Gregg Went Above and Beyond When It Mattered the Most!

I highly recommend Gregg Greenstein and am very grateful for his help and guidance. He took on my case when others were not willing to, which meant a great deal to me from the start. Gregg was supportive, knowledgeable and went above and beyond even after my initial case to see everything through an...d get it resolved. I also appreciated knowing his team, including Christine and Brittaney were supporting things behind the scenes. Having that level of support was reassuring to me. I’m very thankful for his professionalism and dedication, and I would highly recommend him. I am so grateful for Gregg and his team.

Focused, Experienced, and Strategic

Divorce can be an uncertain and difficult process to walk through. When looking for a divorce attorney, a trusted friend recommended Gregg and mentioned how grounding it was to work with him — and how important that quality is when everything else feels unstable. I have to agree that Gregg brings ...a focused, steady presence to the process. Even though my ex-spouse was the one to file, Gregg took the lead and drove things toward resolution while advocating for my interests. His experience showed in his strategic approach to filing motions, and his ability to quickly draft agreements — drawing on his deep body of past work — saved significant time. He got me through the process with equal parenting rights and other meaningful outcomes. Gregg's assistant Christine was the first person I spoke with, and she set the tone immediately — offering tremendous empathy, genuine understanding, and practical financial guidance at a moment when I needed it most. If you're navigating divorce and need someone who is calm, experienced, and strategic, I'd recommend Gregg without hesitation.

knowledgeable and caring

Gregg was a very attentive lawyer who is very knowledgeable and cared for the outcome of my case. His calm demeanor was very beneficial going up against the other party.

B ST Divorce Lawyer

Gregg was my guiding light through a very difficult, tenuous and scary time, my divorce. He helped navigate all the sink holes and was my rock in maintenance negotiations. Then, three years later, my ex threatened to enact a massive reduction in my alimony. Gregg presented case law and built my ...case for the best outcome, financially. Not only is my my lawyer -whom I recommend, always but he is my friend.

Beyond an Amazing Attorney

Gregg is beyond amazing, intelligent, and one of the hardest working individuals I have ever known. I never expected an attorney would work the hours Gregg did to ensure my divorce went the best it could. My situation seemed easy at the beginning, but my spouse made everything extremely difficult and... Gregg made sure to walk me through everything. The times we had hearings Gregg always was prepared, and made sure I was prepared with multiple Zoom meetings. He then astounded me during the hearings by being able to cite court cases off the top of his head to object to the other side, or prove a point. The immense knowledge he has at the drop of a hat is truly awe-inspiring! He made me feel confident during hearings as well and made me so proud to have chosen such an amazing attorney who would shock anyone with his intelligence. As I stated above Gregg worked beyond the normal business hours at times to ensure any questions or concerns were taken care of and to make sure court orders, preparation for court etc was done correctly. I don't believe many people would do that, and the fact that he made sure that we were prepared for court with multiple Zoom meetings that took up even more of his time was a blessing. I deferred to Gregg's judgment on many things as I didn't have the ability to make decisions on my own very well, and what made a huge difference for me is how he treated me. I spent 20 years being silenced and Gregg never did that; he actually made sure to listen to what I said and made a point to make sure my voice was heard. This was something that left me in tears because I hadn't experienced that in so long and I appreciated that more than I could ever express in words. Gregg was so competent about divorce case law that he almost predicted the outcome of every court order, hearing and court ruling before it ever happened. That left me amazed and further instilled in me that I made the correct decision on choosing Gregg. Gregg was so meticulous about every single letter, court order etc that he made sure to do almost everything on his own, which was shocking to me. Most attorney's defer to their legal assistant with that type of work but Gregg's meticulous nature overruled that. When I did work with his legal assistant (Christine) she was just as compassionate and effective as Gregg was. While the divorce process was beyond stressful and scary Gregg made sure to be incredible at every juncture to inform me of the possible outcomes and options. There aren't many people in life these days that make a difference and major impact on others, yet Gregg did. I truly think Gregg is one of a kind and the world is a better place because of him and his amazing help. Any person who has to go through a divorce case would be in the best hands with Gregg, and I will never say otherwise. At the end of my case I considered Gregg as family since he treated me more kindly than any other professional I have ever come to known. He made me believe there is good in this world, and that he is rare gem of an attorney that will leave anyone in the best hands. Thank you Gregg for everything; I will never forget you, and never forget how amazing you are!

Relationship: Opposing Counsel on matter

"Attorney Greenstein is a "Lawyers Lawyer'. That is to say he takes his Oath of Admission to the practice very seriously. He treats everyone with civility and respect. Gregg has appeared on Dr. Phil's Television show as an expert Family Law practioneer. his knowledge of the law and it's technical underpinnings is second to none. However, he is always anxious to utilize common sense, bypass expensive legal proceedures and craft an agreement that is fair to each side. Speaking as opposing counsel, we had several disagreements concerning both the Law as it applied to our case, and the underlying facts. Gregg was quick to utilize problem solving techniques and get past our points of contention. In my cases opposing Lawyer Greenstein, my clients were happy with the results of my representation and I bellieve that his client's were also pleased with the final result of our efforts. In the Family Law Practice Arena, this is the ultimate test of both attorney's skill and dilligence."

Relationship: Worked together on matter

"During the last 10 years, I have worked with Gregg on many cases in which we had clients in common who were facing both criminal case issues and divorce/custody issues. I have found Gregg to be a top shelf attorney. He is very conscientous, extremely detail oriented and always thoroughly prepared on his cases. He is very well versed in the case law and great in the courtroom as well. With his divorce talk show career and singing career background as evidence, Gregg is really a well rounded, and well regarded, attorney. Would definitely recommend Gregg to anyone dealing with divorce or child custody related issues."

Relationship: Opposing Counsel on matter

"I endorse this lawyer, Gregg Greestein, because he was not only professional, ethical, and cooperative, but very gentlemanly and in family law that is something I have found rarely in my short time practicing law. While in a contested grandparents visitation matter his lawyering skills, knowledge, and cooperation led both parties to an amicable resolution that will be beneficial for all parties involved. As a young lawyer it has been very helpful to have the opportunity to work and learn from another lawyer like Mr. Greenstein."
