Christopher L. Sullivan

“At CLS Law, we were the firm that took cases early on that no other firm was equipped to handle, and now we’ve solidified our place in big injury. Our early cases, often when my back was against the wall, created a firm that wins for people who need it most. Those early clients trusted us to take their cases, and we utilized that feedback and data to create something truly special.”
