I was represented over a period of 3 years on a wrongful death case by Ben Mainzer. Through the hardest period of my life, Ben was able to be sensitive and compassionate while also providing excellent legal work that led to a very positive outcome. I felt that Ben had my best interests at heart in every way. I never felt pressured as we worked through an emotionally challenging process. At the beginning of this process I expressed specific goals above and beyond financial compensation, and Ben and his team were able to meet every one of those goals.

I was in a terrible auto accident, but the attorneys at Reiner, Slaughter, Mainzer & Frankel were very caring and listened to what I had to say. They kept me updated on what I needed to do and what was happening. I always felt they were working their very best for me. They were very successful in my case.
