  • “Jason Fellner and his team represented me as the defendant in a tenant vs landlord case. I was referred to Jason from my insurance company and could not have been happier. Jason was very professional and efficient as well as patient and understanding. Jason educated me and prepared me for the time it would take to get the case settled in mediation. Jason kept me informed throughout the process. In mediation Jason worked out an arrangement that satisfied my unique needs. I would recommend Jason highly and give 5 stars for his performance. Thank you Jason.”

They were methodical and persistent, avoiding unnecessary theatrics or posturing, and kept me informed at key points. Ultimately, their determined efforts secured a settlement that resolved the matter, highlighting their dedication to achieving a favorable resolution. Throughout it all, it was clear they had my best interests at heart and genuinely sought to make things right.

    Jack O. and Anneke S.

  • “Jason and Lindsey acted for me in a malpractice matter resolved in mediation after two years. Their advice throughout that time was balanced and well-informed. They clearly articulated the strengths and weaknesses of the case, yet I knew if the matter had gone on to arbitration Jason would have been a formidable force in court. It was, however, their nuanced understanding of behavior and motivation that impressed me most and that skillset eventually led to an excellent negotiated settlement. They’re smart, they listen well, and importantly, they have a sense of humor. Dare I say they made a very unpleasant experience enjoyable? I couldn’t recommend them more!”

    Gabrielle L.

  • “From our first meeting, it was clear that Jason and the team understood not just the legal complexities of my case, but also genuinely cared about my concerns. They had a remarkable knack for explaining complicated legal terms in a way that made sense, which eased my anxiety and helped me feel confident in our strategy. I was impressed by their thorough preparation and attention to detail...I wholeheartedly recommend Jason Fellner and his fantastic team. Their passion for their work and genuine care for clients truly sets them apart. I am incredibly grateful for their exceptional support.”

    Jeffrey L.

  • “Jason and his team helped me navigate through a very delicate but very important matter. Not only did we get to a great outcome, but Jason became a true strategic partner to me in the process. He integrated my various concerns and considerations, and brought a level of expertise and wisdom that got us through a difficult situation. Strong recommend!”

    Omri D.

  • “Hannibal held firm in our strategy and arguments during mediation. He was prepared to stay as late as needed, on a Friday! I told him what my settlement authority was and with his help, we were able to resolve the case for more than $50,000 BELOW our authority. I don’t think there is a single thing I would request him to do differently for us with this case and how he handled it.”

    Heather H.
