Paul Hastings has hired disputes heavyweight John Buretta (pictured) as co-chair of its litigation department, marking the firm’s fourth partner hire this month.
Buretta joins Paul Hastings’ New York office from Cravath, where he spent more than 12 years, including as chair of its investigations and regulatory enforcement practice.
He brings extensive experience advising clients including corporates, board of directors, and audit committees, as well as company owners, individual board members, and senior management figures, on a wide range of matters including investigations, regulatory enforcements, and civil proceedings.
Before his time at Cravath, Buretta spent 11 years at the Criminal Division of the US Department of Justice (DOJ), most recently as principal deputy assistant attorney general and chief of staff.
While at DOJ he worked on cases related to corporate fraud, money laundering and public corruption, among other crimes, and spent more than two and a half years as director of DOJ’s Deepwater Horizon Task Force.
Global managing partner at Paul Hastings, Sherrese Smith, said: ‘John is widely recognized as one of the best litigators of his generation – a powerhouse whose deep government roots and strategic mindset make him a formidable force for clients facing bet-the-company disputes.’
‘His arrival moves our already top-of-market litigation practice to another level and further demonstrates that Paul Hastings is a destination for elite talent,’ she added.
Also joining Paul Hastings in New York from Cravath was tax partner Andrew Davis, who spent ten years at the firm and made partner in 2021.
Davis brings experience advising on the tax elements of a range of M&A deals, including public-company transactions, PE deals and strategic combinations across industries including tech, manufacturing and financial services.
Paul Hastings has been aggressive in building its M&A practice in recent years, with notable US hires including Eric Schiele, who joined the firm last March as global M&A co-chair from Kirkland & Ellis, and who previously spent just under two decades at Cravath.
The firm hired a further two partners in Washington DC, bringing over two life science regulatory partners from Hogan Lovells: Lynn Mehler and Phil Katz.
Mehler joins as chair of Paul Hastings’ life sciences regulatory practice, having served 15 years at Hogan Lovells, latterly as global life sciences and health care industry co-head. She brings experience advising clients on FDA and US drug enforcement agency regulatory matters.
Meanwhile, Katz joins Paul Hastings after two decades at Hogan Lovells, where she built and led the firm’s pharmaceuticals and biotechnology regulatory practice group before Mehler became practice leader.
Paul Hastings chair Frank Lopez said: ‘The movement of a top-of-the market life sciences regulatory team is incredibly rare and we are grateful that Lynn and Phil share our vision for creating a premier full-service life sciences platform.’
Elsewhere, Latham & Watkins hired Sara Margolis to its complex commercial litigation practice in New York, bringing experience across high-stakes trials and complex disputes in federal and state courts.
Margolis joins following ten years at US litigation boutique MoloLamken, where she made partner in 2021.
Global chair of Latham’s complex commercial litigation practice, Steve Feldman, said in a statement: ‘As regulatory scrutiny intensifies and litigation in these sectors expands, her courtroom experience and proven trial instincts strengthen our roster of young, dynamic trial talent in New York.’
Meanwhile, Paul Weiss has seen its global co-chair of private credit and financial services Anastasia Peterson leave the firm, departing from the New York office to establish a Middle East-focused private capital and advisory platform.
Peterson spent three years at Paul Weiss, based primarily in New York with time also spent in London. She joined as a partner in January 2023, before becoming global co-chair of financial services in November 2023, and spent ten months in as global co-chair of private credit.
Her exit comes as she announces plans to build her own strategic capital and advisory platform ‘focused on structuring and mobilizing capital across the Middle East and other value-adjacent markets, with a core emphasis on private credit, structured finance, and cross-border platform development,’ according to her LinkedIn.
LB understands that her two co-chair roles will not be replaced, with partners Jarryd Anderson and Joe Glatt continuing as chairs of financial services and private credit, respectively.
Also in New York, Simpson Thacher has hired M&A partner Jared Wilner to lead its insurance transactional and regulatory team. He joins from Mayer Brown’s corporate and securities practice and global insurance industry group, where he was a partner for three years.
Fox Rothschild has hired Stephen Aschettino in New York as chair of its new fintech and digital assets practice and co-chair of its financial services industry group.
A fintech veteran, Aschettino joins from Steptoe & Johnson, where he spent two years as payments team leader. Prior to this, Aschettino helped lead and develop fintech teams at Foley & Lardner, Loeb & Loeb, and most recently Norton Rose Fulbright, where he spent three years as US head of fintech.
Also active was Morgan Lewis, with a pair of tax hires in its offices in New York and Miami.
The firm welcomed Daniel Hudson into its Miami private client and taxation practice from Florida business firm Berger Singerman, while in New York it hired Dentons managing associate Alexios Hadji as a partner in its tax practice. Hadji rejoins the firm after six months at Dentons.
Finally in New York, Clifford Chance has brought in Michal Netanyahu as a private equity partner. She joins from Freshfields, where she spent four years as counsel, advising private equity sponsors on cross-border M&A, leveraged buy-outs, joint ventures and restructurings among other matters.
On the West Coast, Arnold & Porter has made two real estate transactions hires as part of its strategic build-out in the region, bringing in partner Katherine Wax in Seattle and counsel Katie McHenry in Los Angeles.
Wax brings the total headcount to 35 lawyers and staff at the Seattle office Arnold & Porter opened last July with a raft of hires from K&L Gtes, including Seattle office head Pallavi Mehta Wahi, now chair of Western US strategic growth at A&P.
Meanwhile, MacHenry joins from K&L Gates, where she spent more than four years as a counsel.
A&P Western US strategic growth chair Wahi said in a statement: ‘With their deep understanding of the West Coast market, they will help drive our continued growth and ability to deliver sophisticated, results-oriented counsel in the region.’

Slaughter and May corporate and M&A co-head Simon Nicholls (pictured) also has faith in the strength of markets going into the new year, saying: ‘There’s a lot of assets looking for a home, and you need to find homes for them.’
One area partners all agree is not in any danger of slowing down is the technology sector, and the data underlines this, with global tech M&A values up 66% to $1.08trn, making it the top-performing sector by some distance.
Regardless of how the market shapes up, it’s clear that partners are excited for the year ahead.
