Peter M. Rosenblum


I have spent my career transforming complex legal issues into opportunities for my clients.

Peter is actively involved in the firm’s corporate and corporate finance practices, with an emphasis on mergers and acquisitions, private equity, venture capital, fund formation and investment, and other public and private offerings of securities. He serves as chair of the firm’s Private Equity Transactions practice and has held numerous leadership roles in M&A and firm management during his tenure with the firm.

Peter’s clients include private equity, hedge, venture capital and other alternative investment funds and investment advisers, as well as public and private companies. For more than four decades, Peter has guided his clients through various market cycles, trends and complicated transactions. He enjoys partnering with clients as they explore opportunities for growth. His peers have described him as one of “just a handful of lawyers in town that command the respect of the entire community." (Chambers USA 2021)

Peter regularly advises institutional and other investors concerning their investments in private funds, co-investments, growth investments and other early and late stage private equity investments. He represents numerous investment advisors and managers of private equity, hedge and other private investment funds, both in the United States and offshore, in connection with formation and operation of their funds and management companies, as well as their transactional matters. 

Peter has broad experience structuring and executing mergers and acquisitions and other complex strategic transactions, including private equity, going private and cross-border transactions, carve-outs, recapitalizations, joint ventures and strategic alliances. He has particular expertise in developing transaction-specific offshore and cross-border structures and limited liability companies and other pass-through vehicles. His clients for this work include public and private companies, private equity firms, stockholders and other company owners and financial advisers. He regularly represents managements, boards of directors and corporate special committees involved in significant transactions.

Peter is principal outside counsel to numerous public and private companies in technology, life sciences, private equity, investment management, consulting, energy and other industries. He provides comprehensive representation concerning private and public placements of equity and debt and other significant fundraising transactions, corporate governance, intellectual property strategies and licensing, management compensation and succession and liquidity events.

Peter was a Co-Managing Partner of Foley Hoag from 2000 to 2005 and served on the Executive Committee from 1997 to 2005 and from 2013 to 2016. He served as Chairman of the firm's Business Department from July 2008 through October 2011. He was Co-Chair of the firm’s M&A Practice Group from 2012 to 2019. Prior to entering the private practice of law, he served as Law Clerk to Chief Justice G. Joseph Tauro of the Massachusetts Supreme Judicial Court.

Peter has lectured and taught classes at Harvard Business School, MIT Sloan School of Management, Boston University School of Law, Duke University School of Law and Bentley University.
