US firm Proskauer has continued its City finance build-out with the hire of White & Case leveraged finance partner Peter Mason.
The hire marks the latest phase in Proskauer’s strategy to grow its private credit capabilities in the capital, and comes on the back of a flurry of hires last year, including Philip Bowden, the former co-head of banking at Allen & Overy.
Mason, who is joining Proskauer’s global finance practice in London, started his career at Freshfields before joining White & Case as a partner in autumn 2023.
A leveraged finance specialist, he advises on complex cross-border transactions in both Europe and the US, alongside real estate deals and restructurings. Recent matters he was involved in at White & Case included advising creditors on the financing for the £350m acquisition of Alliance Pharma.
Bowden – who now co-heads Proskauer’s global finance practice alongside Justin Breen and Andrew Bettwy in New York – said that the practice was expanding ‘in response to increasing client demand,’ and that the firm was looking to grow its platform to ‘deliver a full suite of leveraged finance solutions’ around the world.
Mason’s hire is the latest in Proskauer’s expansion of its global finance team, with the firm adding a total of eight partners to the practice over the last year.
The buildout began in earnest in July 2024, when the firm sealed the hires of A&O Shearman duo Bowden and Megan Lawrence, followed not long afterwards by three additions from Cahill Gordon & Reindel’s London office – Jake Keaveny, who is now head of European capital markets, Warren Newton and Court Tisdale.
The recruitment continued throughout late 2024 and early 2025, with structured finance specialist and former A&O Shearman and Milbank partner John Goldfinch joining in November, and credit-focused restructuring expert Clare Cottle moving over from Akin in March this year.
More recently, financial services regulatory partner Anna Maleva-Otto joined from Schulte Roth & Zabel ahead of her former firm’s merger with McDermott Will & Emery.
Proskauer now has around 180 lawyers in London, according to its website, including 55 partners.
