Mariko Shitama Outman



Mariko Shitama Outman assists with all aspects of appellate litigation and trial support in state and federal courts. She works on a wide range of complex commercial matters in state and federal court at the trial and appellate level,  including general business disputes and class actions.

Mariko previously served as a law clerk on Florida’s Second District Court of Appeal to the Honorable Chris W. Altenbernd, who served on the court for 27 years.

Mariko is committed to advocating on behalf of indigent criminal defendants and for equal access to justice. Her note on the unconstitutionality of juvenile life without parole for juveniles convicted of felony murder was published during law school by the Florida Law Review and was cited by the Wyoming Supreme Cour. Mariko clerked for the Equal Justice Initiative during law school, when the U.S. Supreme Court handed down its landmark decision abolishing mandatory sentences of life without parole for juveniles in Miller v. Alabama, a case argued and won by the Equal Justice Initiative. She continues to represent pro bono clients on this issue and others.
