Sidley Adds Capital Markets Partner Ellen Park in New York

New York – Sidley is pleased to announce that Ellen Park has joined the firm’s Capital Markets practice as a partner in Sidley’s office in New York. Ms. Park joins from Cravath, Swaine & Moore LLP, where she was a partner in the Capital Markets and Venture Capital & Growth Equity practices. Her arrival follows that of Scott Bennett from Cravath, who recently joined Sidley’s office in New York as Head of Technology Capital Markets.

Ms. Park focuses her practice on capital markets and complex corporate transactions, representing issuers, investors, and financial institutions in a broad range of matters, including IPOs, venture capital and growth equity transactions, and other debt and equity offerings. She also regularly advises clients on mergers and acquisitions, corporate governance, and disclosure matters.

Ms. Park regularly advises venture capital-backed companies, as well as founders, investors, and financial institutions, on a wide range of corporate matters, including pre-IPO financings, IPOs and other capital markets transactions, company structuring, and shareholder arrangements. Her practice spans a broad range of industries, including technology, fintech, digital assets, and artificial intelligence, as well as healthcare and life sciences, consumer products and services, energy and infrastructure, industrials and chemicals, media and entertainment, and retail.

“Ellen is an outstanding addition to our capital markets team. Her practice brings additional strength in venture, growth equity and technology-focused transactions, and further enhances our ability to support clients across the full lifecycle of their capital needs,” said Yvette Ostolaza, the firm’s Management Committee Chair and an Executive Committee member. “Her experience advising leading issuers, sponsors, and financial institutions, combined with her collaborative approach, aligns strongly with our strategic priorities and continued growth in New York.”

“Ellen combines sophisticated capital markets experience with strong relationships across the investment banking and private equity communities,” said Sam Gandhi, global practice leader of the firm’s Capital Markets group and a member of the firm’s Executive Committee. “Having worked closely with Scott Bennett, she has been instrumental in building a dynamic venture and growth equity practice and will play a key role in expanding our capabilities in technology, digital assets, and other high-growth sectors.”
