As a former Criminal Chief at the U.S. Attorney’s Office for the District of South Carolina, which included the Greenville office of the United States Attorney’s Office, Nathan brings unmatched insight into how federal cases are built — and how they can be taken apart.

Experience in the Greenville Federal Courthouse

Federal cases in the Upstate are heard at the Carroll A. Campbell Federal Courthouse in downtown Greenville. Nathan Williams has handled numerous cases in this venue, and he is familiar with the federal judges, prosecutors, and pretrial services officers who shape outcomes here.

Because of his role as former Criminal Chief, Nathan understands how federal cases are prosecuted in Charleston, what prosecutors are likely to pursue, and where opportunities exist to challenge their case.

This is an essential factor when selecting an attorney. Individuals and businesses often consider or hire law firms located outside of South Carolina, because they are out of the area, based on a recommendation, or because they did not look for an attorney in the area where the case is being prosecuted. However, attorneys who do not practice in the federal court where a charge is pending are often unfamiliar with local practices, expectations, and processes. As a result, those attorneys spend valuable time trying to learn the local practice and never reach the level of competence that skilled local lawyers possess. Consequently, they miss opportunities for their clients. Or worse, they apply an approach that may work somewhere else but doesn’t work in South Carolina, and their clients get disastrous results.

This level of local insight — combined with his former DOJ leadership — gives clients an edge in navigating the complex federal process.
