About me



 As a former Clark County deputy prosecuting attorney and in-house insurance defense attorney for a large international insurance company, litigation is my passion. That is why I have chosen personal injury and criminal defense as my primary practice areas. Having worked these cases from the other side, I know how the insurance companies and prosecution strategize their attacks. Of course, I believe an approrpiate, fair settlement should be the primary goal due to the emotional and financial costs of litigation. However, when the other side does not play fair, and frequently they do not, then my past experience is invaluable and I believe a strong, aggressive offense is necessary to represent my clients against these powerful entities.

    I endorse Quinn because of his excellent professionalism, knowledge of the law, and client satisfaction. I worked opposite of Quinn, as a Prosecuting Attorney, and always looked forward to having cases against each other.

  • Roy C Fernandes

    Quinn and I met while working for the insurance companies and we continue our relationship now prosecuting plaintiff's cases. Quinn is a great person and an even better lawyer. I respect his integrity and admire his doggedness in his pursuit to get the best outcome for his clients. I would highly recommend Quinn to anyone looking for a personal injury lawyer.
