What clients and colleagues say:

"I am a personal injury litigator for accident victims.For more than twenty years, I have referred some of my personal injury clients to the law firm of Singer Kwinter.In my opinion, Singer Kwinter is first class in its proven ability to represent personal injury accident victims at mediations and also in conducting trials. In cases involving personal injury accidents where I have represented one plaintiff and, due to a conflict of interest, cannot represent a co-plaintiff, I have referred the co-plaintiff to Singer Kwinter. The results for the accident victims have been phenomenal due to the expertise of the lawyers at Singer Kwinter".  S.L.K. November 2013

"Throughout this process, these wonderful people and their colleagues treated us with respect, dignity, and accountability. It was a long and painful legal battle that finally ended this year in an acceptable closure for my family, thanks to Singer and Kwinter’s able and successful intervention. We lost much in the course of these eight years, including a four generation family cohabitation we cherished, but we also gained the help of kind, honest and able professionals that restored our faith in justice and humanity.  We highly recommend these professionals’ services to all those who need and seek conscientious, competent and compassionate legal assistance." The K. Family, October 2013
