Michael Leonard Mastrogiovanni

About me

 Michael has lived in the Tampa Bay area for over 35 years with his family. His career started out in the medical field where he worked as an administrator for over a decade eventually acquiring ownership of several  facilities. Like many working professionals, Michael went to college at night while working full time during the day. He obtained his A.A. degree with honors from St. Petersburg Junior College in 2000, his B.A. degree Cum Laude from University of South Florida in 2002 and went on to attend Stetson University College of Law graduating in 2004.

Upon graduation, Michael was hired by the State Attorney’s Office for the 6th Judicial Circuit in Pinellas County where he gained invaluable experience while handling hundreds of DUI, domestic violence and county court cases, including many jury trials.

During his tenure at the State Attorney’s Office, Michael was sought out by a large law firm where he handled criminal defense, DUI defense, civil litigation and social security disability law. The offices were located in Clearwater, New Port Richey and Spring Hill and he handled cases in Pinellas, Pasco, Hernando, Hillsborough, Sumter, Citrus and Polk counties.

  • Christian A. Myer

    I met Mr. Mastrogiovanni years ago and have always been a fan of his advocacy and unrelenting work ethic to out work the competition. I do not hesitate to pick up the phone and bounce ideas of Mike because he will provide different ideas on how to frame or view an issue. If you are seeking an excellent attorney that is equally impressive in the library as he is in the courtroom.
