Samir Dahman and his team were both extremely attentive, knowledgeable, and swift with communication for any and every question I had during the four months of my legal process. They truly cared about assisting me by any means necessary, even if that meant getting little to no sleep researching and preparing my case for the eventual landslide win. A $0 result from mediation and no further damages — I couldn’t have imagined a more favorable outcome, all resulting from Samir’s hard work and dedication to me and my case.
