Absolute five star representation. I’m a personal injury and wrongful death litigator based in NYC. When a lifelong friend was badly injured in D.C., I was anxious about where to send her. A colleague recommended Trombly & Singer and I couldn’t be happier that she decided to go with them. Dan Singer did an incredible job for my friend and obtained a recovery exponentially higher than I anticipated. He was quick to answer emails and kept me apprised throughout the years-long process. If I ever need to refer another case to a D.C. lawyer, I won’t hesitate to call him immediately.

— Erin A., August, 2024

After experiencing one of the most challenging events of my lifetime, I discovered the website of Trombly and Singer.
