WSHB Support Services, the management services organization supporting Wood Smith Henning & Berman LLP, today announced that Michael Inserra, former Deputy Managing Partner and Senior Vice Chair, EY Americas, and Senior Advisor to Charlesbank Capital Partners (“Charlesbank”), has joined its Board.
WSHB Support Services formed in October 2026, while simultaneously receiving a strategic investment from Charlesbank. Wood Smith Henning & Berman LLP remains an independent law firm, with its lawyers retaining sole authority over the practice of law and client matters. WSHB Support Services is the management services organization (“MSO”) that provides non-legal operational infrastructure and support to the law firm.
Mr. Inserra will serve on the Board of WSHB Support Services alongside the law firm’s Management Committee and representatives from Charlesbank. This appointment does not change the Management Committee of the law firm, which remains independently governed by lawyers.
Mr. Inserra brings more than 30 years of leadership experience in professional and financial services. He spent more than two decades at EY, where he most recently served as Deputy Managing Partner and Senior Vice Chair, EY Americas, and was a member of both the EY US and Americas Executive Boards. At Charlesbank, he is a Senior Advisor, supporting the firm’s investment team on business and professional services investments.
Mr. Inserra currently serves as Chairman of the Board of Directors of Berkeley Research Group (BRG), and is a member of the Boards of Directors of Baker Tilly and Brighthouse Financial. He brings first-hand experience leading and governing large professional services firms as they scale.
“Mike’s first-hand experience leading large professional services firms through significant transformation will be invaluable to us as we continue to grow WSHB Support Services to best serve our clients, our lawyers, and our Support Services colleagues,” said Daniel Berman, Executive Chairman and Co-Founder of Wood Smith Henning & Berman LLP and Chief Executive Officer of WSHB Support Services.
“Mike has been a trusted advisor to Charlesbank for many years, and we’re excited for the WSHB team to benefit from his insight and experience during what may prove to be one of the most dynamic and transformative periods ever for professional services firms,” said Mutian Rui, Principal at Charlesbank.
“I’m thrilled to join the WSHB Support Services Board, as WSHB continues to build on its strong foundation as a leader in the litigation defense space,” said Mike Inserra, Senior Advisor to Charlesbank.
