[1] He is the founding and managing partner of the South Florida-based firm Herman Law, and has been described in the media as "the nation's leading attorney when it comes to handling high-profile sexual abuse lawsuits".
[12] He has also represented clients against public figures, including financier Jeffrey Epstein, puppeteer Kevin Clash, and director Bryan Singer.
[15] In one case during this period, in 1995, Herman successfully represented Robin Elkins, a saxophonist who had patented a means of storing and retrieving bits of sound on a computer, a technology that led to electronic voice mail.
[15] Herman first gained national attention in this field representing victims of clergy sexual abuse in over 100 cases against the Archdiocese of Miami.
Herman became one of the first attorneys to successfully defeat this strategy- arguing that the archdiocese committed fraud by keeping a priest's sexual abuse history secret.
It was reported at the time that "Herman is known nationally as a plaintiff's lawyer in clergy sexual abuse cases, but his reputation in Indian law circles is less established".
The lawsuit alleged that Mercieca fondled and performed oral sex on the victim, who was a 13-year-old altar boy at St. James Church in North Miami.
[22] That same year, Herman represented the victims of Rabbi Joel Kolko, who was accused of molesting multiple young students of his yeshiva.
[23] In 2011, Herman won a $100 million verdict for a victim of Father Neil Doherty, a priest of the Archdiocese of Miami accused of drugging and raping church youths.
[24] Herman – along with attorneys Adam Horowitz and Arick Fudali – won a $3 million jury verdict on behalf of a young girl who was sexually abused at Discovery Day Care in 2012.
[25] Testimony showed that the preschooler was abused on multiple occasions by the daycare director's 13-year-old son and that a center employee falsified documents related to the incident.
[26] In 2019, Herman represented New York clergy sex abuse victims in a lawsuit against the Vatican and Pope Francis, contending negligence in addressing misconduct within the priesthood.
Herman filed a civil suit alleging that the victims were as young as 14 years old when they were brought to Epstein's mansion to perform erotic massages.
[28] On November 20, 2012, Herman filed a lawsuit alleging that Clash sexually abused a 15-year-old boy he met on a gay phone chatline.
The plaintiff in the first case, Michael Egan, was a former child model and actor who accused Singer of repeatedly drugging, threatening and forcibly sodomizing him in the late 1990s, beginning when the boy was 15 years old.
[3] Entertainment lawyer Jonathan Handel, who wrote a number of articles about Singer, wrote in a 2017 piece in The Hollywood Reporter that Herman was disciplined for two incidents of misconduct involving dishonesty,[45] including a 1998 incident in which an Oregon District Court had reportedly barred Herman permanently from his courtroom following findings of alleged misrepresentations and dishonesty.
[45] Handel also wrote that between 2014 and 2017, Herman was the debtor in four federal tax liens (from $210,000 to over $900,000), and that two major banks had also filed claims against the attorney for credit due and foreclosure.
