New York, July 31, 2025 – Alvarez & Marsal Tax, (A&M Tax), an affiliate of leading global professional services firm Alvarez & Marsal (A&M), has appointed Michael Bertolino as its first Global Markets Leader. The newly created role reflects the firm’s commitment to scaling international capabilities, enhancing cross-border collaboration, and delivering seamless solutions to clients worldwide.

Mr. Bertolino, who joins as Managing Director, will lead efforts to strengthen client engagement across global markets, aligning strategy, talent acquisition, and services to support growth. His arrival coincides with a series of internal leadership appointments that collectively expand the firm’s capacity to address complex, multi-jurisdictional needs. 

“Clients are focused on value, agility and an advisor’s ability to collaborate as a strategic partner,” Ernesto “Ernie” Perez, Global Head of A&M Tax, said, “The timing of Michael joining aligns with our ongoing ambitious growth plans and his experience as a leader and advisor will strengthen our focus on outcomes and high-touch execution for our clients around the world.”

Prior to joining A&M, Mr. Bertolino was with EY where he held the position of Global Leader, People Advisory Services. Previously, he was Deputy Global Vice Chair of Tax based in the UK.

Mr. Bertolino noted, “A&M is known for its entrepreneurial culture along with a singular focus on execution. The result is the firm’s unmatched agility, obsession with client service and a hands-on problem-solving ethos that sets it apart from the herd of firms making promises without performance. This is a team of world-class professionals who lead by example, innovate with purpose, and consistently deliver results far beyond decks and strategy.”

Concurrent with Mr. Bertolino joining, A&M Tax announced several key leadership appointments aimed at supporting growth and integration:

• Adam Benson has been named Head of A&M Tax U.S. He will retain leadership of the U.S. Global Transaction Tax (GTT) practice as well. Adam has been with the organization for 14 years and has led the GTT U.S. team since 2018.

Mr. Perez commented, "I am honored to announce these appointments.
