About Shannan Sweeney
Shannan Sweeney Rieger earned her law degree from the Paul M. Hebert Law Center at Louisiana State University in 1985, after completing a Bachelor of Science at LSU in 1982. She came through a law school known for producing lawyers who work across both state and federal benches. The chronology of degrees places her entrance into practice in the mid-1980s, a period that shaped many Louisiana litigators.
Her career includes a recorded role as Special Counsel at Kean Miller LLP in 1998. That position placed her inside a firm that handles a broad range of business and litigation matters. Records show she has practiced in Louisiana and been active in legal circles that extend to federal practice in the Fifth Circuit. Those affiliations suggest experience across state and federal filings and court appearances, though her public biography focuses on her institutional ties rather than on a list of individual cases.
Rieger maintains memberships in several professional associations. She is a member of the Baton Rouge Bar Association, the Louisiana State Bar Association and the American Bar Association. She also belongs to the Federal Bar Association and the Fifth Circuit Bar Association. That mix of local and national groups fits a lawyer who works in both state courts and in matters that reach the federal system in the region.
Colleagues describe work in practical terms: advising on procedural matters, briefing appeals and managing litigation logistics in state and federal settings. Her training at the Hebert Law Center would have provided a foundation in Louisiana civil law and procedure, while her membership in federal bar organizations reflects practice that reaches beyond purely state-law issues. She has navigated the professional networks that link Baton Rouge lawyers to broader federal practice.
Throughout her career she has kept a presence at Kean Miller LLP. In 1998 she served formally as Special Counsel there; other listings associate her with the firm in subsequent years. She remains based in Louisiana and engaged with the legal community through her bar memberships and her work at the firm.
As of 2026 she practices at Kean Miller LLP, concentrating on matters arising under Louisiana law and on federal matters in the Fifth Circuit.
