FMG Announces New Office Leaders and Attorneys In Philadelphia and Opening of Pittsburgh Office


Atlanta, GA: Freeman Mathis & Gary, LLP (FMG), a leading nationwide specialty litigation firm, is pleased to announce that Bill Catto has joined the firm as a partner and will be Co-Office Leader of the firm’s Philadelphia office.  In addition, Sean Riley will be joining the firm as a partner in the new Pittsburgh office and will work in the Philadelphia office. Also, Courtney Mazzio will be joining the firm in the Philadelphia Office.

Mr. Catto is a highly experienced trial lawyer who concentrates in high exposure litigation and has tried a variety of cases to successful verdicts throughout Pennsylvania. He joins the firm from Litchfield Cavo LLP where he was a partner.

Mr. Riley also brings substantial trial and complex litigation experience from handling cases throughout Pennsylvania and New Jersey. He joins FMG from Litchfield Cavo LLP, as well.


Ben Mathis, FMG’s Managing Partner said, “Bill Catto and Sean Riley are remarkably good lawyers with a range of trial and litigation experience that is hard to find.  They have been the go-to litigation team for significant cases for many years. They both have a very strong work ethic and the credibility of being successful trial lawyers. Bill will lead our professional, management liability and commercial practices in Pennsylvania and Sean will anchor our new Pittsburgh office while maintaining his statewide practice. Courtney adds more bench strength to our employment, professional liability and CD practices.

“Together with Josh Ferguson who will join the Philadelphia office leadership, combined with our new office in Boston, we start the new year having a Northeastern team who collectively have tried hundreds of cases to verdict. While most cases end through dispositive motion or settlement, Bill and Sean and the team we have built will use their court room skills to achieve advantageous resolutions, and our clients can have great confidence we will take the case to successful verdict if needed. No one is bluffing when they say they will try the case and can win it if that is what it takes.”


 Mr. Catto has twenty-five years of courtroom trial experience in defending high value cases such as wrongful death and catastrophic injury, employment, D&O, business devaluation and class actions. His practice also includes complex commercial matters, professional liability and traditional labor law.

Mr. Riley concentrates in commercial and business litigation, employment, nonmedical professional liability and products liability. He has substantial experience in planned communities, class actions, catastrophic loss, construction warranty and contract disputes, toxic tort and premises liability. His experience also includes defending banks, credit unions and other entities against consumer protection lawsuits.


Ms. Mazzio focuses her practice in employment, professional liability and also in construction related disputes. She is admitted to practice in both Pennsylvania and New Jersey. She joins the firm from the Horn Williamson firm in Philadelphia.
