US EditionNew York Lawyer, Ex-Adams Deputy Randy Mastro Joins Law Firm Dechert
Randy Mastro, former NYC first deputy mayor, strengthens Dechert’s securities and complex litigation practice with his 40-year experience in high-stakes disputes and investigations.
- Dechert named Randy Mastro co‑chair of its securities and complex litigation practice on Jan. 15, 2026, joining the roughly 900-lawyer global law firm.
- Following his nine‑month tenure as first deputy mayor, Randy Mastro reportedly resigned in December after learning he'd be let go when Mayor Zohran Mamdani was sworn in on Jan. 1, and Mayor Eric Adams had tapped him last year from King & Spalding.
- A veteran litigator, Randy Mastro brings more than 40 years of experience representing clients including Chris Christie, Chevron , and Madison Square Garden , and served as Rudy Giuliani's chief of staff leading mob crackdowns.
- The firm framed the hire as bolstering its global litigation bench, with Mark Thierfelder saying `Randy is one of the premier litigators and government enforcement practitioners in the country` and noting Dechert's global litigation practice has more than 225 lawyers.
- Saying he'll return to the courtroom, Mastro added, `Who better than a former deputy mayor who litigates to know when the city screws up and how to do something about it? So I fully expect to be back in the courtroom for challenges to government action,` and he plans to continue practicing law.
