With a proven record of victories against both federal and state prosecutors and powerful insurance companies across Mississippi, our firm stands as one of the most formidable criminal defense and trial law firms serving Gulfport, Hattiesburg, the entire Mississippi Gulf Coast, and the Southeastern United States. We’re not afraid to fight the most powerful opponents and we know how to win.

​​

Many law firms operate “assembly lines” performing a wide range of legal services and employing teams of lawyers to serve huge numbers of clients. By contrast, The Law Offices of Sean Buckley PLLC limits the volume and variety of cases we take to ensure each case and client receives personal attention.

​

Instead of farming out your case to random associates and paralegals, attorney Sean Buckley takes a personal role in every case we handle. We approach each case as an individual challenge – a challenge that’s attached to a real human client, not just the next case coming down the assembly line. When you hire our firm, your case will not be passed down to a junior associate. Attorney Sean Buckley personally handles every case, bringing decades of experience, trial skill, and strategic insight to the fight for your future.

We believe our qualifications speak for themselves –
