Well-regarded for its payments, capital markets, financial services, and transactional practices, Mayer Brown fields a strong team with a ‘wealth of knowledge’. In Washington DC, David Beam is lauded as a ’go-to payments expert’, bringing extensive experience in credit products and specializing in digital payment regulatory matters, including licensing and product structuring. Operating out of New York, Joseph Castelluccio advises on digital assets and crypto-related corporate and business transactions and is noted for bringing ‘tons of experience’ across jurisdictions on regulatory issues, while Anna Pinedo is a leader within the capital markets and structured finance practices, regularly representing issuers and investment banks in financing transactions and advising on structured products and derivatives matters. In Chicago, Joe Pennell focuses on digital transformation and outsourced services transactions, notably with respect to customer-facing payment and lending digital platforms, and in Washington DC, Eric Mitzenmacher provides regulatory compliance advice, particularly within the payments and lending sectors. The arrival of partners Kimberly Hamm and Jennifer Zepralka, both formerly in government roles, further bolsters the team’s regulatory expertise.
