John Gravante was born in New Haven, Connecticut. He received his B.A. in English from Florida Atlantic University in 1999, and his J.D. from the University of Miami School of Law, graduating summa cum laude and finishing second in his class in 2002. While in law school, he served on the University’s Law Review and was champion of the 1L Moot Court competition.

After law school, John served as a judicial clerk for the Honorable Adalberto Jordan in the United States District Court for the Southern District of Florida. He also served as an adjunct professor of Legal Research and Writing at the University of Miami.

As a plaintiff’s attorney, John has extensive experience litigating complex commercial cases, class actions, and personal injury matters. He has played a leading role in some of the largest and most complex class action and antitrust cases in the United States. The representative engagements in which he has been actively involved include a RICO action on behalf of a nationwide class of doctors against major HMOs for systematic reduction and denial of payments, which resulted in settlements valued at hundreds of millions of dollars. Additionally, he has handled numerous securities fraud class actions on behalf of bilked investors, complex commercial disputes involving fraud, as well as a suit against a health insurance company for denial of benefits resulting in the death of the insured. He was heavily involved in a multi-district class action against major banks for deceptive practices related to imposition of improper overdraft fees against their customers. He is currently involved in one of the largest antitrust cases ever filed, challenging the anticompetitive practices of major health insurance companies. John is also significantly involved in representing the class in a case relating to defective and deadly airbags, which involves the largest automotive recall in U.S. history, and has already resulted in settlements valued at over a billion dollars.

John was admitted to the Florida Bar in 2002, and is a member of the American Bar Association, Dade County Bar, American Association For Justice, and Florida Justice Association. He served on the Board of Directors for the Miami-Dade Justice Association during 2008 and 2009.
