About Melanie
Melanie Campbell began her academic life in the sciences. She earned a B.S. in Neuroscience and Psychology from Kings College in 2000. That foundation in empirical study and human behavior preceded a turn to law. She completed her J.D. at St. Thomas University School of Law in 2004 and added an LL.M. in International Taxation & Finance from Thomas Jefferson School of Law in 2009.
Her educational path describes a gradual narrowing of interests. The undergraduate work supplied tools for close observation and structured analysis. Law school introduced doctrine and procedure. The LL.M. brought rigorous study of cross-border tax rules and financial regulation. Those layers of training give her a technical grounding that is uncommon among general practitioners.
Campbell is admitted to practice in Florida and before the U.S. Court of Appeals for the Eleventh Circuit. Those credentials allow her to handle matters in state venues and to participate in federal appellate work when cases require it. Beyond the admissions themselves, the combination of state and federal standing positions her to follow disputes from trial courts into higher courts when necessary.
Her career has combined academic specialization and practical work. Her graduate study in international taxation and finance signals an interest in matters that cross national lines or involve complex fiscal structures. At the same time, her early legal training provided a base in core litigation and transactional practice. This blend shapes how she evaluates problems: an eye for technical tax implications and the procedural steps that make or break a case.
She practices at Decker & Campbell. At the firm she advises clients whose matters fall within the jurisdictions she maintains. Her work draws on the LL.M. training and the analytical habits formed during her undergraduate study.
Colleagues describe her approach as methodical. She breaks down technical rules into discrete questions. That style helps in tax and finance work, where small factual differences change outcomes. It also helps when preparing briefs for appellate review, where clarity and precision matter.
As of 2026 she remains active in practice at Decker & Campbell. Her practice focuses on matters that involve international taxation and finance within the scope of Florida and Eleventh Circuit practice.
