About Cheri L.
Cheri L. Cannon leads a legal career that spans state and federal practice. She serves as managing partner at Tully Rinckey PLLC and is admitted to the Maryland Court of Appeals and the United States Court of Federal Claims. Those admissions shape much of the work that comes through her office.
She earned a B.A. in political science from the University of California, Santa Barbara in 1982. Afterward she attended Georgetown University Law Center, receiving her J.D. in 1985. The combination of a political science undergraduate degree and a Washington, D.C. legal education informed her early approach to litigation and appellate work.
Cannon’s professional path led her into firm leadership. As managing partner at Tully Rinckey PLLC she handles administrative duties alongside client work. She manages firm operations and coordinates case strategies while maintaining an active docket. The role places her at the intersection of practice management and courtroom advocacy.
Her admissions to the Maryland Court of Appeals and the U.S. Court of Federal Claims allow her to represent clients in both appellate and federal claims settings. She appears in matters that require familiarity with federal claims procedures and Maryland appellate practice. That combination requires attention to procedural detail and an ability to frame legal questions for higher courts.
Colleagues and clients encounter Cannon across a range of legal tasks. She spends time preparing appellate briefs, presenting arguments, and overseeing litigation that may involve administrative and contract claims in federal forums. Her practice reflects the procedural demands of appeals and federal claims litigation rather than a single substantive niche.
Outside the courtroom she directs firm priorities and helps shape litigation strategy at Tully Rinckey PLLC. Her work ties daily case management to longer-term appellate planning. She has remained active in cases that proceed to higher levels of review and in proceedings before the Court of Federal Claims.
Cannon continues to lead at Tully Rinckey PLLC while representing clients in matters before the U.S. Court of Federal Claims and the Maryland Court of Appeals, concentrating her practice on appellate and federal claims work.
