Shannon received her B.A. in Psychology from Emory University in 1999 and graduated cum laude from Florida State University College of Law in 2002. While at Florida State, Shannon was chosen as one of four students from her class to argue in front of the First District Court of Appeal in the Final Four Moot Court Competition. She competed nationally in moot court tournaments as a member of the award-winning Moot Court team, served as the Vice President of the Dispute Resolution Society, and was the recipient of the W. Paul and Erin C. Shelley Academic Scholarship.

Upon graduation, Shannon practiced complex commercial litigation at Trenam Law in Tampa, Florida. Thereafter, she served as a judicial law clerk in the Middle District of Florida for the Hon. Mary S. Scriven (before her elevation to the district court) and for the Hon. James D. Whittemore (who is now a senior district judge). After clerking, Shannon returned to private practice as a contract attorney drafting social security and ERISA appeals. A few years later, Shannon took a sabbatical to focus exclusively on raising her three children.

Since joining Burns, P.A., in 2021, Shannon has briefed or assisted in the briefing of appeals or other appellate matters in the Florida Supreme Court, the Second and Third District Courts of Appeal, and the U.S. Courts of Appeals for the D.C. and Eleventh Circuits. She has also presented oral argument in the Second District.

Shannon grew up in Clearwater, attended Clearwater Central Catholic High School, and resides in Safety Harbor with her husband and three children. She enjoys practicing yoga and traveling with her family.
