Client Testimonials
  • “Dear Mr. Schloss: We will make sure anyone we know who needs legal help gets your name and phone number. As we said before, without your help we know this would have taken much longer and things may have turned out completely different than they have. We both know it takes someone who knows the law and isn’t afraid to go nose to nose with someone just to make sure his client isn’t getting scraps thrown to them by these insurance companies. We also know these adjusters play these intimidation games against workers who are guilty of nothing more than getting hurt while doing their job. It feels great to know they can play all they want, but in the end, they lose. You have taught me so much about patience and the law. My wife and I both believe you have done an excellent job watching out for our best interests. It’s because of your hard work that we have had about the best year since the start of this whole mess.” – Client from Maryland
