About Paul

There are not many people more familiar with Clearwater, Florida than Paul A. Gionis.  Born to Greek immigrant parents who settled on Clearwater Beach in the 70’s, Paul grew up a “beach kid” fishing the shores of Clearwater Beach and helping his parents at their various beach businesses; Fritz’s Market and the Waterfront Restaurant (now Clear Skyz Cafe) for those of you who were around in the old days.

In later years, Paul went on to attend Clearwater Central Catholic High School, the University of Florida and the University of Florida Levin College of Law where he received his law degree.

Upon graduating, Paul moved back to Clearwater to take a position with the Tampa satellite office of Jones, Verras & Freiberg, a New Orleans based mass torts law firm.  Paul later began working for the State Attorney’s Office of the Sixth Judicial Circuit, so that he could gain trial experience.  Paul left the State Attorney’s Office to engage in civil practice, and ultimately opened his own firm in 2011.  He currently specializes in trial and litigation practice, serious injury cases, eminent domain cases, real estate transactions and probate litigation.
