KGG Law, and Barry Kantrowitz in particular, set the bar high for what a thorough, practical, strategic, compassionate and smart lawyer can be. Everything about Barry's advice and representation was exemplary and the stress mitigation that resulted was invaluable. On top of that, the ultimate result Barry achieved was beyond what was reasonable to expect and we are forever grateful. Often, people say that you hire a lawyer to prevent a problem. Sometimes, unfortunately, you need an attorney to solve a problem and I could not recommend Barry and his firm any more highly in that regard.Posted on Google

My dad had a great experience with this law firm. From the very beginning, the team was professional, knowledgeable, and always willing to answer our questions. They kept us informed throughout the entire process and made what could have been a very stressful situation much easier to handle. We truly appreciated their dedication, honesty, and hard work. Thanks to their support, my dad felt confident every step of the way. We are very grateful for everything they did and would highly recommend this firm to anyone looking for reliable legal representation.Posted on Google

I had a wonderful experience working with Sam Smith. He was very responsive, thorough, and easy to work with from start to finish. He walked me through everything clearly and made what started as a very stressful situation for me into something completely manageable. I would not hesitate to recommend him and the firm!Posted on Google

Kate Carballo is a dedicated, passionate, and creative attorney whom I had the pleasure to lecture with at a state trial lawyer's conference. Kate's lecture demonstrated how she uses her innovative and "out-of-the-box thinking" to achieve outstanding results for her injured clients. That Kate is certified by the Supreme Court of New Jersey as a civil trial attorney is a testament to her skills, experience and commitment to excellence.Posted on Google

Was referred to KGG law by a friend and could not have asked for better legal representation. They walked me through every step of the process after my accident and began every call with “ how are you feeling” which was just one example of how much they care about their clients. They handled my case very efficiently, professionally and courteously. My attorney Kate Carballo was a rock star! So clearly experienced, she consistently made me feel at ease with the process. Highly recommendPosted on Google

We had a great experience with the team at KGG Law. While it was a traumatic time for our family, they made it very easy for us and explained all of our options. They even performed due diligence to make sure that after our settlement, there would be no further issues which I think is even more important than the settlement itself. Thank you!
