Personal Background

Mark M. O’Mara has been a fixture in the Central Florida legal community since 1982. While he started his career as a prosecutor for the State Attorney’s office in Seminole County, he crossed to the other side of the courtroom and has served as a defense attorney ever since.

Since the verdict, Mr. O’Mara has decided to use his voice to contribute to the national conversation about race, guns, self-defense, the media, and the criminal justice system and he speaks frequently on these topics.

Moreover, he started a non-profit organization called Justice Outreach, designed to identify and fix problems with the justice system, particularly in juvenile justice, and he is an advocate for change in state and national laws that lead to the over-prosecution of American citizens, whether it be by unbridled prosecutors or inappropriately applied minimum mandatory sentencing schemes.

Mr. O’Mara earned his J.D. from Florida State University College of Law in 1982, and received his undergraduate degree from University of Central Florida in 1979. Mr. O’Mara has taught at the University of Central Florida, Florida State University School of Law, Duquesne School of Law and Harvard Law School; has taught seminars for the Criminal Law Section of the Florida Bar, the National Association of Criminal Defense Attorneys, the Florida Association of Criminal Defense Attorneys, the Georgia Association of Criminal Defense Attorneys, the Central Florida Family Law American Inn of Court, the Family Law Section of the Florida Bar, the Florida Homicide Investigators Association, the University of Buffalo Mock Court Competition, and the Florida Family Law Practice for Paralegals program.
