“I’ve used Sullivan | Simon multiple times. They’ve written great appellate briefs for my clients on appeal and for trial courts. I regularly recommend them to colleagues.”

“My client was charged with drug distribution in the Eastern District of Pennsylvania and was looking at nine years in jail under the guidelines. Sullivan | Simon wrote a sentencing memo for us and he got one day in jail. I’d say they did a pretty good job for him.”

“Excellent job. I am really happy and I think my client will have little to complain about once he reads the brief.”
