WILLIAM L. PETROS was born in Washington, D.C. on October 15, 1958.  He is a graduate of the University of Florida (B.A. 1980), Phi Beta Kappa, Phi Eta Sigma; and Georgetown University Law Center (J.D. cum laude 1983).  Mr. Petros has been a member of The Florida Bar since 1983, the District of Columbia Bar since 1985 and is admitted in the United States District Courts for the Southern and Middle Districts of Florida.  He is a member of the Dade County Bar Association, American Bar Association, American Association for Justice, Florida Justice Association, and a founding member of The Florida Hellenic Bar Association.  Mr. Petros has devoted his entire career to civil trial and appellate litigation in federal and state courts. He has repeatedly been recognized by Super Lawyers in their annual list of Florida's top attorneys. Florida Trend Magazine has continually recognized Mr. Petros in its Legal Elite Edition as one of the top 1.6% lawyers in Florida.   

Mr. Petros began his training at the Miami-Dade County Attorney’s Office gaining extensive trial and appellate experience at one of the most highly respected local governmental attorney’s offices in the country.  Next, he entered private practice with the esteemed law firm of Anderson, Moss becoming a name partner in 1996.  In 1998, he left Anderson, Moss, Sherouse & Petros, P.A. to form the firm Petros & Elegant.  The firm became William Petros Law on March 1, 2017. Mr. Petros has since provided personalized, high-quality representation to select clients involved in complex litigation.   

Mr. Petros is widely regarded as one of the outstanding trial lawyers in Florida.  He has consistently prevailed in Florida’s state and federal courts on behalf of individual and corporate clients in a variety of cases.  In just the past few years, Mr. Petros has successfully tried numerous commercial cases.  For example, Mr. Petros notably defended an international hotel corporation against two multimillion dollar actions.  In the first case, Mr. Petros obtained a defense verdict at trial.  In the next action, he obtained a complete award for the defense (with attorney fees and costs) in arbitration. Similarly, Mr. Petros successfully defended through jury trial and appeal a publicly traded company in a multimillion dollar breach of contract and fiduciary duty action brought by party with which it contracted to jointly provide orthotripsy services throughout the state of Florida.

In addition, Mr. Petros has successfully tried multi-party, wrongful death cases.  Mr. Petros obtained multimillion dollar awards following both a trial in federal court on behalf of adult children whose parents died in a boating accident and after a two-week jury trial in state court on behalf of minor twins whose mother died during childbirth resulting from the negligence of the defendants.  Mr. Petros’s consistent success in the courtroom has directly resulted in very lucrative settlements for the firm’s clients in insurance, medical malpractice and other types of litigation.

Each year, Mr. Petros volunteers his time and performs community service.   He has supported a diverse group of organizations, often providing educational and mentoring opportunities for children in South Florida.  Mr. Petros has served as a coach in youth leagues and in other leadership positions.
