  • Rickey A Fitzsimmons

    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.

    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.
