  • Don is an outstanding attorney. He remains knowledgeable and current on laws and judicial procedure especially during these changing times. His interpersonal interactions and demeanor put people at ease with his approach and style. One of his strengths is in the courtroom. He is a true litigator. He is very confident and calm as a courtroom lawyer and is quick to identify contradictions, evidentiary issues and other matters that affect the case. For me personally, at a time when I was unfairly treated by my employer after 30 years of loyal and dedicated service, I was at the lowest point in my career. Don was more than just an attorney willing to help. His advice, consultation and recommendations provided me the professional and friendly support I badly needed to get me through a very difficult time.

  • ... Instead of going to an attorney that gave himself a “pet name”, I decided to do some research and find a reputable firm. I found Elkus & Sisson, P.C and a meeting was immediately scheduled. I met with both Don Sisson and Steven Mandelaris. Both made me feel at ease and went into detail on every step I could expect. One sentiment that stood out to both my husband and I was they both wanted me to just concentrate on getting better. At that point, that’s all I needed to do. Mr. Mandelaris was in constant communication with me and was available any time to answer any questions I had. He walked me through completing forms and always made sure I understood the meaning of each document and step I was encountering. I am extremely grateful for all the help Mr. Mandelaris gave me. In the end, all his help allowed me to remedy my injury and receive a proper settlement.

  • This is a great firm! They really helped me out with the insurance company when I got in a car accident. The person's insurance company who T-boned me running a read light tried to hide the fact that I should be compensated money wise for a rental car. Great work Elkus &Sisson!!!
