It is one of New York's most successful law firms, a company that has won US$3 billion ($3.85 billion) in payouts for sick Ground Zero workers, diet pill users and asbestos cancer sufferers.
But Napoli Bern Ripka Shkolnik is now at the centre of its own extraordinary courtroom drama over a power struggle within the firm's offices in the Empire State building, a tawdry office affair and a scorned wife.
A former female lawyer at the firm claims Paul Napoli, one of the founding partners, conducted an 18-month affair with her and that his wife, Marie, has since engaged in a campaign of harassment, threats and stalking - and may have even taken her cat.
Vanessa Dennis is suing the Napolis and the law firm itself for allegedly "aiding, abetting, facilitating and conspiring with Marie's attacks" in a US$9 million defamation suit.
