Boies Schiller Flexner announced today that it has elected five attorneys to the partnership, elevated New York partner Eric Brenner to international administrative partner, and made a number of additional changes in business-oriented roles. Daniel Crispino in Fort Lauderdale, Daria Pustilnik in Miami, Tim Smyth in London, Andrew Steinmetz in Armonk, and Melissa Zonne in Los Angeles are the firm’s newest partners.
“Danny, Daria, Tim, Andrew, and Melissa each dedicate themselves to providing our clients with the kind of exceptional advocacy for which we are known, whether in confidential international disputes or in federal and state courts,” said Chairman Matthew L. Schwartz. “This group has proven themselves in high-pressure, complex cases, and we know they will continue to deliver the quality of service that Boies Schiller Flexner clients expect. It’s a pleasure to welcome them to the partnership.”

Among other cases, he is currently litigating two significant consumer class actions and preparing for a jury trial in the Southern District of New York.

Melissa also has broad experience in real estate litigation, including commercial landlord-tenant, lease and ownership disputes, construction defect and construction contract litigation, and rent reset arbitration.
In addition to the five newest partners, Washington, D.C.-based attorney William Harvey was promoted to counsel. Other changes include appointing Eric Brenner to the role of administrative partner for the firm’s international offices; Eric will also continue to serve as firmwide co-general counsel with Amy Neuhardt. Marc Ayala and Craig Wenner have been named co-administrative partners for the New York and Armonk offices, and Alison Anderson is taking over as the administrative partner for Los Angeles. Finally, senior business leaders within the firm have been elevated: Anne Cullen is now the firm’s Chief Human Resources Officer, Robin Davidson is the Chief Marketing and Business Development Officer, and Leon Goldstein is the Chief Information Technology Officer, joining Chief Financial Officer Amy Habie in C-suite roles at the firm. All the changes were effective January 1.
“We anticipate that the newly created international administrative partner role will formalize our focus on cross-border collaboration and integration, an important goal as we continue to think about strategic expansion. Eric embodies our culture as both a long-time BSF lawyer and as a firmwide GC,” Matthew said. “Additionally, given the increased importance of business functions in the practice of law, we sought to create more of a C-suite within the firm by promoting some of our department heads. We congratulate all our lawyers and business professionals on their new positions.”
