Client Testimonials for Attorney David Schloss:


“Special thanks to Mr. Schloss and his assistant Suzy Kelly. You guys are the Best of the Best.”- Client from Washington, DC

“Thanks to you, I’m doing great and enjoying my retirement. I’m forever grateful.” -Client from DC

“Thank you again for all of your help. You’ve been wonderful.” -Client from Washington, DC

“Thanks again for your tireless representation. It’s much appreciated!” -Client from Maryland

“Thanks again for doing a great job as always. Without your help we’d be sunk!” -Client from Maryland

“Thank you for all of your hard work over the past five years. You have provided our family with a fresh start on our future and we cannot thank you enough. You are truly a gem.” – Client from Maryland

“David, I recently reviewed our communications during my case back in 1999-2000 and I have to repeat my estimation: You are one wonderful attorney.” -Client from California

“Dear Mr. Schloss: Throughout the years you have done a wonderful job. We appreciate your wisdom, help and guidance. Without that we wouldn’t have made it.” – Client from Maryland

“Dear Mr. Schloss: Everything is going well. Money is invested very well. You’re an ACE in my book! Thanks again!” – Client from Maryland

“Dear Mr. Schloss: I know my wife and I could never repay you for all of your help and kindness during this ordeal. We both want you to know we appreciate everything you and your staff have done for us and continue to do for us. We are both glad you are on our side and not representing the insurance company. When we are young we all have to make a decision of what we want to do with our lives as well as what profession we would like to be involved in. When you made your decision to become a lawyer, you made the perfect decision. There are many lawyers, but there are only a few who dedicate their lives to their profession and are as compassionate as you are about your clients and getting the job done the right way the first time.” – Client from Maryland

“Dear Mr. Schloss: I wish to thank you for the fantastic job that you accomplished yesterday. I hope that you know how much I appreciate what you have done for me. As the saying goes, when you ’re good, you’re good. I consider you as being fantastic.” – Client from West Virginia

“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

“David, I wanted to make sure you knew how much my wife and I both appreciate what you do, and have done for us. We are and have been very fortunate to have someone such as yourself in our corner backing us up for these many years now. Not once have you ever taken the easy road, and you have always been right there making sure we weren’t being taken advantage of. We both know how hard it is for a client and their attorney to get along in some instances, and we also know everyone isn’t always going to see eye to eye when things don’t go the way a client feels they should. Please know you are more than just an attorney. We consider you our friend as well.” – Client from Maryland

“This is going to help me out a lot and I am really thankful for all your help. You have done a great job. Thank you.” – Client from Virginia

“Mr. Schloss: My life and finances have really changed because of you. The blessings of God in heaven sent me a great lawyer. Thank you for everything. You are a friend for life..” – Client from Washington, DC

  • William P. Lightfoot

    I have known David for more than 25 years. He successfully represents people who are injured on the job. No one has a better knowledge of the D.C. worker’s compensation law. He excels at negotiating complicated benefit packages for seriously injured workers, and, when negotiation is not possible, David wins at trial. When the insurance company denies benefits, David is passionate about achieving justice.
