review may have been submitted because I expressed that I did not want to handle your case. I am sorry that you feel this way but I would like to add to your comments so potential clients have additional information upon which to form an opinion. You emailed our office at 2:45 PM yesterday and wanted to know "the next possible steps" regarding a speeding infraction. I responded immediately, as I often do, but from my vehicle at 2:57 PM. I indicated that you could call me, which you IMMEDIATELY did, and we discussed the pros and cons at some length. I do like for people to be well-informed about what I might be able to do for them, but also what they might be able to do themselves, so they don't have to incur the expense of hiring an attorney. Your inquiry was handled no differently. A phone consultation is customary and appropriate when clients do not live in the same geographical area, like in this situation, and since I was driving in my car at the time I indicated that I had not yet read the report that you had attached to your email approximately 15 minutes earlier. Most importantly, to reiterate, no attorney can guarantee a result and can only zealously try to accomplish the best result for their client. My goal always!
