Biography

Hon. John S. Kastrenakes (Ret.) was a judge for the 15th Judicial Circuit Court of Florida in Palm Beach County. He was appointed to the bench by former Governor Charlie Crist in 2009. Kastrenakes chose to not seek re-election in 2022.


Over the course of his judicial career, he held assignments in the Criminal and Civil Divisions.


Kastrenakes received a B.A. in history from the University of Florida in 1977. He then completed a J.D. at the University of Florida, Fredric G. Levin College of Law, in 1980.


Shortly after graduating from law school, Kastrenakes joined the Office of the State Attorney for the Eleventh Judicial Circuit as an assistant state attorney. His fourteen-year tenure there was briefly interrupted by a short stint in private practice (1984 to 1985). Then, in 1995, he left his post and joined the Office of the United States Attorney for the Southern District of Florida. He served as an assistant United States attorney until his appointment to the bench.
