Proskauer Rose LLP fields a sizeable team of corporate and financial taxation experts who routinely advise on matters as diverse as withholding tax, transfer pricing considerations and asset and business migrations. The team is particularly well-regarded for its abilities in tax issues relating to fund formation as well as cross-border transactions within the sports, non-profit and healthcare sectors. Practice head Amanda Nussbaum is based in New York and primarily advises on the structuring of investment funds alongside corporate sports matters. Martin Hamilton and David Miller are also names to note and are located in New York. Hamilton focuses his practice on cross-border M&A, investments and structured financing arrangements, while Miller lends his expertise to tax issues affecting financial instruments and derivatives. Boston-based Philip Lenertz and Kathleen Semanski in New York were both promoted to partner in November 2025. Christine Harlow and Laura Gavioli both joined the New York team in January 2025 and October 2025 respectively. Robert Friedman has departed the firm.
